Note: Updating credentials from the macOS Keychain only applies to users who manually configured a personal access token using the osxkeychain helper that is built-in to macOS.
We recommend you either configure SSH or upgrade to the Git Credential Manager (GCM) instead. GCM can manage authentication on your behalf (no more manual personal access tokens) including 2FA (two-factor auth).
When Git prompts you for your password, enter your personal access token. Alternatively, you can use a credential helper like Git Credential Manager. Password-based authentication for Git has been removed in favor of more secure authentication methods. For more information, see "Managing your personal access tokens."
Updating your credentials via Keychain Access
- Click on the Spotlight icon (magnifying glass) on the right side of the menu bar.
- Type
Keychain Access, then press the Enter key to launch the app. - In Keychain Access, search for
github.com. - Find the "Internet password" entry for
github.com. - Edit or delete the entry accordingly.
Deleting your credentials via the command line
Through the command line, you can use the credential helper directly to erase the keychain entry.
$ git credential-osxkeychain erase
host=github.com
protocol=https
> [Press Return]
If it's successful, nothing will print out. To test that it works, try and clone a private repository from GitHub.com. If you are prompted for a password, the keychain entry was deleted.
