1. Introduction

Explains the purpose of the Directions: to mandate two-factor authentication (2FA) for digital payments and to enable alternative, technology-driven authentication methods beyond SMS-based OTP.

2. Effective Date

Specifies that all payment system providers and participants must comply by April 1, 2026, unless noted otherwise.

3. Applicability

Clarifies that the Directions apply to:

  • All domestic digital payment transactions (unless exempted).
  • All banks and non-bank entities acting as payment system providers or participants.

4. Definitions

Defines key terms used throughout the document, including:

  • AuthenticationCard Present/Not Present (CNP) transactions, Cross-border CNPDigital Payment TransactionFactor of Authentication, and Issuer.

5. Principles for Authentication of Digital Payment Transactions

Outlines the core requirements for any authentication mechanism:

  • Two distinct factors of authentication as listed in the Definitions.
  • At least one dynamic factor, unique to each transaction.
  • Robustness, ensuring compromise of one factor does not weaken the other.
  • Exemptions to 2FA are detailed in Annexure-1.

6. Interoperability / Open Access

Mandates that authentication or tokenisation services must be accessible across all applications, channels and token storage methods in a given operating environment, ensuring a level playing field for all participants.

7. Risk-Based Approach

Allows issuers to apply additional security checks—such as behavioural analysis, device attributes and transaction history—for high-risk transactions and suggests using platforms like DigiLocker for notification/confirmation.

8. Responsibility of the Issuer

Specifies issuer obligations:

  • Ensure integrity and robustness of their authentication systems.
  • Fully compensate customers for any losses arising from non-compliance.
  • Adhere to the Digital Personal Data Protection Act, 2023.

9. Cross-Border Transactions

Extends similar authentication requirements to online international card transactions using cards issued in India, aligning with prior RBI policy on cross-border safety.

10. Repeal

States that any previously issued directions on authentication for digital payments are repealed upon the effective date.

Annexures

  • Annexure-1: Lists exemptions to the two-factor authentication requirement.
