Visualize Your Password Reuse

There is a nice Firefox add-on that lets you visualize your password reuse.

Green dots (nodes) are passwords, blue dots connected to them are all the websites you use this particular password on. If two passwords are similar but not the same they are connected by orange edges.

My password reuse visualized

My password reuse seems quite low except for the orange spot in the middle and the small cluster in the lower left. 🙂
