Maybank has announced that it will no longer use the SMS-based MSOS (Maybank Secure Online Shopping) code system for approving online transactions starting 6 March 2025. This change applies to both credit and debit card transactions, requiring users to authorise payments through the Secure2u verification feature on the MAE app.
The bank states that this move is part of its ongoing efforts to enhance the security of online transactions. Customers who have not yet activated Secure2u are encouraged to do so to avoid disruptions in their future transactions.

Secure2u links your device to your Maybank2u account, ensuring that transactions can only be authorised on your registered device, reducing the risk of TAC fraud. It includes a 12-hour activation period for added security and allows users to generate a Secure TAC or approve transactions via Secure Verification, eliminating the need for SMS-based codes.
To enable Secure2u, users must download the MAE app from the Apple App Store, Google Play Store, or Huawei AppGallery. Activation requires completing the registration process within the app and verifying it at a Maybank ATM.
