Let's look at the current set of alternatives:
1) bop over to the browser on your mobile get out your pen, etc, write down
that pin...
2) provide a simple user/pass interface within your app, and use HTTP basic,
a scheme that gives a reasonable UX but from a security standpoint merits
jail time.

Both suck. I agree with their POV for the laptop/desktop environment, but it
is important to find a way to do better for mobile.

HTTP Digest might be a good step toward killing HTTP Basic usage.

Perhaps it is time for a better oath (or something else) that will work with
mobile? It might be more tolerable to be pitched to the browser if the pin
copy could be eliminated. Maybe the twitter server could hold some sort of
ticket state that the app could silently fetch after the user re-launches
the app.
