<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>
<li>Service provider: goQR.me / QR Server</li>
<li>Service URL: <a href="https://goqr.me/api/" rel="nofollow ugc">https://goqr.me/api/</a></li>
<li>Terms of service: <a href="https://goqr.me/api/doc/" rel="nofollow ugc">https://goqr.me/api/doc/</a></li>
