# How to Enable/Disable Pay With Face ID?

Mixin supports Face ID Payment, allowing you to use Face ID instead of entering your PIN for a more efficient experience. However, Face ID cannot help you recover your PIN, and you will still need to enter your PIN periodically to ensure its validity.

### Enabling Face ID Payment
1. Open Mixin Settings
Tap your **profile picture > Settings**

### Frequently Asked Questions
1. Why can’t I enable Face ID Payment on my device?

Mixin’s Face ID Payment feature relies on your device’s built-in Face ID or fingerprint authentication. If this feature is not enabled on your device, Mixin cannot activate Face ID Payment.

2. Why do I still need to enter my PIN after enabling Face ID Payment?
For security reasons, Face ID Payment has an expiration period. Once the interval time is exceeded, you must re-enter your PIN.

For example, if you set the PIN interval to 2 hours, you can use Face ID for transactions within 2 hours after entering your PIN. However, after 2 hours, Mixin will require you to enter your PIN again to confirm any transactions.
