Your PIN works like a PIN on any other debit card (except that your Jawnt card can’t be used at ATMs), so from time to time you may need to reset it.
Resetting your PIN
In the card management area, look above the picture of the physical card for the “Manage Card” button.
Select “Manage PIN”.
Enter your current PIN.
Enter and re-enter your new PIN.
The PIN will be updated immediately.
