The 90-day authentication code that expired is just a normal thing when it comes to your GCash account. This happens to all the GCash users and there's nothing to worry about. I think personally, this is just an additional security measure of GCash for its users to update their code once every 3 months which I think is a good one.


After 3 months, you are required for re-authentication. All you need to do, is to enter a new code in the app. And we will do that process for this tutorial.


Here are the steps to re-authenticate your GCash account after the 90-day authentication code already expired.


✅ Re-enter your GCash-registered number and press NEXT button to proceed.

✅ A 6-digit OTP (one-time pin) number will be sent to your GCash-registered phone number. Enter

the number correctly and press the Submit button to confirm.

✅ After successfully entering the 6-digit OTP, you will now need to type your 4-digit MPIN.

✅ When done, you are now inside your GCash account. You have successfully re-authenticated and opened your account.
