Anytime the ENS sign in stuff is brought up, I feel obligated to point out the following: Alex Van de Sande, the co-founder of ENS, posted in 2018 an interesting demo with UniLogin, "[Universal Logins demo for Ethereum](https://www.youtube.com/watch?v=F5t94cCg6XE https://www.youtube.com/watch?v=F5t94cCg6XE)". [The project was abandoned in 2020](https://medium.com/universal-ethereum/out-of-gas-were-shutting-down-unilogin-3b544838df1a https://medium.com/universal-ethereum/out-of-gas-were-shutti...). This is a hard problem that needs a fantastic solution. I don't think sign in with Ethereum is better than UniLogin. UniLogin was good, the team was smart, and this was still too much of a problem for them to feel like it was worth their time to solve. Then there's the significant problem of state expiry. How do you log out? I don't see that they're really addressing this problem. Right now the EIP has the attitude to "push that problem down to the servers". Websites need complete solutions, not more problems. Others have already made progress down this road, and I don't see anything different from what has already been done before.
