Using a keyboard for password or pin entry poses serious security risks with key-loggers, surveillance threats and cameras. Especially on publicly used devices like ATMs, POS, cloud computers and so on.
Keyboard use is tedious on screen-only devices. Furthermore, password memorization is troublesome.
We suggest replacing typing text passwords with selecting a short sequence of never repeating images, from layouts similar to CAPTCHA.
Where each picture in the correct order represents an answer to secret questions. In turn, each correct answer maps to part of a textual password.
We also offer an authentication solution for voice-only devices, that might not use screens at all.
These methods are much more secure and intuitive for multiple types of devices. Which makes for a smoother, safer and more efficient user experience.
