Graphical password
A graphical password is a form of authentication using images rather than letters, digits, or special characters. The type of images used and the ways in which users interact with them vary between implementations.
Types
Facial recognition
One system requires users to select a series of faces as a password, utilizing the human brain's ability to recall faces easily.[1]
Image sequence
In some implementations the user is required to pick from a series of images in the correct sequence in order to gain access.[2]
Image-generated text
Another graphical password solution creates a one-time password using a randomly generated grid of images. Each time the user is required to authenticate, they look for the images that fit their pre-chosen categories and enter the randomly generated alphanumeric character that appears in the image to form the one-time password.[3][4]
