Frequently Asked Questions


Q: What is NIH Login?
A: NIH Login is the new name for enterprise authentication services at NIH.   NIH login incorporates  our enterprise authentication service and the NIH Federated Identity Service, which provides access to NIH applications to users at other government agencies and higher education institutions.      
Q: I often hear the term “federated identity” or “federated identity management” here at NIH.  What do these terms mean?
A: Federated identity management refers to the technology and standards used to enable the portability of identity information across organizations. NIH Login, our enterprise authentication service, is an example of federated identity management; it allows users at NIH to access web-based applications across the institution (and beyond) with a single set of credentials.  
Q: What is single sign-on (SSO)?
A: Single sign-on (SSO) is an enterprise authentication service that allows users to sign on with their user name and password a single time to access multiple web-based applications across their institution without being prompted to log in again at each application.
