SSI (Single Sign-In) is the security gateway to supported applications. It provides user account maintenance, application access control and user authentication. If you have questions about existing user accounts, possible training or have difficulty using SSI for login then please feel free to contact the Helpdesk at 1-866-577-0771 or e-mail the Team at app_support@acf.hhs.gov. Applications are supported on an individual basis depending on the support agreement with the application owner and by the program office on a program by program basis. It is always best, if you have questions on the applications to contact your program office (or regional office) first for assistance. They will either refer your issue to the proper place or ask you to contact the support office involved. The Helpdesk covers support for about 50% of our users for the applications and programs, by agreement. If you have any suggestions as to how you would improve your experience with SSI or the applications it supports, please feel free to contact the Helpdesk or the support office involved. We would love to hear from you.
