You don't really need a blockchain unless you need to keep data on a blockchain. To login and identify a user you can simply sign a message. I consider the address as the user "identity". Any blockchain data related to that address is mean to be public (some people register <some-name>.eth on the ENS for example)
If you don’t need a blockchain what makes this web3? I thought that was supposed to be the defining feature.
If it’s just cryptographically signing things we’ve had that ability since PGP came out.
And we had "independent" SSO schemes based on it, non of which gained widespread adoption (in the "independent" form).
The reason is the UX/UI flow, complexity for integrating them and users which already have it.
So if all people have a wallet at some point which they also can use for SSO that might get adoption.
Through for investment into crypto, instead of "daily using it" you probably don't want a hot walled on your phone.
So as long as "daily/frequent/casual crypto usage" doesn't become a supper common thing for large parts of the society (in the "western" world) it's hard for it to gain wide spread adoption I think.
