• Starting April 1, 2026, all digital payments must be authenticated using at least two separate and independent verification factors.
• Authentication methods may include:
  • Passwords or passphrases
  • PIN (personal identification number)
  • Biometrics like fingerprint or facial recognition
  • Software tokens generated within banking applications
  • Hardware tokens that produce unique security codes
  • SMS-based OTP (as one layer, not the only one)

Two-Factor Authentication Methods:

• Example 1: OTP (dynamic) combined with a PIN (static)
• Example 2: Biometric verification (real-time) along with device binding
• Example 3: Token-based authentication paired with a password

• The RBI has mandated 2FA to address vulnerabilities in OTP-based authentication, including phishing scams, SIM swap fraud, malware attacks, and delays in OTP delivery.
• The added layer of protection is expected to significantly reduce fraud risks and encourage wider adoption of secure digital payments.

Accountability:

• Banks will be held accountable for failure to implement the prescribed security measures.
• Customers may receive compensation in cases where system lapses are identified.
• Banks will not be able to place the entire responsibility on users.
• Financial institutions will be required to strengthen their security infrastructure.

Cross-Border Rules:

• The RBI has mandated that similar authentication standards be extended to cross-border, card-not-present transactions by October 1, 2026.
• International payments will adhere to the same level of security as domestic transactions.
