I too, am in the camp that would like to see open alternatives to the proprietary SSO function.  To me this is much more than just a technology problem, however.  It&#x27;s a two sided market creation problem.<p>Email providers don&#x27;t have significant incentive to become Identity Providers; Web site owners do not have significant incentive to accept persona at least until many users adopt&#x2F;request it; Users are mostly unaware of Persona&#x27;s existence and the argument in favor for many is rather weak as the people who seem to care about privacy seem to be in an exclusive club.<p>There are a few keys to success that I can think of off the top of my head:<p>1. Solid awareness campaign to explain benefits to non-HN type users.  Would depend on solid benefits of security, convenience&#x2F;simplicity, and privacy.<p>2. Fantastic &quot;default&quot; identity provider as most email providers will not, in the short term, become Identity Providers.  This has to work without sacrificing UX, security, convenience&#x2F;simplicity, and privacy.<p>3. Adoption by at least 1 major email provider (e.g. FastMail).<p>While I don&#x27;t bring much in the way of development skills (not my strength at all), I would be very willing to help on the strategy, partnerships &#x2F; business development, marketing etc. front.
