I don't get the point of password managers. What's so hard to remember a password? Just use the first name of your eldest child, add your house number, and you're golden. If you're really that dumb, post-it notes exist for a reason.
I've made their passwords incredibly easy to remember. They're just not able to for whatever reason. They're both practicing doctors who I generally believe to be competent but for whatever reason passwords elude them. Maybe crypto just won't work until all the people who grew up pre-internet die.
