Story


In this video Paul shows you how to build the ultimate door lock system, effectively turning your office or bedroom into a high-security vault! To be granted access and open the door, visitors will require not just two but THREE factors of authentication; an RFID keyfob, their unique PIN, and a one-time passcode sent to their phone via SMS. It's all built using readily-available low-cost components built around a Raspberry Pi.

I built the project because I love building things and combining software engineering with hardware that does something in the "real world". I'm interested in security and how two-factor authentication has augmented the level of security offered by systems which previously relied on password only, so I wanted to push the boundaries and see what as possible with a third requirement too.
