<h3>Data Handling Summary</h3>

When CAPTCHA is enabled: Only the specific provider you choose receives verification data. Data is not shared between providers or stored by Guard Dog beyond the verification process.
When 2FA is disabled: No external data transmission occurs.
When 2FA is enabled: 
– All TOTP operations (code generation, verification) happen locally on your server 
– No data is transmitted to external services for 2FA functionality 
– Authenticator apps only receive the initial setup QR code or secret key 
– Recovery codes are generated locally and stored securely
User control: Users can choose which CAPTCHA provider to use, or disable CAPTCHA entirely. 2FA can be enabled/disabled per user, and users can choose their preferred authenticator app. All security features are optional and configurable.
