Details

The appearance and security policy of the credential store depends on your version of git, your operating system, your R frontend and which credential_helper is used. On Windows and MacOS the credentials are stored in the system password manager by default.

It should be assumed that reading credentials always involves user interaction. The user may be asked to unlock the system keychain or enter new credentials. In reality, user interaction is usually only required on the first authentication attempt, but the security policy of most credential helpers prevent you from programmatically testing if the credentials are already unlocked.
