You can update your login information (username) at any time from the Edit Profile tab of your My Account section. Just enter a new username that is at least five characters long and click Update Account Information at the bottom of the page. You may be prompted to update other account information, such as your address or school/organization.

Usernames must be unique in our system, so if you receive an error message, the username entered is either not long enough or is already in use. In this case, please choose another user name.
