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. WordPress.org +1
What This Plugin Does
Enables Two-Factor Authentication (2FA): After entering the username and password, users must input a one-time code from the Google Authenticator app or any TOTP-compatible app (e.g., Authy). easywp.com
Integrates With WordPress Login: Adds the additional authentication step directly on the wp-login.php screen for registered users. ChemiCloud
Per-User Configuration: Each user can enable or disable two-factor authentication from their profile settings, allowing flexible security control. easywp.com
QR Code Setup: Users scan a QR code in their profile with the Google Authenticator app to link the account. ChemiCloud
Time-Based One-Time Passwords (TOTP): Uses the established TOTP standard to generate six-digit codes that refresh every 30 seconds, improving login security. WordPress.org tiếng Việt
Works With Popular Authenticator Apps: Although called “Google Authenticator,” it’s compatible with any TOTP app (including Microsoft Authenticator, Authy, FreeOTP, etc.).
This plugin is ideal if you want to add a simple two-step verification system to WordPress without a full security suite — especially for admin users or key staff accounts. easywp.com
