I use a hardware TAN generator though I also have a banking app as a fallback on my Lineage OS phone. If I ever buy a Pixel it’s only to install Graphene OS on it.
I get most of my stuff via F-Droid or I could use Obtainium. My tablet is Google-free. This sounds like my phone should be Google-free as well.
Just use Kelvin. Problem solved.
I call them digital savages. You wouldn’t ask a jungle tribe about the Krebs cycle either.
Ah, yes. Thanks.
