The new framework aims to bolster transaction security amid rising cyber frauds, while encouraging innovation in authentication methods
A New Era for Digital Payment Security
The Reserve Bank of India (RBI) has officially made two-factor authentication (2FA) mandatory for all domestic digital payments, effective April 1, 2026. This marks a significant step toward strengthening India’s digital payment infrastructure against growing cyber threats.
- The new guidelines are applicable to all payment service providers and ecosystem partners.
- While SMS-based OTP remains valid, the RBI is encouraging more dynamic and secure methods for authentication.
This directive is a follow-up to RBI’s 2024 proposal exploring alternative authentication methods, aimed at enhancing user safety and flexibility in a rapidly digitising economy.
What Counts as Two-Factor Authentication?
The RBI defines 2FA as requiring two of the following three authentication factors:
- Something the user knows – e.g., password, PIN, passphrase
- Something the user has – e.g., card, SMS OTP, hardware/software token
- Something the user is – e.g., fingerprint, facial recognition, Aadhaar biometrics
At least one of the two factors must be dynamically generated or proven—meaning it must be unique for each transaction (such as an OTP or token).
- DigiLocker may also be leveraged as a confirmation tool for high-risk transactions, adding another secure layer.
Emphasis on Innovation Over Prescription
While enforcing the 2FA rule, the RBI has avoided being overly prescriptive. It has not mandated any specific method, leaving room for technological innovation and context-specific adaptation.
- Biometrics, device-native authentication, and token-based verification are all allowed.
- The objective is to balance robust security with frictionless digital payment experiences.
This flexibility could encourage wider adoption of modern authentication tools, especially app-based biometrics and multi-device sign-ins.
Exemptions and International Payment Guidelines
The new rules are limited to domestic transactions. However, RBI has directed card issuers to prepare for international authentication requests:
- By October 1, 2026, systems must be in place to process and respond to foreign merchant authentication requests for international online card payments.
Notably, card-swipe transactions at POS terminals are exempt from this 2FA mandate, as the card’s physical presence serves as one layer of authentication.
Why This Matters: Rising Cyber Threats
The directive comes amid rising concerns over financial frauds and cybercrime in India’s booming digital payment space.
- As of the first nine months of FY25, Indians lost INR 107.21 Cr to cyber frauds, prompting the need for stronger transaction safeguards.
- By mandating dynamic authentication, RBI is attempting to cut down on fraudulent use of stolen credentials or OTP phishing.
What’s Next for Businesses & Consumers?
For banks, wallets, UPI apps, and payment aggregators, the priority will be:
- Upgrading infrastructure to support diverse 2FA methods
- Ensuring transaction-level uniqueness in at least one factor
- Preparing user interfaces to manage seamless, compliant experiences
For consumers, expect:
- A shift toward biometrics and app-based authorizations
- Possibly less dependence on SMS OTPs
- A more secure but familiar transaction flow
