You can not recover a password, but you can generate a new one.
To generate a new password, please click on the button LOGIN; if the data is wrong you will see a caption: " Did you forget your name or password?"

Click on the Recover button (indicated by the red arrow in the image below):

Then enter your username or e-mail (in the fields indicated by the yellow arrows in the image below):

You will receive a note into your in-basket at the email address you have registered with. The note will state your username and will give you a link to get a new password.

If you do not receive it within a few minutes, please check the spam or junk mail folder.
