How to set up an UPI password?

To set up a UPI PIN, open the UPI payment application (like Paytm) on your phone. Navigate to the "UPI & Linked Bank Accounts" or "UPI & Payment Settings" section. Select the bank account and choose the "Set PIN" option. You will generally need to provide the last 6 digits of your debit card number and its expiry date or use your Aadhaar number for verification. After OTP validation, you can create and confirm your 4- or 6-digit UPI PIN.
