Basics of MPIN Number

MPIN, short for Mobile Personal Identification Number, is a 4 to 6-digit code that provides secure access to your mobile banking applications and enables transactions. Setting an MPIN essentially locks your banking app and creates an additional layer of security beyond your phone password or lock. Before initiating sensitive transactions like fund transfers or bill payments through your bank's mobile app, you will be prompted to enter your unique MPIN as authentication. This prevents unauthorized access and verifies your identity for the mobile transaction. MPINs prevent misuse of your account in case others lose or access your phone. It is important to memorize your MPIN and not store it on your phone for security reasons. MPINs thus enable safe mobile banking by providing user verification through a confidential PIN code. Most banks now require users to set an MPIN when activating mobile banking services. Now that you know What is MPIN, let's understand what is mobile banking in the next section.

Significance of MPIN in UPI

MPIN plays a vital role in UPI and mobile payments. They make your transaction secure and more convenient for you. Here are some advantages of MPIN in UPI:
