 - Social login users are auto-verified (trusted from provider)
 - Social accounts can only be linked to users with verified emails
 
+When `AUTH_ENABLE_TWO_FACTOR=true`, authenticated users can enroll an authenticator
+and manage recovery codes from `/profile`. Existing password and social logins are
+both held at the two-factor challenge until a valid TOTP or one-time recovery code is
+provided.
+
+Set both `AUTH_ENABLE_TWO_FACTOR=true` and `AUTH_REQUIRE_TWO_FACTOR=true` to
+require every authenticated user to complete enrollment before accessing
+protected web pages or authenticated API endpoints. Enrollment, email
+verification, and logout routes remain available while setup is pending.
+
 See `config/auth-ui.php` for all available options including page titles, icons, legal links, and social provider configuration.
