Probably a translation issue. I mean someone who is very participative and
active. ;)

Done. Thx

As usual, thanks for your time, patience and support.

That doens't fix the problem of restricted participation ;)

How could we (work closely with FIDO)?

Sure, U2F self-explain pictures are clear on this.

IIUC you are refereing to UAF, isnt it?. I will have a look on it.

My point is: FIDO is really cool to login without pass/U2F, but missed
(probably on purpose) the widely-used used-case of document signing.
I would love to see this included on a next version, adopted by browsers,
and we using it while ending with my painful relation with Java Applets.

Thanks a lot for your kind answers

Shall this discussion also be done at other place instead?
