TL;DR: Bank Negara Malaysia’s updated RMiT policy tightens requirements around device binding, phone-number changes, cooling-off periods, and MFA resistant to interception, turning prior fraud guidance into mandatory controls for Malaysian financial institutions, according to Authsignal. The compliance question is now whether authentication architecture can bind transactions, devices, and trust state tightly enough to outpace account takeover tactics.
Editorial analysis by NHI Mgmt Group, based on content published by Authsignal: “Bank Negara Malaysia’s RMiT update just raised the bar on authentication. Here’s how to comply”.
Key questions
Q: What breaks when banks rely on SMS OTP as the only transaction authentication method?
A: Banks expose themselves to account takeover and transaction fraud because a stolen or relayed OTP proves only that a code was received, not that the session, device, or transaction is trustworthy.
Q: Why do device binding and transaction binding need to be designed together?
A: Device binding limits which device can act, but transaction binding limits what that device can approve.
Q: When should banks prioritise passkeys over SMS or push MFA?
A: Banks should prioritise passkeys when the main goal is to reduce phishing and credential replay while also improving completion rates.
Practitioner guidance
- Replace SMS OTP as the primary factor Move regulated customer journeys toward phishing-resistant MFA, including passkeys or certificate-based authentication, and reserve SMS for low-risk fallback use only where policy permits.
- Enforce one-device-per-user by default Build device registration and unbinding flows that make single-device binding the default, with explicit customer opt-in and audit logging for any multi-device exception.
- Bind approvals to the transaction details Make authentication codes specific to the confirmed beneficiary and amount so a reused approval cannot authorise a different payment or altered transfer instruction.
Bottom line: The policy raises authentication from a convenience layer to a regulated control surface for Malaysian financial institutions.

Transaction-bound authentication is now the real control boundary: RMiT is not just asking institutions to strengthen MFA, it is forcing them to prove that authentication is attached to a specific transaction, beneficiary, and amount. That matters because many fraud controls still validate the session rather than the value being moved. The practical conclusion is that transaction state, not login state, has become the security object that matters most.
A question worth separating out:
Q: How should teams govern device enrolment after a new phone or secure device is added?
A: Treat enrolment as a low-trust state until the device proves itself through time, behaviour, and step-up verification. That means temporary transaction limits, tighter monitoring of high-value activity, and explicit review of any exception that expands trust too quickly after registration.
