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.
Open Mixin Settings
Tap your profile picture > Settings

Locate PIN Settings
Go to Account > Security > PIN

Enable Face ID Payment
Enter your PIN to confirm activation.

Set PIN Interval Time
You still need to enter your PIN periodically. Here, you can set the PIN interval time, with a minimum of 15 minutes and a maximum of 24 hours.

To turn off Face ID Payment, simply toggle the Face ID Payment switch off.

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.
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.
