Login.gov

You'll need accounts for login.gov and the login.gov sandbox. These will require two-factor authentication, so have your second factor (one of: phone, authentication app, security key, CAC) on hand. To create an account at login.gov, use your regular truss.works email and follow the official instructions. To create an account in the sandbox, follow the same instructions, but in the sandbox server. Do not use your regular email address in the sandbox.
