Passfaces is a unique alternative to passwords or biometric authentication that functions on the human brains ability to remember familiar faces. The system, currently only available as a demonstration, assigns the user a unique sequence of 5 faces. When the user wishes to login they are asked to recall the faces from 5 sequential 3x3 grids of faces, this is surprisingly intuitive and is easy for the user whilst almost impossible to be guessed, copied or stolen. Try it out.
