* `STEAM_PASSWORD`: The password for the account

* `STEAM_SHARED_SECRET`: Optional, a SteamGuard shared secret ([setup steps](#shared-secret))

* `STEAM_CONFIG`: Optional, a steam account config.vdf encoded as base64 string ([setup steps](#config))

* `STEAM_SSFN`: Optional, a steam ssfn file encoded as base64 string. Optional, with `STEAM_CONFIG` setup.

* `STEAM_SSFN_NAME`: Optional, the name of the `STEAM_SSFN` file that was encoded. Required with `STEAM_SSFN`.



### workflow



```yaml

steps:

    # sets up the steamcmd command alias

    id: upload

    with:

      username: ${{ secrets.STEAM_USERNAME }}

      config: ${{ secrets.STEAM_CONFIG }}

      description: 'Your build description here'

      content_root: '${{ github.workspace }}/Build'

      set_live: 'beta'

      depot_file_exclusions: |

        bin/tools*

        *.meta

      install_scripts: 'localization/german/german_installscript.vdf'

    # use outputs

  - run: |

      manifest="${{ steps.upload.outputs.manifest }}"

      cat $manifest

## Multi-Factor Authentication Setup



Deploying to Steam requires using Multi-Factor Authentication (MFA).

This action requires at least one of these authentication methods are set:



* `totp`: A temporary one time pass code (totp) from SteamGuard Authenticator app.

* `config`: Steam [config.vdf](#config) encoded as base64 string.

* `shared_secret`: The [shared secret](#shared-secret) from SteamGuard's two-factor authentication.



### Temporary One Time Pass Code



Can be obtained from SteamGuard Authenticator app. Usually is temporary and resets after a set amount of time.



### Config



To setup steamcmd for continuous integration, or just on a machine or VM that will get re-imaged frequently, you'll need to include the config file that contains your login token. Follow these steps so that your initial login token is properly saved:



* Download [steamworks sdk](https://partner.steamgames.com/doc/gettingstarted)

* Unzip steamworks in your desired location

* Open in explorer or finder

* Navigate to `sdk/tools/ContentBuilder/builder` (or osx/linux if on non-windows)

* Copy the path to the steamcmd executable (`steamcmd.exe` for windows, `steamcmd.sh` for osx/linux)

* In a new terminal run `/steamcmd.exe +login `

  * If prompted, enter your password and the SteamGuard totp

* Type `info`, and you should see your account listed as connected

* Type `quit`

* The folder where you ran `steamcmd` should now contain new content with config directory.

  * `/config/config.vdf`

  * If you're unable to locate this file, it can also be located in your steam installation directory

    * windows: `C:/Program Files(x86)/Steam/config/config.vdf`

    * linux: `~/home//Steam/config/config.vdf`

    * osx: `~/Library/Application\ Support/Steam/config/config.vdf`

* Encode the file to base64 string

  * In a new `bash` terminal run `base64 /config/config.vdf > encoded_config.txt`

* Copy the contents of the encoded text file and paste it in `STEAM_CONFIG` secret in github actions.



> [!NOTE]

> If you change your account's security settings or get a new code sent to your email, you'll need to follow these steps again.



### Shared Secret



> [!WARNING]

> Obtaining a shared secret from the SteamGuard Authenticator app is challenging and complicated.

> It is recommended to use the [config](#config) setup.

> This shared secret should not be checked into source control or shared with anyone!



> [!IMPORTANT]

> If you've already got SteamGuard setup for your account and you remove it, you'll have to wait 3 days before being able to publish a live build.
