Hi there, I'm Markos Charatzas, the author of the post. This is actually a series of posts written (http://qnoid.com/2012/11/10/A-post-about-user-identity-that-is-thought-provoking-on-user-authorisation-and-security%2C-or-just-utter-bullshit..html http://qnoid.com/2012/11/10/A-post-about-user-identity-that-..., http://qnoid.com/2012/11/10/Mockups-on-user-identity.html http://qnoid.com/2012/11/10/Mockups-on-user-identity.html, http://www.youtube.com/watch?v=_9Zu-AHhXyo http://www.youtube.com/watch?v=_9Zu-AHhXyo), talks given (https://speakerdeck.com/qnoid/user-identity-nsconference-2013 https://speakerdeck.com/qnoid/user-identity-nsconference-201... https://speakerdeck.com/qnoid/user-identity https://speakerdeck.com/qnoid/user-identity) and open source code released (https://github.com/verylargebox/VLBUserIdentity https://github.com/verylargebox/VLBUserIdentity) on how we should think of user authentication based on existing user behaviour (never signing out) and trends (long lived sessions, email verification).
