Rename Face Data auf Xiaomi
Xiaomi phones let you store several face profiles for Face unlock, for instance one for your normal look and another for glasses or a beard. MIUI gives each entry a generic label such as 'Face data 1', which makes it hard to tell which profile belongs to which appearance once more than one is saved.
Renaming a face profile does not change how Face unlock recognizes you. It only updates the label shown in the security settings, so you can identify and manage each entry correctly, especially before deleting one of them.
How to rename a face profile
Open Settings ➔ Passwords & security ➔ Face unlock. Confirm your identity by entering your current Pattern, PIN or Password.
Select the Face data entry you want to edit, enter a new name and tap Save.
If the Face unlock entry is missing, your device might not support face recognition, or no face profile has been set up yet. Set up a face profile first before trying to rename it.
