About fingerprint security
We recommend that you lock the screen to help protect your device. The fingerprint sensor gives you easy screen lock options.

However, there are a few things to keep in mind:

Fingerprints may be less secure than PINs, patterns, or passwords.
A copy of the fingerprint can be used to unlock the phone. You leave your fingerprints on many of the things you touch, including the phone.
You will be asked to add a PIN, pattern, or backup password. Remember these backup PINs, patterns, and passwords because sometimes you will need them, such as after restarting the device or if the fingerprint is not recognized.
Fingerprint data storage
Your fingerprint data is stored securely and is only on the device. Data will not be shared to Google or apps on the device. Learn more about securing fingerprint data.
