Welcome to the European Commission Authentication Service (ECAS).
Choose the institution or body for which you want to log in. Choose "External" if you don't work for a European institution or body. Choose "W+7" if you have a special external account composed of w and 7 digits.
If you aren't sure, select the "I don't know?" option for help.
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.
