Sedicii authenticates people without sharing or storing passwords.
It is a new, patented authentication technology, based on a zero knowledge proof algorithm, that eliminates the need to transmit a password or store a password on a server to authenticate a user.
The only place the password is required to be stored is in the user's head, nowhere else, ever.
This means that providers of internet services no longer need to hold a database full of user credentials that can be a target for hackers. In essence, because passwords are never transmitted over the web there is no data to intercept and because no data is stored by the authenticating service, there is nothing to steal.
The service can be deployed as a single-sign-on service that allows a user to access multiple internet services without the need for any of those services to know the user's private password.
