To change your UPI PIN, follow these steps within your UPI-enabled application:
- Navigate to the 'Payment Settings' or 'Profile' section and select the linked bank account.
- Choose the 'Change UPI PIN' option.
- Enter your existing UPI PIN for authentication.
- Set a new 4 or 6-digit UPI PIN and re-enter it to confirm.
If you have forgotten your current PIN, use the 'Forgot UPI PIN' or 'Reset PIN' option, which requires your debit card details or Aadhaar-based verification to set a new one.
