For the time being, for technical reasons, OpenGovernment only supports sign-ins using the free accounts of our sibling site, OpenCongress. If you don't already have a "My OpenCongress" account, head over there
to register (it's free and only takes a minute)
and then use your OC username and password to sign-in here. Coming soon, we'll offer a full set of "My OpenGovernment" personal profiles and useful features, plus OpenID login, because we're big boosters of open standards.
(If you've forgotten your OpenCongress username or password, you can retrieve it by entering your email address.)
