CS:GO - Can't login to Steam Console Client

[typhoon455]

Hello,

I'm trying to set up a CS:GO server on my Linux dedicated server. I've downloaded the new SteamCMD client and followed the instructions on the developer wiki, but I can't seem to log in to the Steam client to start the download for the CS:GO server files.

Here's what the ouput looks like:

Steam>login myusername

Logging in user 'myusername' to Steam Public...
password: **********
Login Failure: Account Logon Denied
Failed.

Any ideas?
