Funniest shit is when you finally sometimes fall victim to the feeling of "Ok fine, I'll use Twitter for the auth so I don't have to fill out the fucking 10 field form just to be able to sign up, why you need to know my current position anyways?" and when you're finished, they're just using the auth to autofill the username and email for the signup form and you have to fill it out regardless.
Because most teams didn't write their user-auth code, it's either a framework or another team. But the PO want "Sign in with Twitter" so you hack this together.
