I keep getting this message when I am trying to finish my registration online: "You didn't enter your sign-in name or password correctly. If you've forgotten your credentials, please contact your site administrator for assistance so that you don't lock your account."
Thank you for reaching out in the Community!
I recommend selecting the 'Forgot Username or Password' link when attempting to log in to the Enrollment site. You can also reach out to the school to locate your username and assist resetting your password.
I would also check that you aren't being logged out of the Enrollment site due to a long period of no activity. To do this, you can refresh the site and log in again.
