SMS? I don’t understand why Valve hates TOTP so much. And before you say: “They have an MFA app…”, yes they do, but even then they force people to use their own app with a special pattern instead of just following the normal standard used by Google, Microsoft and any other MFA apps… it’s like they do it on purpose for people to not use MFA at all.

I wasn’t able to find a list of affected games. I wish valve would be more open about this.

One of the games said to have been affected was “NanoWar: Cells VS Virus”, by developer Benoit Fresion.

You mean this wasn’t already the standard?
