Your MPIN (Mobile Personal Identification Number) is your nominated 4-digit passcode that acts as your password to your GCash account, so we recommend that you regularly update it.
Note: The MPIN you use on Messenger is the same MPIN you will use to access the GCash App.
To change your MPIN (or if you forgot your MPIN), open the Messenger app and select Money.
Under Your Account, select Manage.
Then, select Change PIN.
Enter your new MPIN and re-enter to confirm it.
Then, enter your Facebook password.
Once successful, you will receive an SMS from 2882.
