So I guess the solution is just to begin to allow accounts to always register multiple emails? Although I guess the issue of multiple accounts is still going to exist if the users don't know the initial (private) email that they signed up with though unless there is a different unique ID that everyone will be able to remember.

I'm curious (and not trolling by asking) what a solution might be since email has been used as a unique account identifier for so long it is hard for my brain to think of another option at the moment.

Just a regular old username + password, kind of like HN allows?

I feel like email overtook usernames because it was more likely to be unique/memorable. I hate when websites ask me to remember a username (even though I'm using a password manager so I should really just calm down.)

		Usernames are no less likely to be unique and memorable than an email. You presumably chose something memorable for your email, so just enter that without the @foo.com bit. There, memorable and probably unique.
