Forcing the use of the steam app for 2FA is such an ass move. Keeping this as a reminder of Valve still being a corporation with interests that can shift to the worst in a single day.

KeePassXC supports Steam's TOTP.

I sure won't call reverse engineered function and root mandatory to extract the keys from the app, "not forcing the user".

I had to install the app to try and work around a problem with Steam, and then had the same problems just browsing. You can probably disable that behavior, but I ended up just uninstalling the app entirely.

The support experience was so bad that I got really soured on Valve, and can't even get excited for these announcements now.

If I uninstall the app, I’m unable to login to Steam due to 2FA.

Opening them in a private tab circumvents that behavior (at least for me)
