Steam-Economy-Enhancer VS SteamDesktopAuthenticator

https://github.com/Nuklon/Steam-Economy-Enhancer - does require tampermonkey/greasemonkey :)

It's on GitHub https://github.com/Nuklon/Steam-Economy-Enhancer, owned by Microsoft so there can't be any malware from any Github (forced) Open Source project. What you should fear is called r/GlobalOffensive/comments/70xofs/warning_trusted_steam_inventory_helper_now/ as it's closed source and once bad, always bad.

https://github.com/Nuklon/Steam-Economy-Enhancer This helps a lot

There are browser extensions (like this one) that let you sell all of your cards with a couple of clicks in 5 minutes.

I would recommend instead Steam Economy Enhancer: https://github.com/Nuklon/Steam-Economy-Enhancer

You need to switch to https://github.com/Jessecar96/SteamDesktopAuthenticator because if you check the WinAuth last update, it's from 2017 so it was bound to break eventually like it did on you but this project got updated last week to catch up with latest Steam update.

WARNING: This is not mine, it looks old and is general a security risk SteamDesktopAuthenticator

If you're fine with not using the Steam app, you can use Steam Desktop Authenticator to acquire the TOTP secret, then transfer the mobile authentication file to your device.
