If you want to update or reset your Google Pay PIN, you may do so in the PayPal app or on paypal.com. In the PayPal app, tap the Settings gear icon, then Google Pay, then in-store PIN. On paypal.com, log in to your account and click the Settings gear icon. Then, under the security tab, select Update next to “Google Pay PIN." Automatic top up is only applicable for in-store purchases.
