Authorization relies on information your browser stores on your computer, called "cookies." If the cookies are deleted, so too is the authorization.
School network environments where children log in to their own profiles, or where the cookies are purged regularly require an alternate authorization mechanism to stay authorized. This mechanism is an HTML file or a URL that can be placed on the school's shared network or individual computers, and bookmarked within the browser. Clicking on the file or the URL authorizes computers at your location.
School Members in the United States or Canada can request an alternate authorization method. Enlist your IT professional or network engineer to complete the Alternate Authorization Request Form.
