I use a kind of "algorithm" to convert data only I know into passwords.
Sounds very abstract.
Example: Take your five favorite flowers, choose x unchangeable attributes of
this flower and arrange everything like:
Nameoftheflower_attribut1_attribut2_attribut3
You have to remember this order.
With this you look up the values of the attributes and generate the
passwords.
I know, flowers are a bad example.
You need something with many alternatives, for instance musicians.
If someone cracks one of your passwords, it's unlikely that he supposes a
kind of scheme in the password. If he does, it's very unlikely he will
recognize the bunch of numbers as attributes of the flowers, if you chose
them cleverly, AND finds the right flowers.
Though, it's not impossible, and that's the disadvantage of my method.
The advantage is:
Different passwords for each site and you only have to remember one.
You can find the others by trying out your favorite flowers and looking up
the proper attributes.
