When talking to folks about their auth needs, something that came up pretty frequently is wanting to collect additional information on signup. Often this was just name, sometimes it was a username/display name.
Since we fully manage the auth UI, I realized the simplest version of this feature is just a toggle. If you want to collect name, you toggle that option in your dashboard and all the UIs update. New users are prompted to enter their name when signing up. Old users are prompted to update their name when logging back in. The account pages let your users update their name.
The power feature here, in my opinion, is we can also manage your user's profile pictures. This lets our customers' users upload their own photos, and our customers can embed these photos in their applications.
