Interesting question: how to safely keep passwords online

Here's a question that's been on my mind lately: Often, you like
to keep external passwords stored on your personal computer. As a quick
example, Eudora will remember your POP password for you so you don't
have to enter it every time. Obviously, Eudora keeps this on disk
somewhere.
The question is: is there any (relatively) safe way to do this? Obviously,
Eudora encrypt the saved password with some secret key, but this key could
probably be found by examining the code. A slight improvement would
be for Eudora to generate an encryption key on the fly based on some
external system state, but this is also susceptible to reverse-engineering.
