Okay I have a question.

Up till now, my browser-based products use Twitter for identity.

You can tell you're logged in because in the upper right corner of the screen there's the Twitter signature next to your screen name, the little blue bird.

Now if I were to use Mastodon for login, what would I use in place of the blue signature.

Another problem, mastodon addresses are much longer than twitter screen names. I'm going to have to shorten them

See the screen shot below for context.

@davew This is something you can do? Mastodon supports OAuth or something?
