What is a 6-digit UPI PIN?

A 6-digit UPI PIN is a secure personal identification number used to authorize financial transactions on the Unified Payments Interface platform. It acts as a digital password that ensures only the account holder can initiate fund transfers or payments. While some banks use a 4-digit PIN, many opt for 6 digits to provide an enhanced layer of security with over one million possible combinations. Users set this unique code during their first-time registration by verifying their debit card or Aadhaar details. It must be kept confidential to prevent unauthorized access.
