A UPI PIN (Unified Payments Interface Personal Identification Number) is a secure 4 or 6-digit code you create to authorise all bank transactions on a UPI-enabled application. It acts as a crucial security measure, verifying your identity before any payment is processed. You must enter this unique PIN to confirm money transfers, ensuring a secure and reliable experience directly from your linked bank account. You will set this PIN when you first link a bank account to the app, usually by verifying details with your debit or Aadhaar card.
