Set screen lock

You can help secure your phone or tablet by setting a screen lock. 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 also unlock with your fingerprint or automatically unlock in trusted conditions.

Note: Android isn't the same on all devices. These instructions are for devices running Android 7.0 and up. Learn how to check your Android version.

Set up or change a screen lock

  1. Open your device's Settings app Settings.
  2. Under "Personal," tap Security.
  3. To change your screen lock's settings, next to "Screen lock," tap Settings Settings. Settings include automatic lock timing, Power button locking, and a lock screen message. Learn how to put information on your lock screen.
  4. To choose a kind of screen lock, tap Screen lock.
    • If you’ve already set a lock, you’ll need to enter your PIN, pattern, or password before you can choose a different lock.
    • Tap the screen lock option you’d like to use and follow the on-screen instructions.
