    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:
