GitHub Personal Access Token

Description

General

• Documentation: https://docs.github.com/en/rest/overview/other-authentication-methods#via-oauth-and-personal-access-tokens

• Summary: GitHub is a code hosting platform for version control and collaboration. Personal Access Tokens (PATs) are used to authenticate API requests on behalf of a GitHub user. These tokens are issued by a user and can be configured with specific scopes to limit their permissions. GitGuardian supports both the old and new formats for these tokens. This detector group focuses on identifying classic GitHub Personal Access Tokens.

• IPs allowlist: No

• Scopes: Personal Access Tokens can be configured with a variety of scopes and permissions, such as read/write access to repositories, user data, or organization resources. For a full list of available scopes, refer to the GitHub documentation.

Revoke the secret

Tokens can be revoked from the access tokens panel. Navigate to the "Personal access tokens" section and delete the token to revoke access.

Check for suspicious activity

There is no way to check the exact last API calls made with a token. However, GitHub provides security logs to review account activity and detect suspicious behavior.
