WP-OTP is a free WordPress plugin that introduces an essential layer of security through Two-Factor Authentication (2FA) using One Time Passwords (OTP). Designed to protect user logins, it allows users to enable 2FA easily via their profile page by scanning a QR Code or entering a secret key into any OTP generator app. Once set up, logging in requires an OTP, adding significant security to WordPress sites.

One of the standout features of WP-OTP is its stealth mode, which conceals the OTP entry field, making the login process appear seamless. The plugin offers a variety of configuration options, including the ability to customize login form text and set expiration windows for OTP codes. It’s open-source and continually developed, providing users with flexibility and control over their authentication processes.
