Google Authenticator for WordPress is a security plugin that enables two-factor authentication (2FA) for your website’s login system. By requiring users to enter a time-based one-time password (TOTP) generated by an authenticator app (such as Google Authenticator on mobile devices), this plugin adds a powerful extra layer of protection beyond the standard username and password. This helps prevent unauthorized access, brute-force attacks, and account compromises — particularly for administrator and other sensitive accounts.
