Which sending a POST on every keystroke won't really help with anyway, because they can't tell that you typing "h-u-n" will match your old password of "hunter2", assuming it's properly hashed.

Oh, I agree. Every keystroke seems like overkill.

If I were in charge of both requirements and implementation I'd debounce the input by 300-500ms and display a "loading" spinner in the password complexity box until the debounce timer and network request had fully resolved.

I was just trying to explain why, given some business use-cases, doing password validation on the client isn't always possible.
