Do we need a dedicated route for setting up fingerprint? Can a user even
navigate directly to fingerprint, ie, because to change fingerprint we need to
also capture the password?

[sammiequon, 2017/05/04 23:32:34]

Yeah it's still possible for a user to navigate directly to fingerprint :-(,
haven't got around to that yet.  We can remove this dom-if once that gets
prevented.

[jdufault, 2017/05/04 23:39:03]

Can we just remove the route entirely? Do we have a reason why the user needs to
be able to navigate directly to fingerprint?
