steamguard-cli

A command line utility for setting up and using Steam Mobile Authenticator (AKA Steam 2FA). It can also be used to respond to trade and market confirmations.

The only legitimate place to download steamguard-cli binaries is through this repo's releases, or by any package manager that is linked in this document.

Disclaimer

This utility is effectively in beta. Use this software at your own risk. Make sure to back up your maFiles regularly, and make sure to actually write down your revocation code. If you lose both of these, we can't help you, your only recourse is to beg Steam support.

Quickstart

If you have no idea what the rest of this document is talking about, go read the quickstart.

Install

If you have the Rust toolchain installed:

cargo install steamguard-cli

Arch-based systems can install from the AUR:

• For steamguard-cli-git
• Non-git release is not officially provided. Please open an issue if you would like to help set that up.

Otherwise, you can download binaries from the releases.

Building From Source

cargo build --release

Usage

steamguard-cli looks for your maFiles/manifest.json in at these paths, in this order:

Linux:

• ~/.config/steamguard-cli/maFiles/
• ~/maFiles/

Windows:

• %APPDATA%\Roaming\steamguard-cli\maFiles\
• %USERPROFILE%\maFiles\

Your maFiles can be created with or imported from Steam Desktop Authenticator. You can create maFiles with steamguard-cli using the setup action (steamguard setup).

REMEMBER TO MAKE BACKUPS OF YOUR maFiles, AND TO WRITE DOWN YOUR RECOVERY CODE!

Full helptext can be displayed with:

Importing 2FA Secret Into Other Applications

It's possible to import your 2FA secret into other applications. This is useful if you want to use a password manager to generate your 2FA codes, like KeeWeb.

To make this easy, steamguard-cli can generate a QR code for your 2FA secret. You can then scan this QR code with your password manager.

steamguard qr # print QR code for the first account in your maFiles
steamguard -u <account name> qr # print QR code for a specific account

There are some applications that do not generate correct 2fa codes from the secret, so do not use them:

• Google Authenticator
• Authy
