Check out John Park’s Circuit Playground Password Vault, a new guide in the Learning System:
Long, random passwords are the most secure, but can be difficult to remember and tricky to type. Build this portable Circuit Playground Password Vault to remember and enter them for you! Store up to ten passwords, and enter them into a computer over USB at the push of a button. You’ll even create a unique unlock sequence so your passwords stay secure, and build a rugged 3D printed case to take it on the go.
