The HTC U11 has a fingerprint scanner. If you didn't set it up during the initial set up, you should do it now.
- Go to Settings > Fingerprint scanner
- Tap Add fingerprint > Next
- If you haven’t already set up a lock screen pattern, PIN, or password, you’ll be asked to set one up
- Tap Start
- Choose which finger to use, touch the scanner until it vibrates, then lift your finger
- Touch the scanner until the fingerprint has been successfully recorded
- After you’ve successfully recorded your fingerprint, tap Done
