With the popularity of mobile applications in recent years, SMS has become less and less popular. For account security, many banks are increasingly using the AppAuthorise app to authorize transactions instead of SMS TAC.
For example, Maybank has successively replaced SMS TAC with Secure2u, while Hong Leong Bank has launched AppAuthorise. Secure2u and AppAuthorise are similar features, designed to replace SMS TAC mobile text verification codes.
The benefits of using these apps to authorize transactions over traditional SMS TAC:
Benefit 1: No need to wait for SMS TAC
Have you often encountered a similar situation, when you want to transfer or trade, request a TAC or OTP verification code, but have not received the SMS TAC for a long time, resulting in you being unable to complete the transaction. If you use the in-app authorization transaction, you can authorize the transaction by clicking the push notification without waiting for the SMS verification code notification.
Benefit 2: The transaction can be completed even if the mobile phone has no signal
If your mobile telecommunications company suddenly has a problem, resulting in no signal, naturally you will not be able to receive the SMS verification code. Under the in-app authorization transaction function, there is no need to rely on telecommunications companies. You only need to connect to any internet, and you can conduct transactions quickly and easily.
Benefit 3: Safer
Verification codes provided via SMS may be vulnerable to phone number-based hacking. And it is also often seen that there are complaints from users that the bank deposits are successfully posted and stolen without receiving SMS, or that harmful applications that can steal SMS information are installed in the mobile phone.
Using in-app authorization is more secure, not only reducing the risk of fraudulent text messages but transactions can only be approved through a single registered smartphone.
It can be seen that more and more banks will replace the SMS TAC/OTP function with these in-app authorization and authentication functions.
