Set screen lock on an Android device

You can set up a screen lock to help secure your Android phone or tablet. Each time you turn on your device or wake up the screen, you’ll be asked to unlock your device, usually with a PIN, pattern, or password. On some devices, you can unlock with your fingerprint.

Important: Some of these steps work only on Android 10 and up. Learn how to check your Android version.

Screen lock options

You might find different options depending on your phone. For more info about screen lock for your device, go to the manufacturer’s support site.

No lock

  • None: Your phone stays unlocked. This gives no protection, but you can get to your Home screen quickly.
  • Swipe: Swipe your finger across your screen. This gives no protection, but you can get to your Home screen quickly.

Standard locks

  • Pattern: Draw a simple pattern with your finger.
  • PIN: Enter 4 or more numbers. Longer PINs tend to be more secure.
  • Password: Enter 4 or more letters or numbers. A strong password is the most secure screen lock option.
