How to enable biometric fingerprint or face lock
Shield your household financial data when handing your phone to others.
Open Settings -> 'Account & Security'.
Toggle on 'Enable Biometric App Lock'.
Authenticate with your fingerprint or device facial recognition when prompted.
Set your auto-lock timeout preference (Immediately, after 1 minute, or after 5 minutes of inactivity).
Household Pro Tips:
