Face recognition is less secure than Pattern, PIN, Iris, or Fingerprint.

Keep in mind your device can be unlocked by someone that looks similar to you (such as a twin).

If you are having trouble unlocking your device, you can use Find My Mobile and other methods (
"https://www.samsung.com/us/support/troubleshooting/TSG01001570/" ) to remotely unlock it.
