This wraps up the Steam 2FA Server code in a convenient Docker container for easy deployment. This can be used as a HTTP endpoing for recieving SteamGuard 2FA codes for use in scripts.

By default this is very insecure. You should not use this for a Steam Account you care about as anyone could use this webservice. If you are using this for running a Site License Server then you can just use a new Steam Account for it and there will be no risk.

You will need to obtain the JSON token from an authenticator. The easiest way to do this is to use the Steam Desktop Authenticator. When you complete the process, there is a maFiles directory. The .maFile in here is your JSON secret. Rename it to your username.json. Do not choose to encrypt your .maFile. It needs to be unencrypted for this to work.

The container requires a volume mounted for secrets. This should be mounted to /var/secrets inside the container and it should have your username JSON files in it. This should be kept as secure as possible.

To run the container, it's quite simple:

docker run \
    --restart=unless-stopped \
    --name steamcache-authcode \
    -p 80:80 \
    -d \
    -v /data/secrets:/var/secrets \
    lancachenet/steamcache-authcode:latest

In this example, the path /data/secrets on the host will be mapped to the secrets directory in the container.

The following variables are supported to allow configuration:

• STEAM_FETCH_TIME - Defaults to true, whether to fetch the time from Valve for calculating the token
• STEAM_IP_WHITELIST - A comma separated list of IPs to allow. If left blank, this will allow all IPs.

Just make a request to http://address/index.php/code/username to fetch the code for the user. For all other usage, please check the documentation.
