I don't think leveraging a text-based browser is a good idea:
* No-one has one installed and they suck big time. You probably need Cygwin
on Windows to get one as well
* Would require special themes to make anything that would be remotely
* Not always usable on a remote shell. You need to do ssh (and other
things) with special commands to have an emulated terminal rather than just
a stream of characters
As separate flow and/or extending direct grant to have some sort of
challenge/response would probably be better.
Thinking about 3 different use-cases for the CLI:
* Desktop - in this case the system browser is probably the best option as
there's then SSO between web and CLIs and there's the best UI available
* Server/RSH - in this case wouldn't private/public keys be the best
option? SSH does this very well with RSA keys. We could even just use the
same keys as SSH by allowing users to upload their public SSH key
* Embedded/IoT (probably a completely different thing altogether) - in this
case the device has very limited capabilities so you probably want to
complete the authentication on a separate device
