Introduction
Think of how you make an online payment today you enter your card details, get an OTP, and the transaction goes through.
With the announcement of Reserve Bank of India (Authentication mechanisms for digital payment transactions) Directions, 2025, All Payment System Providers and Payment System Participants, including banks and non-bank entities expected to transition to adopt newer guidelines to provide payment authentication.
From April 1, 2026, that process for payment authentication will go through transition. Customers may able to approve the same transaction with a biometric tap on your banking app and a dynamic passkey generated just for that moment.
For years, a single SMS-based OTP stood guard over billions of rupees driving across India’s digital economy. It was simple, familiar and it worked. It has its own limitations and risks. As digital volumes multiplied, so did fraud. SIM swaps, phishing links, and social engineering made static security the weakest point in an otherwise robust payments ecosystem.
The Reserve Bank of India has now drawn a line replacing a “one-size-fits-all” rule with a principles-led model of trust that adapts to risk, device, and context.
Why the Change Was Inevitable
The regulator’s objective is clear: reinforce trust in a system built for scale by introducing smarter, risk-sensitive authentication that keeps pace with digital adoption.

The Framework Explained: What RBI Now Requires
The Authentication Mechanisms for Digital Payment Transactions Directions, 2025 outline the new security baseline for every participant in India’s payments ecosystem.
- 1. Dynamic Authentication Factor
When a payment instrument (like a card or phone) isn’t near the acceptance device, at least one authentication layer must be dynamic and unique to that transaction. This means static OTPs may give way to cryptographic tokens, app-based approvals, or biometric confirmations.
- 2. Independent Layers of Proof
Each factor whether it’s something you know, have, or are must stand independently. If one gets compromised, the other remains secure.
- 3. Accessibility and Interoperability
Every authentication method must work seamlessly across different apps and payment systems, ensuring the ecosystem stays open and inclusive.
- 4. Risk-Based Enhancements
Banks and issuers can trigger additional checks depending on the risk profile based on factors like device behavior, location, or transaction pattern. Issuers may explore DigiLocker confirmations for high-risk cases.
- 5. Issuer Accountability
Institutions must verify the integrity of their authentication systems before launch, handle user data as per the Digital Personal Data Protection Act, 2023, and fully reimburse customers if any loss occurs due to non-compliance.
- 6. Cross-Border Card Transactions
From October 1, 2026, issuers must introduce risk-based validation for one-time overseas card payments, register Bank Identification Numbers (BINs) with networks, and monitor non-recurring, card-not-present transactions for potential risk.
From Compliance to Confidence: What’s Really Changing
Until now, security meant following standard practice of using OTP for all, regardless of risk.
Now, it is about providing security based on context using intelligence from the user’s device, behavior, and location to decide the right level of authentication.
In practice, this intends to makes payments safer and smoother. A familiar Face ID on your phone could double up as both possession and biometric proof fewer steps, stronger protection.
The regulation doesn’t discard OTPs; it evolves them. The goal is not to increase friction, but to make trust invisible yet reliable.
Impact Across the Ecosystem
- Banks and Payment Providers
Security is moving from a backend function to a user-facing differentiator. Banks will need to modernize token vaults, biometric gateways, and adaptive risk engines to deliver frictionless yet cryptographically strong authentication.
The shift also supports the Digital Personal Data Protection Act, 2023, embedding privacy-by-design into payment security. Banks that invest early in open APIs and contextual risk engines will enable safer, interoperable ecosystems.
- Fintechs and Global Players
This evolution aligns with global frameworks like Apple Pay, which rely heavily on biometric credentials and device-level encryption, positioning such models for wider acceptance in India’s new authentication landscape.
Domestic fintechs can follow suit by blending AI-led risk assessment, hardware-bound tokens, and biometric flows to create trust that persists across devices and channels.
- Consumers
Urban users will experience faster, biometric-led approvals, while rural users benefit from offline or proximity-based methods that ensure reliability even without stable networks. The outcome is a payment experience that feels secure, inclusive, and effortless.
Adoption Hurdles: Building Trust That Works Everywhere
Strategic Trade-offs for Banks and PSPs
As the new authentication mandate reshapes India’s payment landscape, banks and PSPs will need to balance innovation with usability, compliance with competitiveness, and security with scale. The coming phase will not just be about meeting regulatory deadlines it will be about making strategic choices that define customer trust, operational agility, and long-term differentiation.
1. Technology Investments vs. Experience Simplicity
Implementing device binding, biometrics, and real-time tokens will demand major upgrades. But if the new flows add friction, users may resist adoption. The key will be designing authentication that feels lightweight but powerful.
2. Interoperability vs. Differentiation
While ecosystem alignment is mandatory, banks can still differentiate by building faster, smarter, and more intuitive journeys. Security, when done right, becomes a selling point.
3. Short-Term Compliance vs. Long-Term Innovation
April 2026 (domestic) and October 2026 (cross-border) deadlines are immediate. But the true advantage will come from those who invest early in AI-driven fraud prevention and adaptive authentication models that turn compliance into capability
