Most web2 apps supports a smaller number of SSO providers.
Technically "independent" SSO providers and similar existed, but non made it mainstream because there was no reason for App's to support them, but there was cost to support them.
There is even less reason IMHO for most App's to support Web3 login (more complexity).
Furthermore even if they do the web3 login would probably still list Google etc. as the web2 login still lists email.
It's questionable that more than one maybe two blockchains will be supported.
It's likely that often only a small number of wallets will be supported, it's also likely that "bigtech" companies like google will provide web3 logins if it becomes successful.
So, it might happen. But I don't see it tbh.
There is just no reason to go the extra length to support web3 login for most Apps/Companies.
EDIT: Also trust of the general public into anything containing the word "crypto" or "blockchain" is constantly undermined by an endless slew of scams, and money grabbing schemes. Which can hurt adoption of web3 login.

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.
