| Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
| Overview and Basis of Presentation | Overview and Basis of Presentation Description of Business Okta, Inc. (the Company) is the leading independent identity management platform for the enterprise. The Okta Identity Cloud enables the Company’s customers to securely connect people to technology, anywhere, anytime and from any device. The Company was incorporated in January 2009 as Saasure Inc., a California corporation, and was later reincorporated in April 2010 under the name Okta, Inc. as a Delaware corporation. The Company is headquartered in San Francisco, California. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in conformity with U.S. generally accepted accounting principles (GAAP). All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of January 31, 2019, included herein, was derived from the audited financial statements as of that date. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the results of operations for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending January 31, 2020 or any future period. The Company’s fiscal year ends on January 31. References to fiscal 2020, for example, refer to the fiscal year ending January 31, 2020. The condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in the Company’s Form 10-K filed with the Securities and Exchange Commission (SEC) on March 14, 2019. Effective February 1, 2018, the Company adopted the requirements of Accounting Standards Update (ASU) No. 2016-02, Leases (ASC 842) as discussed in Note 2. All amounts and disclosures set forth in this Form 10-Q have been updated to comply with this standard, as indicated by references to "as adjusted" in these condensed consolidated financial statements and related notes. Certain reclassifications of prior period amounts have been made in our condensed consolidated financial statements to conform to the current period presentation. We reclassified $14.8 million of certain accrued accounts payable to accrued expenses as of January 31, 2019. These reclassifications had no impact on net loss, stockholders’ equity or cash flows as previously reported. Convertible Senior Notes In February 2018, the Company issued $345.0 million aggregate principal amount of 0.25% convertible senior notes due February 15, 2023 (2023 Notes) in a private offering, including the initial purchasers’ exercise in full of their option to purchase additional notes. The Company received aggregate proceeds of $345.0 million, before deducting costs of issuance of $10.0 million. See Note 9 for additional details. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. Actual results could vary from those estimates. The Company’s most significant estimates include the stand alone selling price (SSP) for each distinct performance obligation included in customer contracts with multiple performance obligations, the determination of the period of benefit for deferred commissions, the determination of the effective interest rate of the liability components of the 2023 Notes, the determination of the incremental borrowing rate used for operating lease liabilities, the valuation of deferred income tax assets, contingencies and the valuation of acquired intangible assets.

| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Accounting Standards and Significant Accounting Policies | Accounting Standards and Significant Accounting Policies Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (ASC 842), which requires lessees to record a right-of-use asset and a corresponding lease liability on their balance sheet for most leases. The Company adopted the requirements of ASC 842 as of February 1, 2019, using the modified retrospective method for leases that existed as of February 1, 2017, or were entered into thereafter. The modified retrospective method provides a method for recording existing leases at adoption and in comparative periods that approximates the results of a full retrospective approach. In order to simplify an entity’s transition, ASC 842 provides a package of three practical expedients, which must be elected together and applied consistently to all of an entity’s leases. The Company elected to utilize the package of practical expedients and, therefore, did not reassess:
As of the later of February 1, 2017 or each lease’s respective commencement date, the Company recorded lease liabilities equal to the present value of the remaining minimum lease payments and right-of-use assets equal to the corresponding lease liability adjusted for (i) any prepaid or accrued lease payments, (ii) the remaining balance of any lease incentives received, (iii) unamortized initial direct costs and (iv) any impairments. The Company adjusted its condensed consolidated balance sheet from amounts previously reported due to the adoption of ASC 842. Select condensed consolidated balance sheet line items, which reflect the adoption of ASC 842, are as follows (in thousands):
