To enhance the security of digital payments, the Reserve Bank of India (RBI) Governor Shaktikanta Das at the Monetary Policy Committee (MPC) meeting on February 8, 2023, proposed to implement a principle-based framework for Additional Factor of Authentication (AFA) of digital transaction. “The SMS-based OTP mechanism has become very popular. But to enhance the security of digital payments, it is proposed to put in place a principle-based framework for authentication of such transactions,” RBI Governor Shaktikanta Das said. Over the years, the Reserve Bank has prioritised the security of digital payments, in particular the requirement of an Additional Factor of Authentication (AFA). Though RBI has not prescribed any particular AFA, the payments ecosystem has largely adopted SMS-based One Time Password (OTP). "With innovations in technology, alternative authentication mechanisms have emerged in recent years. To facilitate the use of such mechanisms for digital security, it is proposed to adopt a principle-based “Framework for authentication of digital payment transactions. Instructions in this regard will be issued separately," an RBI release said.
