What happens if Face Unlock does not recognize me?

The phone falls back to the credential you set during registration. Enter your Pattern, PIN, or Password on the lock screen exactly as you confirmed it under Face unlock ➔ Enter the current Pattern, PIN or Password.

Can I remove my stored face data later?

Yes, open Settings ➔ Passwords & security ➔ Face unlock again and look for the option to delete the stored face model. You will need to confirm your PIN or password before MIUI removes the data.

Should I combine Face Unlock with a fingerprint?

Combining both gives you a faster unlock in good lighting and a reliable fallback when the camera struggles, for example in the dark or with a mask on. MIUI lets you keep fingerprint enrolled alongside Face unlock without turning either one off.

Xiaomi: Set Up Face Unlock

Xiaomi phones store a 2D scan of your face and use the front camera to unlock the screen without a fingerprint or PIN. Before you turn it on, MIUI itself warns that a photo of your face or someone who looks similar could sometimes trigger the same unlock. That trade-off between convenience and security is worth understanding before you register your face.

Set Up Face Unlock auf Xiaomi

Face Unlock on Xiaomi relies on a 2D scan captured by the front camera, not a depth sensor. That is why MIUI shows a warning before setup: a printed photo, a video, or a person with similar facial features can sometimes pass the check. This makes Face Unlock faster than typing a PIN, but weaker than fingerprint or pattern for anyone who needs strong protection against targeted unauthorized access.

To register your face, open Settings ➔ Passwords & security ➔ Face unlock. MIUI asks you to confirm your current Pattern, PIN, or Password first, since that credential still works as a fallback whenever the camera fails to recognize you. Tap Next and follow the on-screen guide to position your face inside the frame.

Once the scan is stored, you can choose whether Face Unlock also confirms app locks or payments, depending on what MIUI offers on your device. If you share your phone, work in low light often, or wear glasses and masks that change your appearance, fingerprint unlock or a pattern usually gives more reliable and more secure results.

Frequently asked questions

Yes, this is possible in some cases because Xiaomi phones use a 2D camera scan instead of a depth sensor. MIUI displays this warning directly inside Settings ➔ Passwords & security ➔ Face unlock before you register your face.
