The PIN code in Surf consists of 6 digits and is an additional security measure that guarantees the safety of your funds even if someone connects remotely to your device and wants to make a transaction to the address he wants. If he doesn't know the PIN code, he will fail.

You can use face recognition or fingerprint to avoid having to enter a PIN code. Whether these functions are available in the settings depends on your device. If your device does not support these functions, you cannot enable them in Surf. 

To enable the fingerprint or face recognition unlock feature:

  1. At the top of the home screen, tap the nut icon.

  1. Tap Safety protection.

  1. Tap Lock method.

  1. Select one of the unlock options depending on the device you are using:

  • If you have a smartphone with a fingerprint scanner, select Use fingerprint unlock, then enter your pin code and place your finger on the fingerprint scanner on your device to complete the setup.

  • If your smartphone supports face recognition, select Use face unlock, then point the front camera of the device at your face to complete the setup.
