Probably not the case for most people. I'm living abroad and had to do something on the Brazilian e-gov platform. To log in I had to confirm my ID with an Android app. Not only is it exclusively on Play store, but it also refuses to install on any rooted device, so I had to boot an old non-rooted Android I had stored somewhere.
I'm confident this is a very common experience worldwide, be it with gov IDs or banks.
Basically yes. Maybe you can access the "unprotected" version, which is basically useless as all the features necessitate an android/iphone device for 2fa.
