Common questions

What if I'm not a Yale student?

Some apps have a guest mode or only need a Gmail account. Apps that handle sensitive Yale data require Yale CAS login.

What if I'm an incoming student?

You'll get access once you have Yale CAS login. Sometimes that takes until the start of the semester, so hang tight.
