The full form of MPIN is ‘Mobile banking Personal Identification number’. It works as a password when you perform any transaction using mobile. It is a 4 digit (6 digits in some banks) secret code similar to the ATM PIN.
But it is different from the ATM PIN. The MPIN is used only when we transact through our mobile. Keep in mind, it is a sensitive code. You should keep it secret. Do not write it down anywhere.
Banks give this code to his customers when they register for mobile banking. You can also set your MPIN using UPI apps and USSD banking.
What is the Need
To keep the banking transaction secure need two-way authentication. As you get money from the ATM by using your ATM and PIN. Similarly, there should be 2 steps of authentication when you use the mobile transaction.
In the mobile banking, the first authentication is your mobile number. That is why you can do the mobile banking only through the registered mobile number.
The second authentication is your MPIN. You have to memorize it and only you should know it. It makes your mobile transaction secure. If there is not a MPIN, anyone can do the mobile transaction using your lost mobile.
You may be wondering that ATM PIN could be also used as the MPIN. However, RBI don’t want to expose the ATM pin. Also a different PINs would keep both the services independent.
