Description
GUA ā Graphical User Authentication
Secure. Visual. Modern.
GUA (Graphical User Authentication) is a powerful and innovative authentication app that redefines the way users log in to systems and applications. Moving away from traditional text-based passwords, GUA uses a sequence of images selected by the user as their authentication key. This visual method leverages the natural strength of human visual memory, making authentication more intuitive, user-friendly, and secure.
š Why CAVE?
Text-based passwords have long been the default method for user authentication, but they come with well-known vulnerabilities: weak password choices, reuse across sites, brute force attacks, phishing, and shoulder surfing. GUA solves these issues by replacing passwords with a graphical login system. Rather than typing characters, users authenticate by choosing a specific sequence of images from a matrix/grid ā a process that is both secure and easier to remember.
š§ How It Works
Registration:
The user is shown a grid of images (e.g., 5x5 matrix).
They select a sequence of images as their password (e.g., 5 images).
The app securely stores this image pattern as the user's authentication key.
Login:
During login, the user is shown a randomized image grid.
They must select the images in the exact order they chose during registration.
If the sequence matches, access is granted.
