graphical user authentication An alternative to the alphanumeric password for security. When prompted, users select a sequence of images from a page full of images; for example, a tree, glass of milk and red fire truck. The image sequence is easier to remember than a meaningful alphanumeric password, which should really be a mix of digits and letters and not obvious such as name or date of birth. What keeps intruders from guessing the correct image sequence is the large number of possible image permutations. Delays are also added after a wrong sequence is chosen.Want to thank TFD for its existence?
