@floriansnow @fsfe The bank I currently use (ING) supports FIDO2 in the web browser, which I had to activate in person.

The remaining hurdles are:
- the regular login page uses shadow dom and breaks bitwarden
- the password is masked, which would already make things more annoying, but combined with the previous point it's a real PITA

In Poland there's also a code-based payment system called BLIK that's shared among banks and is quite convenient, but of course the only way to get the BLIK codes would be to use the proprietary app, so I'm forced to just use my debit card for online payments.
