Login.gov is a single sign-on solution for United States federal government websites. It enables users to log in to services from many government agencies using the same username and password. Login.gov was jointly developed by 18F and the United States Digital Service. The initiative was announced in a blog post in May 2016, and the new system was launched in April 2017 as a replacement for Connect.Gov.
History The idea for the site started at the direction of the Obama administration in May 2016, when an executive memo was sent out to executive agencies. The memo was to encourage agencies to use the same tools and technology for administrative services. By sharing these tools, there would be consistency in best practices and personal information security across the executive branch.
The service is authorized by law in 6 USC 1523: Federal cybersecurity requirements part (b) (1) (D):
"implement a single sign-on trusted identity platform for individuals accessing each public website of the agency that requires user authentication, as developed by the Administrator of General Services in collaboration with the Secretary."
