Click on the Sign in button in the upper righthand corner on the blue ribbon.

A screen with several log in options will appear:

NIH federal staff and contractors should use the smart card login or PIV card exemption option, as applicable. Other users should log in with one of the other options, such as Research Organization, Login.gov, HHS AMS, etc.

If none of the other sign in options apply to you, you must use the Login.gov option.
