SecureAuth Authenticator 2FA enhances your WordPress login security by requiring a time-based one-time password (TOTP) in addition to the regular username and password. The TOTP code is generated by an authenticator app on your mobile device, adding an extra layer of protection even if your password is compromised.
This plugin is lightweight, secure, and easy to use. It integrates directly into the user profile page to allow users to set up and manage their two-factor authentication with ease.
