How to Use Biometric Login

Safe supports fingerprint and face unlock — and on Windows, Windows Hello — so you don't have to type your master password every time.

Setup

Android Biometry settings screen

Go to Settings → Biometry. Turn on the Biometric login toggle and confirm when prompted by your system.

Note: Biometrics must be configured in your phone's system settings first. The method set there (fingerprint or face) will be used automatically when you choose the default biometric option in Safe.

Usage

Close and reopen Safe — the unlock screen will prompt for your biometric. If recognition fails, tap the password field at the bottom of the screen and enter your master password.

Important: Remember your master password even when using biometric login. If you forget it, you will not be able to restore access to your data.

Troubleshooting

Biometric login doesn't work?

Make sure biometrics are enabled in your phone's system settings
Check that Biometric login is on in Settings → Biometry
Turn it off, restart the app, then turn it back on and complete setup again

Note: Biometric recognition may fail due to dirty sensors, poor lighting, or changes in appearance (cuts, makeup, glasses, etc.).

Setup

Face ID settings in Safe

Go to Settings → Biometry. Turn on Face ID (or Touch ID on older devices). Restart the app and confirm access when prompted at login.

Note: Face ID / Touch ID must be configured in your iPhone's Settings → Face ID & Passcode first.

Usage

Next time you open Safe, Face ID or Touch ID will activate automatically on the unlock screen.

Important: Remember your master password even when using Face ID or Touch ID. If you forget it, you will not be able to restore access to your data.

Troubleshooting

Can't activate Face ID / Touch ID in Settings?

Make sure Face ID / Touch ID is fully configured in iPhone Settings → Face ID & Passcode
Confirm your Premium subscription is active — biometric login requires Premium
Try restarting the device
Disable Face ID in iPhone Settings, then re-enable it

Face ID doesn't activate on the unlock screen?

You may have changed a phone security setting — enter your master password once to reactivate biometrics
If your free trial has expired, upgrade to Premium to continue using biometric login

Setup

Authentication settings on Windows

Open Options → Authentication. You'll see four controls:

Fast unlock — log in by typing only the first few symbols of your master password (e.g. the first 4) instead of the full one
Login with Windows Hello — use fingerprint, face, or PIN via Windows Hello to unlock Safe
Auto-start Windows Hello — show the Windows Hello prompt automatically when you open Safe
Require password every — periodically force re-entry of the full master password (default: 15 days) as a safety net

Note: Windows Hello must be configured in Windows first — Windows Settings → Accounts → Sign-in options. If Login with Windows Hello is grayed out, that's why.

Usage

With Auto-start Windows Hello on, opening Safe triggers the Windows Hello prompt (fingerprint, face, or PIN) right away. Authenticate and you're in.

If you prefer to type the password — or if Windows Hello fails — click the password field on the unlock screen and enter your master password (or the fast-unlock prefix, if configured).

Important: Remember your master password. Windows Hello is a convenience layer — the full password is still required after the Require password every interval and on first launch after reinstall.

Troubleshooting

"Login with Windows Hello" is grayed out? — Windows Hello isn't set up at the OS level. Open Windows Settings → Accounts → Sign-in options and configure a method (fingerprint, face, or PIN).

Windows Hello prompt doesn't appear when I open Safe? — Check that Auto-start Windows Hello is on in Options → Authentication.

Need to re-enter the full password unexpectedly? — The interval you set under Require password every has elapsed. Type the full password once and the timer resets.
