What is ECAS?

ECAS is the European Commission Authentication Service. It allows users to access a wide range of Commission information systems, using a single username and password. Once you log in, ECAS will remember you as long as you keep your browser open. During that time, you won't have to identify yourself again, no matter how many online services of the Commission you access.
