I take things a step further -- I have no idea what my password is on sites like HN or reddit. If the cookie is ever gone, my account is gone.
I don't like the idea of identity permanence.
Instead of shitty passwords though, why not use something like 1Password to store the logins? I use that (or an old fashioned piece of paper in a secure location) for meaningful security tokens.
Ha. I'm in the same boat. This is my second account after the first one got ghost banned (for a single comment and the followups attempting to explain).
E.g. my hacker news account would probably be relatively unproblematic to compromise. If that were to happen, I'd just make a new one though.
