GitHub secret scanning protects users by searching repositories for known types of secrets. By identifying and flagging these secrets, our scans help prevent data leaks and fraud.
We have partnered with Chief Tools to scan for their tokens and help secure our mutual users on public repositories. Chief Tools tokens allow users to access the Chief Tools API and perform automated actions on behalf of the user that created the token. GitHub will forward access tokens found in public repositories to Chief Tools, who will immediately revoke the token and email the owner of the leaked token with instructions on next what to do next. You can read more information about Chief Tools tokens here.
GitHub Advanced Security customers can also scan for Chief Tools tokens and block them from entering their private and public repositories with push protection.
