We would like to inform you that "ECAS" will be rebranded as "EU Login".

• "ECAS" disappears as a name - it will be replaced by "EU Login";
• A completely new look & feel has been developed;
• The login is done with the e-mail address - matching the users' experience on common, public web sites. Login with the ECAS username will not be allowed anymore;
