This is an interesting and creative method I devised for producing new and fresh passwords after the Heartbleed scare a few months ago.
The more complex and unrelated a password is, the more effective it is, so here is what I did.
I closed my eyes and pointed randomly on a map, wherever finger landed, I used that city.
Next, I flipped randomly through my words of Plato, whatever book it landed on, I used that as the second part.
The third thing I did was roll a 12 sided dice, and used whatever number came up.
The result is that I now have lengthy, alphanumeric passwords with zero relevance to my life.
