PassWindow assumes hackers already have electronic access to your computer or mobile.
With only the challenge image being passed from the internet there is no hardware or software for the hackers to tamper with.
The inherent simplicity prevents the normal hi-tech attacks employed against complex security systems.
Each frame displays a single digit which the user enters consecutively.
Your browser can store the exact position of the screen challenge relative to your card for future authentications. This requires little to no manual alignment on behalf of the user.
First time pattern alignment is achieved simply by dragging the challenge pattern behind the card pattern with the mouse. Once alignment is achieved the coordinates are stored in the users browser or online database for future use.
The dynamic password method generates a new authentication password every time, easily enabling multiple password requirements for strong authentication.
