Revocation would still be possible, I guess. At least it should be possible to build a revocation flow on top of blockchain. I am not so sure this kind of authentication will really catch on - the UX of Metamask and other wallets is just atrocious for say my father. BUT I do happen to like to connect to a site just with my ETH wallet, it is much nicer than using username/password or handing over ALL your data to Google for the OAuth convenience. It's a bit sad that the web is no longer a place for people with basic tech literacy, I'd love to use my Ledger Nano everywhere. I also was really fond of Civic for KYC and stuff, but it's gotten awfully silent.
