Bank Simpanan Nasional (BSN) will discontinue SMS one-time password (OTP) authentication in favour of multi-factor authentication via BSNSecure. The switch was announced in a now-deleted post on the bank’s Facebook page. That said, a notice on its official website revealed that the transition is slated for next month. As per this notice, the change is aimed at strengthening security, as well as protecting customers from financial fraud.
Starting from 15 December 2026, online transactions, including e-commerce transactions, will only use BSNSecure for verification. To ensure a secure and uninterrupted banking experience, customers are advised to download the BSN eWallet so they can perform e-commerce transactions using BSNSecure. As explained on an FAQ page, the platform serves as a digital wallet for BSN Cardmembers. Beyond authorising online payments, it enables users to manage their bank cards and access rewards and promotions.
