Is there a bank that is usable with a Google-free phone?

Hi,

Luxembourg banks use the local "LuxTrust" national scheme of
authentication / signature. One of the solutions is a physical "token"
that emits a numeric code that you enter as second factor. (Smartcards
are another solution, and I had a draft patch for OpenSC somewhere
sometime that allowed to use the authentication key, and plans to
extend it to the signature key... never finished it up; also
authentication uses the signature key!!! Duh.)

As to whether a Luxembourg bank would take a customer from your
country, which you do not say which that is, is another question
<shrug>
