If you are a frequent user of ICOS data and services, you can create a user account. Using the services while being logged in through your account makes it possible to download data without accepting the data license every time you download data. The account will also keep an overview of data that you have downloaded and store the last data card. The last service makes it possible to come back to the data search from another device if needed.
You can sign in with your institutional login through eduGAIN (preferred) or, if that does not work, through the social or password login. For the password login you should first create an account. You can create an account through the same page as the account login.
