The face unlock on the Redmi Pad Pro is a security feature that uses facial recognition technology to unlock your tablet. You cansimply look at thefront-facing camera without needing to enter passwords, which enhances convenience. To set the face unlock on the tablet, please refer to the following steps: 1. Open [Settings]; 2. Enter [Face data & screen lock]; 3. Tap [Face unlock]; 4. Tap [Next]; 5. Before enabling face unlock, set a screen lock first. You can choose [Pattern], [PIN], or [Password] as you prefer; 6. After setting up, tap [Start] to add face data; 7. Keep your face inside the frame shown on the screen. Once registration is completed, you can unlock the tablet using your face data now. Note: Face unlock is less secure than a PIN, password, or pattern. Your device might be unlocked with your photo, as well as by people or objects with a similar appearance.
