What is a Mobile Personal Identification Number (MPIN) and how is it used in IMPS transactions?

A Mobile Personal Identification Number (MPIN) is a unique numeric password used for authentication in IMPS (Immediate Payment Service) transactions in India. It acts as a secondfactor authentication method to ensure the security of mobilebased financial transactions.

When you register for IMPS services through your bank, you will be assigned an MPIN. The MPIN is usually a four or sixdigit numeric code that you set during the registration process or provided by your bank. It is meant to be kept confidential and known only to you.

The MPIN is used in the following ways during IMPS transactions:

1. Mobile Banking Login: When you access your mobile banking application or platform to perform an IMPS transaction, you will be prompted to enter your MPIN as a part of the login process. This ensures that only authorized individuals with knowledge of the MPIN can access the mobile banking interface.

2. Transaction Authentication: During the initiation of an IMPS transaction, your mobile banking application or platform will require you to enter your MPIN to authorize the transaction. This acts as an additional layer of security to ensure that only the account holder can initiate transactions.

3. Resetting or Changing MPIN: If you need to reset or change your MPIN, you will typically be required to provide certain identification details, answer security questions, or go through other authentication processes to verify your identity before setting a new MPIN.

The MPIN adds an extra level of security to IMPS transactions by requiring a personal identification number in addition to the regular login credentials. It helps prevent unauthorized access to your mobile banking account and protects against unauthorized transactions.

It's important to keep your MPIN confidential and avoid sharing it with anyone. Memorize your MPIN and avoid using easily guessable or common numbers. Regularly monitor your bank account for any unauthorized transactions and immediately report any suspicious activity to your bank.

Please note that the exact process and usage of MPIN may vary slightly depending on the bank and the specific mobile banking application or platform you are using. For specific details and guidance related to MPIN usage in your IMPS transactions, it's recommended to refer to your bank's official documentation, contact their customer support, or visit the bank branch.
