Device lock About fingerprint security
We strongly recommend locking your screen to help protect your phone. Your fingerprint sensor gives you a convenient unlocking option.
But there are a few things to keep in mind:
- A fingerprint can be less secure than a strong PIN, pattern, or password.
- A copy of your fingerprint could be used to unlock your phone. You leave fingerprints on many things you touch, including your phone.
- You'll be asked to add a backup PIN, pattern, or password. Remember your backup, because you'll need to use it sometimes, like after restarting your phone, or if your fingerprint isn't recognized.
- You can add up to 4 fingerprints.
Where your fingerprint data is stored
Your fingerprint data is stored securely and never leaves your phone. Your data is not shared with Google or apps on your phone. Learn more about how fingerprint data is secured.
