When I want to enter multiplayer it asks me to put the password and the user. The detail is that I forgot the password. What I can do?

You are now online on a server, so does it work now?
At https://www.lfs.net/account/details you can enter a new GAME password (for playing) or a new WEB password. (for forum/website)
