Enhanced Security for Digital Payments
The Reserve Bank of India's (RBI) new rules requiring two-factor authentication for digital payments came into effect on Wednesday, April 2, 2026.
This move aims to significantly curb digital fraud by adding a necessary layer of security. It is intended to protect account holders from unauthorized access to their funds.
Two-Factor Authentication Explained
Under the RBI's (Authentication Mechanisms for Digital Payment Transactions) Directions, 2025, providers must use at least two authentication factors.
This includes banks and non-bank entities. It also impacts UPI transactions, according to industry sources.
Authentication Options
Acceptable authentication methods include:
- Password
- SMS-based OTP
- Passphrase
- PIN
- Software token
- Fingerprint (or other biometrics)
The central bank requires that service providers offer customers a choice of authentication factors.
Exemptions and Initial Scope
The two-factor authentication is not applicable to all transactions. Exemptions include small value contactless card payments, recurring electronic mandates (except the first), and some prepaid instruments.
Initially, the new rule will cover domestic transactions only.
System Upgrades and Additional Checks
Banks and payment service providers are actively upgrading their systems. These upgrades will support two-factor authentication and add app and device-level safeguards.
Banks and payment service providers may also undertake extra checks beyond the mandated two-factor authentication to enhance security.
Validating Cross-Border Transactions
The RBI has also instructed card issuers to implement a mechanism. This mechanism will validate non-recurring, cross-border card not present (CNP) transactions.
This is for situations where authentication is requested by an overseas merchant or acquirer. This must be in place by October 1, 2026.
Expert Opinion
"OTPs have become deeply embedded in India’s financial ecosystem. But they only aim at establishing possession. If someone gains access to your SIM or tricks you into revealing it, it gives easy access to the fraudster to take control of your sensitive assets."
"Trust has to be established through context, by combining who you are, what you know, and what you have, and evaluating these signals in real time," said Anil Tadimeti, director, strategy & regulatory affairs, Bureau.
What to Watch Next
Keep an eye on updates from your bank and payment service providers regarding their specific implementation of two-factor authentication. Also, watch for any further announcements from the RBI regarding the scope and application of these new rules.
