Also known as: 2FA, MFA
A second login step beyond a password, usually a time-based code generated by an app. On Usenet services it normally guards only the billing or control panel, because NNTP itself has no standard second-factor mechanism and newsreaders authenticate with a plain username and password over TLS. Many providers therefore issue a separate NNTP password so one leak does not expose the account portal.
