About enabling push protection
To enable push protection for a repository, you must first enable secret scanning. You can then enable push protection in the repository's "Code security and analysis" settings page following the steps outlined in this article.
You can additionally enable push protection for your own personal account, which prevents you from pushing secrets to any public repository on GitHub. For more information, see "Push protection for users."
If you're an organization owner, you can enable push protection for multiple repositories at a time using the GitHub-recommended security configuration. For more information, see "Applying the GitHub-recommended security configuration in your organization."
Organization owners, security managers, and repository administrators can also enable push protection for secret scanning via the API. For more information, see "REST API endpoints for repositories" and expand the "Properties of the security_and_analysis object" section.
