Quick tip: Don’t mix them up — each serves a different purpose.

Real-life example

Rita uses her bank’s mobile app. She sets her MPIN as “753201”. One evening she transfers ₹5,000 to her friend via IMPS. The app asks for MPIN: she enters “753201” and the transfer goes through. Later she forgets the code, uses “Forgot MPIN” in app and resets it via OTP. In short: MPIN = your mobile-banking key.

1. Open your bank’s mobile banking app and log in.
2. Go to “Settings” or “Profile” and select “Set/Reset MPIN”.
3. Verify with OTP sent to your registered mobile number.
