To protect your account, the UCLA Single Sign-On Service prevents old or previously used login pages from use. You may have clicked browser's back button or waited too long at the Logon page before signing in. Further, this service uses cookies and javascript in your web browser.

Please make sure that cookies and JavaScript are enabled and restart your login attempt. Enter the application's web address directly in your browser. A bookmarked UCLA Logon page won't work.

For further assistance please contact the IT Support Center at [email protected], copying the information below and filling in missing items if necessary:
