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.
Features:
<ul>
<li>Adds a TOTP (Time-Based One-Time Password) field to the login form.</li>
<li>User-friendly 2FA setup available on each user’s profile page.</li>
<li>Generates secret keys and displays QR codes for scanning with mobile apps.</li>
<li>Compatible with apps like Google Authenticator, Microsoft Authenticator, and Authy.</li>
<li>Secure handling with nonce verification and input sanitization.</li>
<li>No external libraries required (except Google Chart API for QR code).</li>
</ul>

<h3>External services</h3>
This plugin uses a third-party service to generate QR codes during the TOTP authenticator app setup process.
<h4>QR Server API</h4>
When a user chooses the “Authenticator App” method during 2FA setup, the plugin generates a QR code image via the QR Server API. This QR code contains the TOTP secret URI (which includes the site name, user email, and secret key) so the user can scan it with their authenticator app.
<ul>
<li>What data is sent: A TOTP provisioning URI containing the site name, user email address, and a generated secret key.</li>
<li>When it is sent: Only once, when a user sets up TOTP-based two-factor authentication. No data is sent during normal login verification.</li>
