Researchers at Plymouth University have developed a numerical-based security system that could replace traditional passwords and multi-factor authentication.

GOTPass, developed by the Centre for Security Communication and Network Research (CSCAN). is a one-time numerical code that doesn't depend on hardware or software to work.

It can prevent hackers from accessing confidential information, while also making it easier for users to remember and cheaper for providers to implement in comparison to developing their own multi-layered security solutions.

The solution would come in particularly useful for users who have multiple accounts with the same provider or use different devices to access their accounts.

To set up a GOTPass account, users need to create a user name and draw a pattern in a 4x4 grid, similar to using an unlock pattern on a smartphone. They must then choose one image from each of four different themes presented to them.

When they log in to a website using the GOTPass system, they will be asked to enter their unique pattern and choose two images from those presented that correlate with step two of the account setup.

When carried out successfully, they will be given an eight-digit, randomly generated code that they must enter into the login screen when directed.
