To be clear, signing-in doesn’t trigger a transaction. So people can’t publicly see where you have logged in.

Also it’s up to you how you use the system. You could have a number of online persona’s each with it’s own login.

This isn't about transactions or being able to see where you're logged in from.

This is about having a public, centralized source of identities that cannot be erased.

Yes, you can have multiple identities on it - but if an identity on that chain is doxed, it is forever doxed.

If you are maintaining one identity per application... then what is the advantage of having the identity in a place where it can be accessed by multiple applications?

I have difficulty seeing the advantage of a public, append only, identity provider compared to say... setting up your own auth server on AWS and managing your identities out of there.
