I&#x27;d disagree. My personal opinion is, BrowserID&#x2F;Persona was a bad thing for the web and it&#x27;s a good thing it haven&#x27;t hit any big. Sure, it was better than most popular protocols out there, but it was still wrong.<p>My opinion is that BrowserID had a very flawed core concept. I firmly believe that my <i>identity</i> is something that I [can] naturally <i>define</i> and <i>possess</i>. But everyone since OpenID had stolen this from the end-user and identities became something that you&#x27;re provided with - and I find the very term &quot;identity provider&quot; unnerving.<p>With identity providers you&#x27;re not you anymore, but merely your Facebook account or your email address or your domain name - a things you only temporarily <i>lease</i> from a <i>third-party</i> like an email provider or a domain registry. Sure, there&#x27;s some common sense, legal protections and stuff, but I&#x27;m don&#x27;t like merely relying on those. I think, in a sane world, at least personal (i.e. non-group) identities must be merely asserted, not provided - and they must originate from a person themself.<p>On the contrary, this login-with-ssh thingy and few other schemes (gpgAuth and WebID) are much closer to what the things should be like. While they don&#x27;t yet completely resolve the distinction between an identity and a credential (it&#x27;s really hard), they root your identity in something that you can actually define for yourself and handle without depending on anyone else - a key pair.
