India's digital payments ecosystem is about to get a significant security upgrade. The Reserve Bank of India has introduced a new set of rules that will reshape how millions of Indians transact online — whether through UPI, debit or credit cards, or digital wallets. The changes come into effect on 1 April 2026, and while they may add a brief extra step to everyday payments, the underlying purpose is straightforward: make digital transactions safer and drive down fraud.

 

The End of OTP-Only Authentication

The most consequential change under the new RBI framework is the move to mandatory two-factor authentication, commonly known as 2FA, for all digital transactions. Until now, a one-time password sent to a registered mobile number was sufficient to authorise most online payments. That single-step system is now being phased out as the primary security mechanism.

 

Going forward, every payment will require at least two independent forms of verification. These could be any combination of a PIN, password, biometric identifier such as a fingerprint or face scan, or a hardware or software token. The core principle is that no single credential  however convenient — will be enough on its own to approve a transaction.

 

The reason for this shift is the growing sophistication of digital fraud. OTP-based systems have become increasingly vulnerable to phishing attacks, where users are tricked into sharing their codes, and SIM swap scams, where fraudsters hijack a victim's mobile number to intercept messages. By requiring a second independent layer of verification, the RBI aims to close these loopholes and significantly reduce the scope for unauthorised access.

 

What Users Can Expect Day to Day

For most users, the practical change will be a slightly longer payment process as the additional verification step is completed. However, the system is designed to be intelligent rather than uniformly disruptive. Risk-based authentication will be built into the framework, meaning that the level of scrutiny applied to a transaction will depend on factors such as the size of the payment, the type of transaction, and the user's behaviour patterns.

 

Routine payments made on trusted, familiar devices may proceed relatively smoothly, as the system will recognise established patterns. However, transactions initiated from new devices, unusually large payments, or activity that deviates from a user's normal behaviour are likely to trigger more rigorous verification checks. The intent is to balance security with convenience — applying friction where the risk is highest, while keeping everyday transactions reasonably fluid.

 

Banks Will Be Held Accountable

One of the more significant structural shifts in the new rules is the formal assignment of responsibility to banks and payment platforms. Financial institutions will now be required to comply with the updated security standards, and if a fraud incident occurs as a result of a system-level failure on the bank's part, the institution may be held liable to compensate the affected user. This is expected to result in faster resolution of fraud complaints and places a stronger obligation on banks to proactively secure their payment infrastructure, rather than treating security as a secondary concern.

 

International Transactions in Scope

The RBI's new authentication standards will not be limited to domestic transactions. Cross-border card payments will also fall under a similar two-factor framework, acknowledging that international transactions carry their own set of fraud risks. Full implementation for international payments is expected to be completed by October 2026, giving banks and payment networks a transition window to align their systems with the new requirements.

 

The Bigger Picture

India's digital payments infrastructure has grown at a remarkable pace over the past decade, with UPI alone processing billions of transactions every month. But that scale also makes the ecosystem an attractive target for cybercriminals. The RBI's updated rules reflect a recognition that the security architecture underpinning these systems needs to keep pace with both the volume of transactions and the evolving nature of threats.

 

Experts broadly acknowledge that the additional authentication step may introduce some friction for users accustomed to the speed of current payment flows. However, the consensus view is that the trade-off is worthwhile — a modest increase in transaction time in exchange for a substantially more robust defence against fraud and unauthorised access. For millions of Indians who have made digital payments a part of daily life, these changes are ultimately designed to make that habit a safer one.
