For people who can't write their own programs, or don't want to, there's an easier method to solving the multiple password problem: use a salt. That way you can have a single password for every site/app/etc. but each one is different. All you need to do is note the salt key for each password, and this can be in plaintext because few people will understand what it means (unless you label the file "salts for my password" of course...)
