I'm firmly in the pro 2FA camp, but merely as a point of discussion: the Arc codebase is already so underwater with actual features that would benefit a forum, and if I changed my password to hunter2 right now the only thing that would happen is my account would shortly be banned when spammers start to hate-bomb or crypto-scam-bomb discussion threads. Dan would be busy, I would be sad, nothing else would happen

For accounts that actually mean something (Microsoft, Azure, banking, etc), yes, the more factors the better. For a lot of other apps, the extra security is occupying precious roadmap space[1]

1: I'm intentionally side-stepping the "but AI does everything autonomously" debate for the purpose of this discussion
