Maybank has 2 mobile app
The older Maybank2u app and newer MAE. MAE has eWallet and some other features. Old Maybank2u app will be retired.
What is Secure2u?
Secure2u is the security feature to replace the 6 digits OTP (One Time Password) from SMS. It send notification through the app, and approve with the Maybank2u app or MAE app. Secure2u will be the preferred method for Maybank2u online transactions.
Almost with no choice, you will need to install a Maybank online app. Maybank still keep the SMS OTP TAC as an option, not sure when it last.

Conclusion
Things to take note:
1. The transaction approval time is short. I normally need to login the MAE (or Maybank2u) app, get ready before I preform online transaction. I experience time out issues, if do not get it ready.
2. MAE doesn't logout automatically when it was not used. You need to secure your mobile phone with your passcode. (Hope Maybank can fix this in the future)
Note: MAE seems loading and perform quite slow.
Theoritically it is more secure to use the mobile app for online transactions compare to the SMS OTP. You must secure your mobile phone and the online banking app.
