While I mostly agree with you the fact that BankID does not support (desktop or non-android) linux at all or other secure auth methods like U2F for any platform is sad. If you want to be a modern citizen in sweden today you need to use at least one device with a non-free OS just to access basic services.

There is AB Svenska Pass's eID which any registered resident of Sweden can get (https://skatteverket.se/id-kort) and which supports Linux.

Unfortunately, only Swedish Tax Agency services (including minmyndighetspost.se) seem to support it, which means it's not a realistic alternative.

I think all essential services should be forced to support multiple providers.
