OAuth 2.0 Token Revocation (2024)

FAQs

How to revoke an OAuth2 token? ›

To revoke a refresh token, send a POST request to https://{yourDomain}/oauth/revoke . The /oauth/revoke endpoint revokes the entire grant, not just a specific token. Use the /api/v2/device-credentials endpoint to revoke refresh tokens.

Token revocation is a mechanism that enables an app to invalidate authentication tokens.

Once issued, access tokens and ID tokens cannot be revoked in the same way as cookies with session IDs for server-side sessions. As a result, tokens should be issued for relatively short periods, and then refreshed periodically if the user remains active.

Yes, when a user logs out, the refresh token should be invalidated automatically.

Open Settings. Select Token Allowances. Select the token allowance you'd like to revoke by clicking Revoke. Note that there is a network fee for revoking allowances.

There is no way to invalidate them since they are bearer tokens. If the token is used for accessing sensitive resources, Auth0 recommends using a short access token lifetime to mitigate the risk of someone copying a token and then logging out.

Revoking an Offer

This means that if you make an offer and the other party wants some time to think it through, or makes a counteroffer with changed terms, you can revoke your original offer. Once the other party accepts, however, you'll have a binding agreement. Revocation must happen before acceptance.

Deleting a token marks a token as deleted, though it will remain in the ledger. The operation must be signed by the specified Admin Key of the Token. If the Admin Key is not set, the Transaction will result in TOKEN_IS_IMMUTABlE.

Token Revocation Mechanism

Another way to manage access tokens is by revoking them when they are no longer needed or when they are compromised. Token revocation is the process of invalidating a token before it expires, thereby preventing it from being used to access protected resources.

How do I remove an access token? ›

To revoke an access token, specify type accesstoken. To revoke both the access and refresh tokens, specify type refreshtoken. When it sees type refreshtoken, Edge assumes the token is a refresh token. If that refresh token is found, then it is revoked.

Currently, access tokens are valid until they expire regardless of the fact of the user may log out. In terms of security, invalidating access tokens right after the user logs out would reduce the window of opportunity for an attack.

Understanding token revocation

A typical case might be when a user logs out of an OAuth-enabled app. A revoked token will no longer be useful for authorization. After a token has been revoked, if an app presents that token to an API proxy, an OAuthV2 policy with an Operation of VerifyAccessToken will reject that token.

Note: You cannot revoke access tokens. Access tokens are short-lived and by default valid for 1 hour. However, when the refresh tokens are revoked, the application will not be able to redeem the refresh tokens (long-lived tokens) to acquire new access tokens.

The access token is used to authenticate API requests to access protected resources, while the refresh token is used to obtain new access tokens once the current ones expire.

Call and write the company. Tell the company that you are taking away your permission for the company to take automatic payments out of your bank account. This is called “revoking authorization.” If you decide to call, be sure to send the letter after you call and keep a copy for your records.

Revocation can happen manually via the API, via the vault lease revoke cli command, the user interface (UI) under the Access tab, or automatically by Vault. When a lease is expired, Vault will automatically revoke that lease. When a token is revoked, Vault will revoke all leases that were created using that token.
