I've dreamed for years about a decentralized single sign-in method. Some of the worst security issues derive from using passwords, usernames, emails, etc. Two factor authentication is ultimately just a band-aid fix for now. I truly think the killer usecase of web3 will be the ux. I'm glad that there's someone else that shares this conviction.

While signing up for Lemmy, I found myself wishing for a web3 sign-in method. Federation is great, but there are so many servers and to have an account on each would be silly. Instead of crossing the server boundary on an account from your home server, why not just have a native account on each, connected by your decentralized web3 sign-in.
