Might I recommend a reasonably secure browser with an in-built password generator and manager? I use Firefox. You make up a username and it generates a safe password and saves it so you don’t have to remember it’d Just use a safe password for the browser itself that you can easily remember. I personally feel that’s a decent compromise between secure and convenient.
I love the basic instructions for someone debating security policy nuance. It’s like you don’t get that he’s way, way, way beyond “pick a password you can easily remember” despite the technical level of the discussion.
That’s still shifting responsibility to the users, which is great for all these crappy products, but we should be demanding better.
