Piff follows Apple's own Face ID model exactly: a code (4-digit PIN or password) is always the base, biometrics is only an optional shortcut layered on top that falls back to the code if it fails. The code never leaves your device. Only a secure hash is kept, never sent to our servers.
- 4-digit PIN or password, your choice
- Face ID / Touch ID as an option, never the sole protection
- Automatic lock every time you return to the app
- Code stored only on your device, never on our servers
