 Authentication
 --------------
 
-**Password-based authentication** will fail if you have two-factor authentication enabled, and will `be deprecated <https://github.blog/2023-03-09-raising-the-bar-for-software-security-github-2fa-begins-march-13/>`_ by 2023 EOY.
+GitHub requires token-based authentication for API access. Password authentication was `removed in November 2020 <https://developer.github.com/changes/2020-02-14-deprecating-password-auth/>`_.
 
-``--username`` is used for basic password authentication and separate from the positional argument ``USER``, which specifies the user account you wish to back up.
+The positional argument ``USER`` specifies the user or organization account you wish to back up.
 
-**Classic tokens** are `slightly less secure <https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens#personal-access-tokens-classic>`_ as they provide very coarse-grained permissions.
+**Fine-grained tokens** (``-f TOKEN_FINE``) are recommended for most use cases, especially long-running backups (e.g. cron jobs), as they provide precise permission control.
 
-If you need authentication for long-running backups (e.g. for a cron job) it is recommended to use **fine-grained personal access token** ``-f TOKEN_FINE``.
