If you have any ideas which utilise zk email - DM me, let's discuss! I think it's an amazing technology and in the next year we will hear about it a lot more often. Can't wait to get my hands dirty 👀

Could it transfer 2FA on-chain? Receive email w verification code 1234, and I prove this code on-chain to authorize calls. 

Launching smart contracts that require email 2FA lol

This would require proving that the email source is correct, and that the actual code is correct.

Ah true, I do find this interesting tho since other efforts of connecting social auth with blockchain requires AA while this is potentially simpler

Yes, it can be used. But I'm afraid there's a problem with 2fa, since it depends on time. Proof generation on client side can take up to 15 minutes, which makes impossible to use 2FA with less-then-a-minute interval. And generating proofs on server-side reduces overall safety.
