You need to re-authorize the auto-payment feature on GoTagihan if you change your GoPay PIN. To re-authorize your auto-payment, you do it through:

1. Notification that you’ll get if you change your GoPay PIN
2. Notification when you enter GoTagihan homepage
3. Clock icon on GoTagihan homepage, on the ‘Paused’ page

Then once you see your auto-payment list, choose ‘Reauthorize’ then enter your new GoPay PIN.
