raccoondad Banking may become an issue, but you can still login through the website
In the EU and UK this is increasingly becoming impossible. Specific types of 2FA are legally mandated (look up PSD2) for logging in and making transactions. Some banks still offer SMS-TANs or physical TAN generators, but many others require an Android/iOS app. I have (or had recently) accounts with 10 banks and my experience was:
- 2 give you a choice of SMS, physical card reader, and app
- 5 give you a choice of physical card reader and app
- 3 require the app with no opt-out
Note that the majority of the banks require you to pay for the physical TAN generator.
So if you're unlucky you have to either change your bank or revert back to stock Android or get a second phone just for banking.
