Question: 

How can I define or change my password?

Answer: 

Please go to the authentification page, click on link "Need Help?", and select "I've lost my password". You will be requested to enter your login. If the login is found, you will shortly after receive an automated email containing a link to redefine the password. This link is only valid for 48 hours. In case the delay is past, you can do the same procedure again. In case the login was not recognised by the system, please refer to the other option "I've lost my login" to retrieve your login.
