How to only authorize to see a user's username?

[popeeyy]

I'm planning on using the authorize feature to confirm a user's account and read their username. Is there a way to not read all their info and only their username?

I am not quite sure, what you wish to accomplish. But all Trello usernames are public so you could access usernames from the relevant profile page. Every user can chose what information they make publicly available on their profile. You can check your own public profile for example via:  http://trello.com/me

I'm trying to verify what my team member's trello is by having them login and using authorization. They seem to mess up a lot when we ask them to put their username in.
