STANFORD ONLINE IS RETIRING THE LAGUNITA ONLINE LEARNING PLATFORM.
All open courses end at 12 noon Pacific Time on March 26, 2020. See Lagunita Platform FAQs.
Some former Lagunita courses are now open for enrollment on edX: Stanford Online launches courses on edX.
Additional courses offered on other online learning platforms are available at https://online.stanford.edu/courses.
Once your Lagunita account has been created, you cannot change your username. In addition, no other person can have the same username since all usernames are unique.
Your unique username displays on your dashboard, in exported grade reports that the instructor runs, and in the discussion forums such as the example below.
If you need to change your username for any reason, you can contact the platform support team by clicking on the Help link that displays on the top right side of Lagunita pages. The Help link takes you to the Help Center which is where you can submit a request to us. You can also submit a request by going to https://stanfordonline.zendesk.com/hc/en-us/requests/new.
