CIMB Bank has announced that, from 18 April 2025, all Card-Not-Present (CNP) 3D Secure (3DS) transactions using its debit and credit cards will need to be authorised through SecureTAC on the CIMB OCTO App. This will replace the current method of using SMS One-Time Passwords (OTP).
With SecureTAC, users can approve transactions with a single tap on their mobile devices, without the need to enter a six-digit code received via SMS. This method also helps reduce the risk of unauthorised access through intercepted messages.
CIMB encourages customers to download the CIMB OCTO App from the Apple App Store, Google Play Store, or Huawei App Gallery. After installing the app, users should follow the instructions to activate SecureTAC, allowing them to begin using the new authentication process for online transactions.
For more information about SecureTAC, customers may visit CIMB’s official website or refer to the support section within the CIMB OCTO App.
