Since you said "even discussing", might as well mention that the Rust community has discussed adding 2FA support to cargo: https://internals.rust-lang.org/t/requiring-2fa-to-publish-to-crates-io/7931 https://internals.rust-lang.org/t/requiring-2fa-to-publish-t.... But as far as I know, crates.io/cargo still has no 2FA feature of its own. On the other hand, if your crates.io account is linked to a GitHub account, you could have 2FA via GitHub. So I'm not entirely sure whether "cargo supports 2FA" would count as true or false at the moment.
