Alternative Authentication Mechanisms

The Reserve Bank of India (RBI) has introduced a draft framework for “Alternative Authentication Mechanisms for Digital Payment Transactions”  to enhance the security of digital payments.

  • The RBI aims to improve the security of digital payment transactions by introducing alternative methods for authentication beyond the traditional SMS-based One-Time Password (OTP).

About Alternative Authentication Mechanisms:

  • All digital payment transactions must be authenticated using an additional factor of authentication (AFA), unless otherwise specified.
  • For all transactions other than card-present transactions, one of the authentication factors must be dynamically created. This means:
    • The factor is generated postinitiation of payment.
    • It is specific to the transaction and cannot be reused.
  • The framework is applicable to all Payment System Providers and Payment System Participants as defined in the Payment and Settlement Systems (PSS) Act, 2007.

Risk-Based Methodology:

  • Issuer Responsibilities: Banks and non-banks can use a risk-based approach to determine the appropriate AFA, considering factors like transaction value, origination channel, and customer risk profiles.
  • Customer Notification: Issuers are required to notify customers of eligible digital payment transactions almost instantly.

Categories of Authentication Factors:

  • Something the user knows: Examples include passwords, passphrases, and Personal Identification Numbers (PINs).
  • Something the user has: Includes hardware or software tokens.
  • Something the user is: Encompasses biometric identifiers such as fingerprints.
