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 and leaves out passwords, 2FA secrets, API-key hashes, the SMTP password, signing secrets and webhook URLs, so it can be shared; 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, and it stays private.
