When you're asked to "choose how to sign in," you'll have the option to log in as:

  • a 1-1 (formerly NCU) student, or faculty member;
  • or as an alumni. (Alumni can find more information about login and account management here.)

If you're a class-based NU student having trouble with your password, click on the "Need help signing in?" link (highlighted in the image below) and then the "Forgot password?" link.
