What happens if a user forgets his UPI PIN?

If a user forgets their UPI PIN, they can reset it immediately using the relevant UPI-enabled application. To reset the PIN, the user will typically need to verify their identity using their debit card details or, in some cases, their Aadhaar card details linked to the bank account. For example, if using Paytm, a user can select their bank under UPI & Payment Settings, choose 'Reset PIN,' and verify with their debit or Aadhaar card to create a new PIN.
