It's kinda neat when you do, though. For the obvious reason, of course. But I find also that it has the extra feature of showing you all at once just how many accounts you really have.

For most people who use the Internet, I expect it's easily dozens, perhaps over a hundred. It is truly no wonder why people reuse passwords or rely on simple algorithmic tricks to remember passwords, there is literally no way the common person could develop a unique secure password on their own for all of these services and recall all of them. A secure password manager is truly the only reasonable solution.