The Company’s condensed consolidated statement of cash flows reflects the adoption of ASC 842. The adoption of ASC 842 did not have an impact on cash provided by or used in operating, investing, or financing activities or on the Company’s condensed consolidated statements of operations. Significant Accounting Policies The Company’s significant accounting policies are discussed in “Note 2. Summary of Significant Accounting Policies” in Item 8. Financial Statements and Supplementary Data of its Form 10-K for the fiscal year ended January 31, 2019. Except for the accounting policies for operating leases that were updated below as a result of adopting ASC 842, there have been no significant changes to these policies for the six months ended July 31, 2019. Operating Leases and Incremental Borrowing Rate The Company leases office space under operating leases with expiration dates through 2028. The Company determines whether an arrangement constitutes a lease and records lease liabilities and right-of-use assets on its consolidated balance sheets at lease commencement. Lease liabilities are measured based on the present value of the total lease payments not yet paid discounted based on the more readily determinable of the rate implicit in the lease or the Company’s incremental borrowing rate, which is the estimated rate the Company would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease. The estimation of the incremental borrowing rate is based on an analysis of publicly traded debt securities of companies with similar credit and financial profiles. Right-of-use assets are measured based on the corresponding lease liability adjusted for (i) payments made to the lessor at or before the commencement date, (ii) initial direct costs incurred and (iii) tenant incentives under the lease. Recognition of rent expense begins when the lessor makes the underlying asset available to the Company. The Company does not assume renewals or early terminations of its leases unless it is reasonably certain to exercise these options at commencement and does not allocate consideration between lease and non-lease components. For short-term leases, the Company records rent expense in its condensed consolidated statements of operations on a straight-line basis over the lease term and records variable lease payments as incurred. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. This guidance is effective for the Company on February 1, 2020 with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15), which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in Accounting Standards Codification 350-40 to determine which implementation costs to defer and recognize as an asset. This guidance is effective for the Company on February 1, 2020 with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements.

All short-term investments were designated as available-for-sale securities as of July 31, 2019 and January 31, 2019. The Company’s short-term investments as of July 31, 2019 and January 31, 2019 all mature within one year, as follows (in thousands):
The Company had 7 and 34 short-term investments in unrealized loss positions as of July 31, 2019 and January 31, 2019, respectively. There were no material gross unrealized gains or losses from available-for-sale securities and no material realized gains or losses from available-for-sale securities that were reclassified out of accumulated other comprehensive income for the three and six months ended July 31, 2019 or 2018. For available-for-sale debt securities that have unrealized losses, the Company evaluates whether (i) the Company has the intention to sell any of these investments and (ii) it is not more likely than not that the Company will be required to sell any of these available-for-sale debt securities before recovery of the entire amortized cost basis. Based on this evaluation, the Company determined that there were no other-than-temporary impairments associated with short-term investments as of July 31, 2019 and January 31, 2019.

| Fair Value Measurements | Fair Value Measurements The Company measures its financial assets at fair value each reporting period using a fair value hierarchy that prioritizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure as follows: Level 1-Valuations based on observable inputs that reflect quoted prices for identical assets or liabilities in active markets. Level 2-Valuations based on inputs that are directly or indirectly observable in the marketplace. Level 3-Valuations based on unobservable inputs that are supported by little or no market activity. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis using the above input categories (in thousands):
The carrying amounts of certain financial instruments, including cash held in banks, accounts receivable and accounts payable approximate fair value due to their short-term maturities and are excluded from the fair value table above. Fair Value Measurements of Other Financial Instruments The following table presents the carrying amounts and estimated fair values of our financial instruments that are not recorded at fair value on the condensed consolidated balance sheets (in thousands):
The difference between the principal amount of the 2023 Notes, $345.0 million, and the net carrying amount before unamortized debt issuance costs represents the unamortized debt discount (See Note 9 for additional details). The estimated fair value of the 2023 Notes, which are Level 2 financial instruments, was determined based on the quoted bid price of the convertible senior notes in an over-the-counter market on the last trading day of the reporting period. As of July 31, 2019, the difference between the net carrying amount of the 2023 Notes and estimated fair value represents the equity conversion value premium the market assigned to the 2023 Notes. Based on the closing price of our common stock of $130.83 on July 31, 2019, the if-converted value of the 2023 Notes exceeded the principal amount of $345.0 million.

