@mattly @stonebear I'm just talking about 2FA. It's perfectly reasonable to require 2FA on all accounts. It's safer to err on the side of requiring unimportant accounts to have 2FA, than risking an important user to have an account compromised.
That is entirely orthogonal to the funding structure. The risk and responsibility exists due to code sharing and trust structures, regardless whether people are paid for it or not.
On Star Trek they'd require you to have 2FA too.
