Use a GCKey

Please note that users using GCKey to login will be required to set up two-factor authentication to access Single Window starting on July 31st, 2023. For additional information on setting up and using two-factor authentication, we have added a “two-factor authentication” section to our guidance page. This will not be required by users using a sign-in partner.

For a better user experience and to improve security, we recommend the following best practices:

  • Be aware of your surroundings when you enter passwords in public
  • Avoid sharing passwords online or over the phone, even with colleagues
  • Avoid having your credentials remembered by your Web browser
  • Log off or sign out of accounts and websites when you are finished, don't just close your browser
    • sign out of your account every time you leave the computer
    • clear your browser’s cache and close your browser after your online session
