Not a criticism, but something to consider for other folks. Not everyone is able or willing to de-Google/Apple and seek alternatives.
In Singapore, the regulators have directed banking apps to “secure” the mobile banking environment. This includes library tampering detection and irregular activity detection. These banking apps also only exist in the Google Play and App Store walled gardens, while the regulators also gave them the key to a duopoly control over the local smartphone market. All in the name of preventing scams and frauds. Their intention meant well, but at the cost of consumer rights. Bear in mind digital payments and physical tokens replaced by the apps are the norm here.
De-Googling and carrying another phone just for everyday mobile banking is going to be quite a chore.
For better or worse, no.
The mandatory 2FA used to be either physical tokens (a small dedicated device that generates the codes, not too different from the 2FA apps), or sent through SMS.
The physical tokens are phased out, while SMS was demonstrably insecure due to interception.
So everyone is stuck with 2FA through the mobile banking apps, for logging in to the web browser banking platforms.
