The Xiaomi device has a fingerprint sensor that we can set up to unlock the phone, authorize purchases, or log in. It doesn't matter which fingerprint we add; if an unlock method has been previously set by pattern, PIN, or password entry, we will need to know the unlock method prior to setup.
Note: To activate the unlock method by fingerprint, a display lock via PIN, password or pattern must be set up.
- Open the Settings
- Tap on Passwords & security
- Tap on Fingerprint unlock
- Enter the current pattern, PIN or password
- Place the finger on the fingerprint sensor and follow the instructions on screen
