If you are new to LON-CAPA or having problems logging in, please see the LON-CAPA Instructions.

Log In Instructions



In order to log in the first time, please point your browser to the LON-CAPA index page to find out which server you log into. Then, use the "Forgot password?" dialog, entering the proper information into the blank fields: Your NDSU e-mail id (without the portion) and your NDSU e-mail address (with the portion); do not use  The log-in name and e-mail address are case sensitive, and must be lower case.

The "Forgot Password" e-mail 'expires' after two hours. An expired link will not allow you to reset your password!

If you have any trouble logging on to LON-CAPA, contact the Physics System Administrator. Please include your Student ID and lecture/lab information if you feel you need to be added to the respective sections.
