Keep in mind that:

• If your phone has been locked for more than 4 hours, face matching won't work until you first unlock with another method.
• Looking at your phone can unlock it, even when you don't intend to.
• Your phone can be unlocked by someone who looks a lot like you.
• Your phone can be unlocked by someone else if it's held up to your face while your eyes are open. Keep your phone in a safe place. To prepare for unsafe situations, you can turn on lockdown.

1. Go to Settings > Security and privacy > Device unlock > Face and fingerprint unlock.
2. Unlock your phone and tap Face unlock.
