New features include ‘Identity Bridging’, which essentially means that users can now log into Persona-supporting websites with their existing Web and email accounts. Mozilla hopes this will make it far more attractive for application developers, service providers and online publishers to implement Persona as (part of) their authentication flow – they need this to have even a small chance of broad uptake.
It’s worth noting that any domain holder can now become a Persona Identity Provider so users can reuse their existing accounts on any site that uses Persona. You can find a bunch of early adopters in Mozilla’s blog post.
Finally, Mozilla says Persona has become ‘twice as fast’ as before, with quicker pop-up windows and other performance improvements.
Mozilla says its goal with Persona is simple: to eliminate passwords on the Web with a free, open alternative login system that allows users with existing Web accounts to log into services without the need to create a new account or password.
