for a while facebook had the ability to recover your account by having them ask several of your friends if the recovery was legitimate but it was turned off. my guess is that not enough people added trusted contacts to bother running it.

I actually quite like this solution. Beats asking users to add a "recovery selfie" (something Meta actually does now) - I'd rather choose 3 of my friends and have them approve some notification in-app. Seems like better UX and preserves privacy a slight bit more, but we all know Meta's not in the privacy business.

		honestly I can't think of a better solution that would require a far more coordinated attack to pull off. it should work on any system where trusted folks are likely to have accounts.
