Is there any way to start Steam in offline mode without logging in first?

I recently find myself needing to start Steam in offline mode rather frequently (my wife is hogging my account to play Plants Vs. Zombies, and most of what I play doesn’t really need to be online).

I was wondering if there is some way to launch Steam in offline mode without first logging in (and selecting it from the menu), since that usually beats the purpose.

  • Is it possible to limit the download bandwidth used by Steam?
  • If I buy a game or DLC on one computer via Steam, can I play it on another?
  • Giving the steam Game Data to the friend
  • Workarounds for playing a game installed from a retail disk without an internet connection to download updates?
  • Where do I download the manuals for games I buy on Steam?
  • How to disable play time tracking?
  • While I know that killing my network connection before launching Steam is an option, I am looking for a more “civilized” way, such as a command line switch or something of the sort.

  • Can I have more than one of the same trading card?
  • Can I filter my Steam library by tags or features?
  • Switched Windows to Mac, do I have to buy Steam games again to play on Mac?
  • Can I create one steam account per game?
  • What network port does Steam use?
  • Enable “Play” button for Undertale on Linux Steam

    I can confirm that creating/editing steam.cfg (in the same directory as the Steam executable) with the following lines works, as long as you’ve set Steam to remember your password (thanks DarkAnime):

    BootStrapperInhibitAll=enable
    ForceOfflineMode=enable
    

    If you want to manage this with a command-line parameter, you could create a script to do something like the following (Windows .bat file):

    IF "%1"=="offline" (
        IF EXIST steam.cfgx (
            rename steam.cfgx steam.cfg
        )
    )
    ELSE (
        IF EXIST steam.cfg (
            rename steam.cfg steam.cfgx
        )
    )
    start steam.exe
    

    It used to be that you could hit “Cancel” while Steam was starting up and it would allow you to start offline mode from there, but that no longer works.

    New, working solution (2016-04-01 and it still works):

    Make sure you’ve set Steam to remember your password. Now open <Steam_installation_dir>/config/loginusers.vdf and change value of WantsOfflineMode to 1. Default location of this file:

    • Windows (32-bit): C:\Program Files\Steam\config\loginusers.vdf
    • Windows (64-bit): C:\Program Files (x86)\Steam\config\loginusers.vdf
    • Linux: ~/.steam/steam/config/loginusers.vdf
    • Mac: ~/Library/Application Support/Steam/config/loginusers.vdf

    If you don’t want warning about launching Steam in offline mode just do the same with SkipOfflineModeWarning. If you can’t see those values, just add them so it looks like this:

    "users"
    {
        "<your profile number>"
        {
            "AccountName"       "<your login>"
            "PersonaName"       "<your display name>"
            "RememberPassword"      "1"
            "Timestamp"     "<timestamp>"
            "WantsOfflineMode"      "1"
            "SkipOfflineModeWarning"        "1"
        }
    }
    

    There can be of course more users listed.

    You can change those values back to 0 to launch Steam in online mode.

    NOTE: Steam will automatically reset SkipOfflineModeWarning to 0 when it closes. To prevent this you can set the file to read-only, but then you can’t switch back easily to online mode nor make Steam remember another user. Alternatively you can use some script to change those values for you.

    To automate this on Windows machines, save

    Const ForReading = 1
    Const ForWriting = 2
    
    Set objFSO = CreateObject("Scripting.FileSystemObject")
    Set objFile = objFSO.OpenTextFile("config\loginusers.vdf", ForReading)
    
    Do Until objFile.AtEndOfStream
        strLine = objFile.ReadLine
        If InStr(strLine, "WantsOfflineMode") = 0 And InStr(strLine, "SkipOfflineModeWarning") = 0 Then
            strText = strText & strLine & vbCrLf
        End If
    Loop
    objFile.Close
    
    If WScript.Arguments.Count = 1 Then
        strText = Replace(strText, "RememberPassword", "WantsOfflineMode"" ""1"" ""SkipOfflineModeWarning"" ""1"" ""RememberPassword")
        mode = WScript.Arguments(0)
    Else
        strText = Replace(strText, "RememberPassword", "WantsOfflineMode"" ""0"" ""SkipOfflineModeWarning"" ""0"" ""RememberPassword")
        mode = "online"
    End If
    
    Set objFile = objFSO.OpenTextFile("config\loginusers.vdf", ForWriting)
    objFile.WriteLine strText 
    
    objFile.Close
    
    Set objShell = CreateObject("WScript.Shell")
    
    If (mode = "offline") Or (mode = "online") Then
        objShell.Exec("Steam.exe")
    Else
        objShell.Run("steam://rungameid/" & mode)
    End If
    

    as steam.vbs in your Steam directory and make two shortcuts to it. Add offline as parameter to one of them and it’s done. I have two Steam shortcuts on my desktop now. Steam Online with path "C:\Program Files (x86)\Steam\steam.vbs" and Steam Offline with path "C:\Program Files (x86)\Steam\steam.vbs" offline.

    I added support for games, so you can launch them in offline mode. Just start steam.vbs with app id as parameter. Example: "C:\Program Files (x86)\Steam\steam.vbs" 440 launches Team Fortress 2 in offline mode.
