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.

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.

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):


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
    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:

    "<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

If WScript.Arguments.Count = 1 Then
    strText = Replace(strText, "RememberPassword", "WantsOfflineMode"" ""1"" ""SkipOfflineModeWarning"" ""1"" ""RememberPassword")
    mode = WScript.Arguments(0)
    strText = Replace(strText, "RememberPassword", "WantsOfflineMode"" ""0"" ""SkipOfflineModeWarning"" ""0"" ""RememberPassword")
    mode = "online"
End If

Set objFile = objFSO.OpenTextFile("config\loginusers.vdf", ForWriting)
objFile.WriteLine strText 


Set objShell = CreateObject("WScript.Shell")

If (mode = "offline") Or (mode = "online") Then
    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.

  • As of the present time, this solution appears not to work anymore.

  • Solution works fine. Code I gave to automate it does not. I'll update it later. Commented Feb 6, 2015 at 10:53
  • Still works. Now you can launch games in offline mode too with this script. Commented Sep 2, 2015 at 23:32
  • It's worth noting that the SkipOfflineModeWarning setting is reset each time Steam runs. For a permanent solution, if you don't want to use the script each time you launch, you can set loginusers.vdf to be read-only. Commented Feb 1, 2016 at 16:06

    If you set loginusers.vdf to read-only you can't switch back to online mode easily. You have to uncheck read-only flag first, which is much more to do than simply running shortcut from desktop. I see no problem using script every time you run Steam. Also when that file is read-only you can't make Steam remember new users. Commented Feb 8, 2016 at 9:39
