1. Enter the correct password, PIN, pattern, fingerprint, or facial recognition.
2. If you forgot your password, try using any backup methods you may have set up.
3. Restart your device and try unlocking the screen again.
4. If all else fails, you may need to perform a factory reset on your device, but be aware that this will erase all data on the device.
