WoozyMasta / steamcmd-2fa

A tool for SteamCMD that automatically generates and uses a Steam Guard code upon login, or simply used as a code generator.

steamcmd-2fa

A simple tool that automatically generates a 2FA Steam Guard code and then runs steamcmd with that login and the rest of your arguments.

Important

Please keep your seed/secret VERY safe as people with your seed can easily bypass your 2FA by simply generating the Steam Guard codes themselves!

Installation

Install a pre-built application, direct download or use curl:

curl -#SfLo /usr/bin/steamcmd-2fa \
  https://github.com/WoozyMasta/steamcmd-2fa/releases/latest/download/steamcmd-2fa
chmod +x /usr/bin/steamcmd-2fa

You can either clone this and build it yourself or use the supplied binaries for both Linux and Windows.

git clone https://github.com/WoozyMasta/steamcmd-2fa
cd steamcmd-2fa
cargo build

Usage

Usage: steamcmd-2fa.exe [OPTIONS] --username <USERNAME> --password <PASSWORD> --secret <SECRET>

Options:
  -u, --username <USERNAME>        Username to login [env: USERNAME=user]
  -p, --password <PASSWORD>        Password to login [env: PASSWORD]
  -s, --secret <SECRET>            2FA shared_secret (base64 encoded) [env: SECRET]
  -c, --code-only                  Generates only TOTP code for authentication
  -a, --args <ARGS>                Arguments to pass to steamcmd [default: "+@ShutdownOnFailedCommand 1 +quit"]
  -b, --before-args <BEFORE_ARGS>  First positional args like +force_install_dir
  -d, --path <PATH>                Path to steamcmd binary, [env: STEAMCMD_BIN_PATH=]
                                   default one of:
                                    - /home/steam/steamcmd/steamcmd.sh
                                    - /usr/bin/steamcmd
                                    - /home/steam/steamcmd
                                   or
                                    - C:\steamcmd\steamcmd.exe
  -h, --help                       Print help
  -V, --version                    Print version

For example, instead of running steamcmd +login USER +quit, you would run:

steamcmd-2fa --path /some/path/steamcmd --username USER --password PASSWORD --secret SECRET --args +quit
steamcmd-2fa -u USER -p PASSWORD -s SECRET -b +force_install_dir -a '+app_update 223350 +quit'
USER=user PASSWORD=pass SECRET=secret steamcmd-2fa

To simply retrieve a token:

steamcmd-2fa -s SECRET -c
SECRET=secret steamcmd-2fa -c

You can get your 2FA seed by various methods. Your seed here is the shared_secret.
