A universal system would require us to create only one user ID and password for everything an individual does online, at work and at home. There are lots of online identity-verifying systems out there, and some experts see the sheer number and diversity of those systems as a big part of the Internet's fraud and security problems. Universal Authentication if implemented, it will give secure, but password-less logins for web-based services. Even better than single sign-on ideas like Passport. net or Liberty Alliance. Problems do arise when we want to login from any other terminal that doesn't have our private keys installed.
This can be solved by introducing relays. When the browser doesn't know how to authenticate to this website, it can ask the user if it knows any relay service. The relay will respond on behalf of the browser, but it will require a username or password to work. The relay can be done over HTTP or https and can use Basic or Digest authentication, with an addition header: Relay-Authenticate. If the relay finds the credentials given valid, it will respond to the challenge with the right header in Relay-Authorization.
Then the browser can forward this to the web server. Note that a relay can be a mobile device with WLAN capabilities, or a personal server reachable over the internet included in your home broadband-router for instance, a service provided by your boss, or any public server that you trust with your private key. The point is, your personal data is not on Microsofts Passport service or any other companies server that you might not like, and no-one has a single point of control.
Advantages of Universal Authentication 1. You don't give passwords to servers anymore, meaning no more passwords to remember. 2. Single sign-on without a single point of control like Password. 3. The authentication is potentially stronger than can be reached with six to eight char passwords. 4. You can always use a relay, which could be something you have with you always (like your mobile! ) or your home router.
