MoMo Platform Upgrade
Single 4-Digit PIN Enhancement
What is Single 4-Digit PIN Enhancement?
The current dual-PIN structure which allows you to sign in with either a passcode or a pin will be replaced with a single 4-digit PIN that will be used for both account login and transaction authorization.
Why is this change being implemented?
The change is intended to simplify customer experience, reduce the burden of remembering multiple PINs, improve usability, and reduce system maintenance complexity while maintaining security through risk controls and biometric authentication.
Will I still need a separate Transaction PIN?
No. A single 4-digit PIN will be used for both login and transactions.
What are the PIN requirements?
The PIN must be 4 digits and cannot be sequential (1234/4321), identical (1111), or contain repeated patterns (1233, 2235, 5667).
Can I use Face ID or Fingerprint login?
Yes. Our customers can continue to use biometric authentication on supported devices.
What happens if I enter the wrong PIN?
You will be notified of the remaining attempts. Once the retry limit is reached, access will be temporarily restricted. If this happens during the process of upgrading to the new app, please contact our customer support team by calling 671.
What happens if I change my phone's biometric settings?
Biometric login will be disabled, and you will be required to authenticate using your PIN.
What if I forget my PIN?
You can reset your PIN through the available PIN reset process, including assisted support where applicable. If this happens during the process of upgrading to the new app, please contact our customer support team by calling 671.
