Two-factor authentication (TOTP)
Add a second factor: your password plus a 6-digit code from an authenticator app (Aegis, 1Password, Google Authenticator…). Recovery codes cover a lost phone.
Backups
Everything you own, in one click. The JSON export covers every table, with password hashes, two-factor secrets, API-key hashes, signing secrets and webhook URLs left out (after restoring it on a fresh install, re-enter your webhook URLs, as you do signing secrets); the database file is the rawest possible backup on SQLite installs. Administrators only.
