steamguard-cli

A linux utility for setting up and using Steam Mobile Authenticator (AKA Steam 2FA) on the command line. This utility is in beta.

We are in the process of rewriting steamguard-cli from scratch in Rust. Any help would be greatly appreciated! See #55 for discussion. The instructions in this document refer to the C# version.

Usage

steamguard-cli looks for your maFiles folder in the current user's home directory (eg. ~/maFiles/). Your maFiles can be created with 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!
