Re: Question about "TLS CCA Session" versus "Web Session"

Melvin,

Of course you can use whatever "auth" method you feel suitable but that won't lead
to interoperability and then the market might as well continue using centralized
IdP schemes like Google.

That U2F is a suitable replacement for the (pretty much failed) WebID-TLS scheme
is something I wouldn't bet on.  The philosophy between U2F and WebID are quite
different.

Now if you want to look at matters through "actual user" lenses, then the total users of IE and Safari completely trump the users of Firefox and Chrome, who for all intents are purposes fall into the "programmer / developer" user profile.

They can work with <http://id.myopenlink.net/ods/__webid_demo.html <http://id.myopenlink.net/ods/webid_demo.html>> and switch certificates without restarting their browsers. As for the issues with Certificate selection presentation, that's less of a problem when the Certificate Generator UI aids the user accordingly re., CN attribute values.

Windows, Mac OS X, and iOS end-users don't have a problem because they use the default browsers provided by the OS.
