The correct option is It lets scripts and tools authenticate to GitHub through the API or command line and you create it in settings with scopes that can be limited to a repository or an organization.

A personal access token supports noninteractive authentication for automation through the GitHub API and through Git over HTTPS. You create it in your account settings and can assign fine grained scopes so it only has the minimum access needed for a specific repository or an organization. This reduces risk compared to storing a basic password and it aligns with GitHub requirements because passwords are not accepted for API or Git operations.

It is a second factor that you enter after your password during sign in describes two factor authentication which is interactive and meant for human sign in. It is not a credential type that scripts can present automatically.

You can integrate GitHub Enterprise Server with your corporate directory and centrally manage repository access is about enterprise identity integration and access governance. That setup does not provide a secret for automation and it does not answer how scripts should authenticate to GitHub.

You can keep the account password in Google Cloud Secret Manager and reference it from your automation still relies on a basic password which GitHub does not accept for API or Git over HTTPS. A secret manager is useful for storage but the correct credential for automation should be a personal access token.
