Technically, Cash App PIN is a security feature to ensure the complete safety of your Cash App payment account. According to the settings, users have to enter a PIN or scan a thumb to complete a transaction. This security feature can’t be skipped in any condition. Until and unless one enters the PIN or scans a thumb, payment does not complete. In case you have forgotten your PIN then go to your profile section and change your PIN.
