Re: Cant play Steam offline?
I haven't played steam in offline mode in a long time, but IIRC you have start steam and login, then you have to go to the file->go offline option. After that you can disconnect from the net. Since you said you don't keep the account credentials on the computer there is no way for steam to authorize you.
