Usability of Risk-based Implicit Authentication

The research project URIA inspects the widely deployed password-based authentication. Nearly everyone knows the difficulty of choosing and, especially, remembering good passwords. Password-secured systems also inhere high security risks due to its fast “crackability”. Hence, password-based authentication has weaknesses in terms of usability as well as security. In contrast to that, Risk-based authentication has the potential of improving security without degrading usability.
