Excalibur utilizes the user’s smartphone to act as a secure hardware token for any and all authentication and authorization needs. The ultimate goal is to move all forms of authentication and authorization away from passwords, replace them seamlessly with smartphone-based strong but user friendly multi-factor authentication. Excalibur's unique value is in providing backward compatibility with all the applications, Operating Systems (OS) and services used today thus creating a bridge between the password-based present and password-free future.

One of the core innovations of Excalibur is its ability to defeat all attacks on credentials as Excalibur is able to automatically change a password on each login. In the Excalibur user flow – the password is no longer entered by the user – the user never even knows the password, it is just a random string used in the background, seamlessly injected into the login process by Excalibur. The user instead just interacts with the smartphone – using it to provide various authentication factors as required by the defined security policy.
