Zombie Cookie Registration Error with Universal Browser Credential (UBC)

    Applies to:
  • Legacy SecureAuth IdP
Deployment model:
  • On Premises
  • Affected SecureAuth IdP Versions: All versions


    When a user is logging onto a realm using Private Mode with Universal Browser Credential enabled, the user receives the following error:


    The zombie cookie that is injected to the browser during the login process becomes stale and cannot be removed due to the sticky nature of the zombie cookies.


    The use of Universal Browser Credential (UBC) has been deprecated after SecureAuth IdP v9.0. It is still available as an option, but it is no longer recommended. For a short term fix, the user can still log in using Public Mode. We recommend switching Browser/Device Fingerprinting for a long term solution.


    To learn more about how to set up Browser/Device Fingerprinting, please refer to the doc located here.