| Debt Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Convertible Senior Notes, Net | Convertible Senior Notes, Net Convertible Senior Notes The 2023 Notes are senior, unsecured obligations of the Company, and bear interest at a fixed rate of 0.25% per year. Interest is payable in cash semi-annually in arrears on February 15 and August 15 of each year, beginning on August 15, 2018. The 2023 Notes mature on February 15, 2023 unless earlier repurchased or converted. The Company may not redeem the 2023 Notes prior to maturity. The total net proceeds from the 2023 Notes, after deducting initial purchasers’ discounts and debt issuance costs, was approximately $335.0 million. The terms of the 2023 Notes are governed by an Indenture by and between the Company and Wilmington Trust, National Association, as Trustee (the Indenture). Upon conversion, the 2023 Notes may be settled in cash, shares of Class A common stock or a combination of cash and shares of Class A common stock, at the Company’s election. It is the Company’s current intent to settle the principal amount of the 2023 Notes with cash. The 2023 Notes are convertible at an initial conversion rate of 20.6795 shares of Class A common stock per $1,000 principal amount of 2023 Notes, which is equal to an initial conversion price of approximately $48.36 per share of Class A common stock, subject to adjustment under certain circumstances in accordance with the terms of the Indenture. Prior to the close of business on the business day immediately preceding October 15, 2022, holders of the 2023 Notes may convert all or a portion of their 2023 Notes only in multiples of $1,000 principal amount, under the following circumstances:
On or after October 15, 2022 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their 2023 Notes regardless of the foregoing circumstances. For at least twenty trading days during the period of thirty consecutive trading days ended July 31, 2019, the last reported sale price of the Company’s common stock was equal to or exceeded 130% of the conversion price of the 2023 Notes on each applicable trading day. As a result, the 2023 Notes are convertible at the option of the holders during the fiscal quarter ending October 31, 2019 and were classified as current liabilities on the condensed consolidated balance sheet as of July 31, 2019. During the three months ended July 31, 2019, the Company received a request to convert an immaterial amount of 2023 Notes. Holders of the 2023 Notes who convert their 2023 Notes in connection with certain corporate events that constitute a make-whole fundamental change (as defined in the Indenture) are, under certain circumstances, entitled to an increase in the conversion rate. Additionally, in the event of a corporate event that constitutes a fundamental change (as defined in the Indenture), holders of the 2023 Notes may require the Company to repurchase all or a portion of their 2023 Notes at a price equal to 100% of the principal amount of the 2023 Notes being repurchased, plus any accrued and unpaid interest. In accounting for the issuance of the 2023 Notes, the Company separated the 2023 Notes into liability and equity components. The carrying amounts of the liability components were calculated by measuring the fair value of similar liabilities that do not have associated convertible features. The carrying amount of the equity components representing the conversion option were determined by deducting the fair value of the liability component from the par value of the 2023 Notes. The Company bifurcated the conversion option of the 2023 Notes from the debt instrument, classified the conversion option in equity and will accrete the resulting debt discount as interest expense over the contractual term of the 2023 Notes using the effective interest rate method. The equity component is not remeasured as long as the Notes continue to meet the conditions for equity classification. The effective interest rate of the liability component of the 2023 Notes is 5.68%. This interest rate was based on the interest rates of similar liabilities held by other companies with similar credit risk ratings at the time of issuance that did not have associated convertible features. The following table sets forth total interest expense recognized related to the 2023 Notes (in thousands):
Total issuance costs of $10.0 million related to the 2023 Notes were allocated between liability and equity in the same proportion as the allocation of the total proceeds to the liability and equity components. Issuance costs attributable to the liability component are being amortized to interest expense over the respective term of the 2023 Notes using the effective interest rate method. The issuance costs attributable to the equity component were netted against the respective equity component in Additional paid-in capital. The Company recorded liability issuance costs of $7.7 million and equity issuance costs of $2.3 million. The 2023 Notes, net consisted of the following (in thousands):
(1) Included in the condensed consolidated balance sheets within Additional paid-in capital. Note Hedges In connection with the pricing of the 2023 Notes, the Company entered into convertible note hedge transactions with respect to its Class A common stock (the Note Hedges). The Note Hedges are purchased call options that give the Company the option to purchase, subject to anti-dilution adjustments substantially identical to those in the 2023 Notes, approximately 7.1 million shares of its Class A common stock for $48.36 per share (subject to adjustment), corresponding to the approximate initial conversion price of the 2023 Notes, exercisable upon conversion of the 2023 Notes. The Note Hedges will expire in 2023, if not exercised earlier. The Note Hedges are intended to offset potential dilution to the Company’s Class A common stock and/or offset the potential cash payments that the Company could be required to make in excess of the principal amount upon any conversion of the 2023 Notes under certain circumstances. The Note Hedges are separate transactions and are not part of the terms of the 2023 Notes. The Company paid an aggregate amount of $80.0 million for the Note Hedges. The amount paid for the Note Hedges was recorded as a reduction to Additional paid-in capital in the condensed consolidated balance sheets. Warrants In connection with the issuance of the 2023 Notes, the Company also entered into separate warrant transactions pursuant to which it sold net-share-settled (or, at the Company’s election subject to certain conditions, cash-settled) warrants (the Warrants) to acquire, subject to anti-dilution adjustments, up to approximately 7.1 million shares over 80 scheduled trading days beginning in May 2023 of the Company’s Class A common stock at an initial exercise price of $68.06 per share (subject to adjustment). If the Warrants are not exercised on their exercise dates, they will expire. If the market value per share of the Company’s Class A common stock exceeds the applicable exercise price of the Warrants, the Warrants could have a dilutive effect on the Company’s Class A common stock unless, subject to the terms of the Warrants, the Company elects to cash settle the Warrants. The Warrants are separate transactions and are not part of the terms of the 2023 Notes or the Note Hedges. The Company received aggregate proceeds of $52.4 million from the sale of the Warrants in connection with the 2023 Notes. The proceeds from the sale of the Warrants was recorded as an increase to Additional paid-in capital in the condensed consolidated balance sheets.

| Income Tax Disclosure [Abstract] | |
| Income Taxes | Income Taxes For the three and six months ended July 31, 2019, the Company recorded a tax benefit of $1.5 million and $2.6 million, respectively, on pretax losses of $44.5 million and $97.6 million, respectively. The effective tax rate for the three and six months ended July 31, 2019 was 3.3% and 2.7%, respectively. The effective tax rate differs from the statutory rate primarily as a result of not recognizing deferred tax assets for U.S. losses due to a full valuation allowance against U.S. deferred tax assets, release of the valuation allowance in the United States in connection with the Azuqua acquisition and excess tax benefits from stock-based compensation in the United Kingdom. These tax benefits were partially offset by income tax expense in profitable foreign jurisdictions and U.S. state taxes. For the three and six months ended July 31, 2018, the Company recorded a tax benefit of $1.0 million and $1.2 million, respectively, on pretax losses of $40.2 million and $66.4 million, respectively. The effective tax rate for the three and six months ended July 31, 2018 was 2.5% and 1.8%, respectively. The effective tax rate differs from the statutory rate primarily as a result of not recognizing a deferred tax asset for U.S. losses due to having a full valuation allowance against U.S. deferred tax assets, release of the valuation allowance in the United States in connection with the ScaleFT acquisition and excess tax benefits from stock-based compensation in the United Kingdom. These tax benefits were partially offset by income tax expense in profitable foreign jurisdictions and U.S. state taxes.

| Net Loss Per Share | Net Loss Per Share The following table presents the calculation of basic and diluted net loss per share (in thousands, except per share data):
As the Company was in a loss position for all periods presented, basic net loss per share is the same as diluted net loss per share as the inclusion of all potential common shares outstanding would have been anti-dilutive. Potentially dilutive securities that were not included in the diluted per share calculations because they would be anti-dilutive were as follows (in thousands):
The Company expects to settle the principal amount of the 2023 Notes in cash, and therefore, the Company uses the treasury stock method for calculating any potential dilutive effect of the conversion option on diluted net income per share, if applicable. The conversion option of the 2023 Notes and exercise rights of the Warrants will have a dilutive impact on net income per share of common stock when the average market price per share of the Company’s Class A common stock for a given period exceeds the conversion price of the 2023 Notes of $48.36 per share and exercise price of the Warrants of $68.06 per share, respectively. During the three months ended July 31, 2019, the weighted average price per share of the Company’s Class A common stock exceeded the conversion price of the 2023 Notes and exercise price of the Warrants; however, since the Company is in a net loss position there was no dilutive effect during any period presented.

