AFA (Additional Factor Authentication)

byPaytm Editorial TeamLast Updated: July 31, 2025

Meaning

The full form of AFA is Additional Factor Authentication. It is a security feature used in digital banking and online transactions to provide an extra layer of protection.

How It Works

AFA typically combines two types of user authentication:

  1. Something the user knows (like a password or UPI PIN)
  2. Something the user receives (like an OTP on their mobile)

This two-step process ensures that even if one factor is compromised, the transaction remains secure.

Importance

AFA is mandatory in many financial systems in India, including UPI, card transactions, and online banking. It helps reduce fraud and unauthorized access by verifying the identity of the user more thoroughly.
