Before your first login, you must create an account with Grants.gov and link it to either a Login.gov or Access Management System (AMS) account. 

Once those steps are completed, you can login to Grants.gov by clicking the Login link in the top-right corner of the website. Choose the button that matches your login option, Login.gov or AMS (for Health and Human Services grantors), and follow the prompts. 

Login.gov 

Grants.gov users are able to login with their Login.gov credentials after they have linked their Grants.gov account to Login.gov. 

If you don't already have a Login.gov account, follow the prompts on Login.gov to create an account.

AMS 

HHS grantors can login with their AMS credentials after they have linked their Grants.gov account to AMS.
