The strings command is pretty old can do it if you're naive enough to embed a username and password into the game client.
The main thing is that its privileged - having a token shouldn't let you do anything besides say, report your game stats to a central server or enumerate the server lists, things like that.
TBF strings might not trivially show up the password if you took the most basic of provisions (a non-ascii password, not stored right next to the username separated by a \0), but most programmers likely wouldn't even bother with that.
