> I've been surprised to learn that several of my non-technical friends forget their passwords and rely on cookies

As a "technical" person, I despise passwords and tend to avoid using them. My preferred way to log-in somewhere is either with ssh keys or with single-usage codes sent by mail.

This has nothing to do with "losing" passwords. For example, I actually have a password for amazon written in a file, but I don't bother looking for it, I prefer to use the single-usage code anytime I want to use the site.