Accounting Standards and Significant Accounting Policies (Policies) |
6 Months Ended | ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Jul. 31, 2019 | |||||||||||||
| Accounting Policies [Abstract] | |||||||||||||
| Basis of Presentation | The accompanying unaudited condensed consolidated financial statements, which include the accounts of the Company and its wholly owned subsidiaries, have been prepared in conformity with U.S. generally accepted accounting principles (GAAP). | ||||||||||||
| Principles of Consolidation | All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of January 31, 2019, included herein, was derived from the audited financial statements as of that date. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the results of operations for the interim periods presented, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending January 31, 2020 or any future period. | ||||||||||||
| Fiscal Period | The Company’s fiscal year ends on January 31. References to fiscal 2020, for example, refer to the fiscal year ending January 31, 2020. | ||||||||||||
| Reclassifications | Certain reclassifications of prior period amounts have been made in our condensed consolidated financial statements to conform to the current period presentation. | ||||||||||||
| Use of Estimates | The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company bases its estimates on historical experience and on other assumptions that its management believes are reasonable under the circumstances. Actual results could vary from those estimates. The Company’s most significant estimates include the stand alone selling price (SSP) for each distinct performance obligation included in customer contracts with multiple performance obligations, the determination of the period of benefit for deferred commissions, the determination of the effective interest rate of the liability components of the 2023 Notes, the determination of the incremental borrowing rate used for operating lease liabilities, the valuation of deferred income tax assets, contingencies and the valuation of acquired intangible assets.
|
||||||||||||
| Operating Leases and Incremental Borrowing Rate | The Company leases office space under operating leases with expiration dates through 2028. The Company determines whether an arrangement constitutes a lease and records lease liabilities and right-of-use assets on its consolidated balance sheets at lease commencement. Lease liabilities are measured based on the present value of the total lease payments not yet paid discounted based on the more readily determinable of the rate implicit in the lease or the Company’s incremental borrowing rate, which is the estimated rate the Company would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease. The estimation of the incremental borrowing rate is based on an analysis of publicly traded debt securities of companies with similar credit and financial profiles. Right-of-use assets are measured based on the corresponding lease liability adjusted for (i) payments made to the lessor at or before the commencement date, (ii) initial direct costs incurred and (iii) tenant incentives under the lease. Recognition of rent expense begins when the lessor makes the underlying asset available to the Company. The Company does not assume renewals or early terminations of its leases unless it is reasonably certain to exercise these options at commencement and does not allocate consideration between lease and non-lease components. For short-term leases, the Company records rent expense in its condensed consolidated statements of operations on a straight-line basis over the lease term and records variable lease payments as incurred.
|
||||||||||||
| Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted | In February 2016, the Financial Accounting Standards Board (FASB) issued ASU No. 2016-02, Leases (ASC 842), which requires lessees to record a right-of-use asset and a corresponding lease liability on their balance sheet for most leases. The Company adopted the requirements of ASC 842 as of February 1, 2019, using the modified retrospective method for leases that existed as of February 1, 2017, or were entered into thereafter. The modified retrospective method provides a method for recording existing leases at adoption and in comparative periods that approximates the results of a full retrospective approach. In order to simplify an entity’s transition, ASC 842 provides a package of three practical expedients, which must be elected together and applied consistently to all of an entity’s leases. The Company elected to utilize the package of practical expedients and, therefore, did not reassess:
As of the later of February 1, 2017 or each lease’s respective commencement date, the Company recorded lease liabilities equal to the present value of the remaining minimum lease payments and right-of-use assets equal to the corresponding lease liability adjusted for (i) any prepaid or accrued lease payments, (ii) the remaining balance of any lease incentives received, (iii) unamortized initial direct costs and (iv) any impairments. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. This guidance is effective for the Company on February 1, 2020 with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (ASU 2018-15), which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in Accounting Standards Codification 350-40 to determine which implementation costs to defer and recognize as an asset. This guidance is effective for the Company on February 1, 2020 with early adoption permitted. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements.

- Definition The estimated measure of the maximum percentage by which a share price is expected to fluctuate during a period. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period. No definition available.
