I'm really glad they finally added this. Persona is a great way to login and better for developers and users.

What is the benefit of this (from a developer/website perspective) over using OpenID? I can't really see the difference... obviously I'm missing something fundamental...

  The main things are ubiquity, ease of use, and privacy. - Persona works with any email address. This means you can reach anyone that hits your site, without forcing them to sign up with a third party provider. - I can answer the question "what email address do you want to log in with?" I can't answer the question "what is your OpenID?" nor can I remember which of the 13 buttons on Stack Overflow I used last. - OpenID requires phoning home with every login transaction. Persona explicitly does not. Your provider doesn't get to learn where you are logging in. Edit: Put another way, can you tell me what your Google OpenID URL is without cheating? Can most people? If not, then you're only able to select a provider from a predetermined whitelist on each website. That undermines your ability to self-identify, self-assert, and choose who you trust. The open web deserves better.

    http://profiles.google.com/xistence/ http://profiles.google.com/xistence/ Or that was my Google OpenID at one point, not sure if it still acts like one or not.

      While the HN community understood that, my mother was never going to grasp the idea of ownership of a URL as a login credentials. Many people don't even understand URLs and just Google for everything they want. Email addresses have been used as login credentials for a while, so people are used to that. The explanation of Persona might be a little weird, but it's not as totally disabling to a nontechnical user as being asked to sign in with OpenID.

  In short: easier to implement, everyone has an email address, improved privacy. OpenID tells the provider every time you log in to any website, Persona does not. https://developer.mozilla.org/en-US/docs/Mozilla/Persona/Why_Persona https://developer.mozilla.org/en-US/docs/Mozilla/Persona/Why...
