When a token has been revoked, it can no longer be used to authenticate Git and API requests.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 Server 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."
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 your authorized integrations" and "Reviewing your authorized applications (OAuth)."
Once an authorization is revoked, any tokens associated with the authorization will be revoked as well. To re-authorize an application, follow the instructions from the third-party application or website to connect your account on your GitHub Enterprise Server instance 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 "Delete an app authorization."
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-to-server tokens created by a GitHub App will expire after eight hours by default. Owners of GitHub Apps can configure their apps so that user-to-server tokens do not expire. For more information about changing how your GitHub App's user-to-server tokens behave, see "Activating optional features for apps."
