SteamDesktopAuthenticator

I have already set up 2FA in Steam for many months and I am also using the Steam Authenticator App on Android. Now I want to extract the Authenticator Key so my password manager KeePassXC can generate the Steam 2FA codes for me.

When I use the Steam Desktop Authenticator (SDA) and log in, I get the following message:

I understand that this message is normal, because I am already using an Authenticator App. And I also understand that I have to remove the current Authenticator and set up the SDA as Authenticator (what makes my current Authenticator App no longer working).

Is there really no way to let the SDA generate the same code that I have on my phone in the Steam App (my phone is not rooted)?

Reason: I often visit two friends that also play games on Steam. Sometimes I log in at their computer with my steam account to show them some games of my library. When I leave my friends, I log out and they log in using their credentials. With the Steam Authenticator App this is possible (I have it with me). But in 99% if all cases I log in at home and here I would like to add the Steam Authenticator Key from the SDA to KeePassXC.

Steam stores authenticator data in a location that only be accessed by root or the app itself; this is why it is not possible to import accounts from non-rooted devices.

Unfortunately, this does means that what you are looking for is not at the moment possible. ~~I have no experience with KeePassXC, but if they do have a mobile app, could this solve your issue?~~ (Apparently KeePassXC works differently to the password managers that I use and stores the database locally instead of a central server)

It is not possible to extract the secret keys that the Steam Android app uses without rooting your phone. Even if rooted, SDA does not currently have a way to import these keys manually into the program.

I just need the secret key so I can add it to KeePassXC. Is there any tool that can access the file without root?

I don't think so, I know some tools can see the files, but it is not possible to open them.

@OLLI-S https://github.com/steamguard-totp/steamguard-shared-secret I've gotten part-way through using this (some of it is messed up and I'm fixing it as I go). Right now I have everything I need to import stuff from the app as a maFile but it's not quite in the right format.

This looks easier for Steam's 2FA secret key extraction: WinAuth Instructions here: https://www.reddit.com/r/Bitwarden/comments/iy4jh4/use_winauth_to_get_steam_and_battlenet_secrets/

That apparently allows extracting the secret key but I didn't manage to get it working yet because it requires a phone number to be associated with Steam on top of Steam Guard being enabled.

Sure? WinAuth has been discontinued..

Discontinued yes, but it still works and is able to extract the secret so I don't see why it's a problem esp. for a 1 time use.
