When a token has expired or has been revoked, it can no longer be used to authenticate Git and API requests. It is not possible to restore an expired or revoked token, you or the application will need to create a new token.
This article explains the possible reasons your GitHub Enterprise Cloud token might be revoked or expire.
Note: When a personal access token or OAuth token expires or is revoked, you may see an
oauth_authorization.destroy action in your security log. For more information, see "Reviewing your security log."
When you create a personal access token, we recommend that you set an expiration for your token. Upon reaching your token's expiration date, the token is automatically revoked. For more information, see "Managing your personal access tokens."
If a valid OAuth token, GitHub App token, or personal access token is pushed to a public repository or public gist, the token will be automatically revoked.
GitHub Enterprise Cloud will automatically revoke an OAuth token or personal access token when the token hasn't been used in one year.
You can revoke your authorization of a GitHub App or OAuth app from your account settings which will revoke any tokens associated with the app. For more information, see "Reviewing and revoking authorization of GitHub Apps" and "Reviewing your authorized OAuth apps."
Once an authorization is revoked, any tokens associated with the authorization will be revoked as well. To reauthorize an application, follow the instructions from the third-party application or website to connect your account on GitHub.com again.
The owner of an OAuth app can revoke an account's authorization of their app, this will also revoke any tokens associated with the authorization. For more information about revoking authorizations of your OAuth app, see "Apps."
OAuth app owners can also revoke individual tokens associated with an authorization. For more information about revoking individual tokens for your OAuth app, see "OAuth Authorizations".
There is a limit of ten tokens that are issued per user/application/scope combination. If an application creates more than 10 tokens for the same user and the same scopes, the oldest tokens with the same user/application/scope combination will be revoked.
User access tokens created by a GitHub App will expire after eight hours by default. Owners of GitHub Apps can optionally change the default expiration period for their user access tokens, or configure the tokens to never expire. For more information about configuring your GitHub App's user access tokens, see "Activating optional features for GitHub Apps."
