As a counter to this I'll bring up that the Swedish Bank-ID works on all of my devices, all of which are Google-free and have root access, most of which run LineageOS. The Bank-ID client throws up a warning that it "needs Google services to work" after which it continues to work fine without it. I do tend to use older devices - waste not, want not - so things may have changed somewhere past Android 11.

I have a hard time believing this. I'll have to look into it, because I do have a spare pixel 6 device I'd like to install Lineage on, but I also want to use it as backup for my BankID.

I use Bank-ID on a 2014 Samsung Galaxy IIIneo running LineageOS as well as on a Galaxy Tab 3, also running LineageOS. I also use it on a Xiaomi Redmi Note 5 running a lobotomised stock distribution. None of these devices have Google services installed, all have root access using Magisk. These devices range from Android 7 (the tablet) to 11 (the Galaxy SIIIneo), i have no data on more recent Android versions.

Pixel 6 supports grapheneOS which is massively superior in all ways, at least in my opinion as someone who has used both lineageOS and grapheneOS for many years
