    Select a secure lock method

    Select either PIN or Password from the list of options. Avoid Pattern or Swipe, as these are vulnerable to observation and physical residue tracking.

    Note: A Password allows for alphanumeric characters, offering significantly higher security than a numeric PIN.

    Set your new credential

    Enter a complex, unique sequence that does not correlate with birthdays or simple patterns. Confirm the new PIN or password by entering it a second time when prompted.

    Note: Ensure your credential is not reused from other sensitive accounts.

    Enable biometric authentication

    Return to the Device unlock menu and select Fingerprint or Face Unlock if your hardware supports it. These serve as a secondary layer of convenience for daily use while maintaining your primary secure credential as a backup.

    Note: Always maintain a strong primary PIN or password for cases where biometric sensors fail.
