Not elegant at all, but the best option we have supported by some powerful force (Mozilla) that can push it onto users by embedding it into their browser.

Personally, I view Persona as just an awkward kludge that, while improves some important things, also does certain harm by pushing us one step away from making third parties mere notaries of one's identity, not its very providers.

Because it's me who's the source of my identity, nor my email provider nor domain registrar.
