Password Reuse Visualizer 0.13.1-signed No Restart
by Paul Sawaya
Ever been told not to reuse the same password across different websites? With this add-on, you can quickly see which passwords you're using the most and where you're using them.
About this Add-on
Start the visualization by clicking on the blue padlock in the add-on bar.
The visualization is fairly intuitive, but here's a quick summary of what this tool will tell you.
The green nodes represent distinct passwords you use. Hover over them to see a visual hash of your password, and click to view your password in clear text. The visual hashes are produced the same way as in the visual hashing add-on.
The blue nodes represent individual sites you use, and they're connected, by blue edges, to the green password nodes you use on that site.
You may also see orange box-shaped nodes that connect two password nodes. These are warnings about password similarity. Password similarity can be a wise and secure tool to use a single password across many different sites, so these warnings are not necessarily bad, or even a call to action. They connect passwords of the same "family".
