Are you a FIL user?
If you are registered on the Fondazione Italiana Linfomi website, you can log in EPICLIN simply by using your FIL account.
This identification method is possible by using the OpenID protocol, which allows you to use an existing account (in this case your FIL account) to sign in to multiple websites, without needing to create new passwords. The obvious advantage using an OpenID is that you can access multiple websites by remembering only one set of authentication credentials (username and password).
"Users may create accounts with their preferred OpenID identity providers, and then use those accounts as the basis for signing on to any website which accepts OpenID authentication." [Source: Wikipedia]
