Note that Mozilla Persona did not support passwordless authentication. Specifically, you would still need to create a Persona password if you didn’t use a Gmail/Yahoo email address.

I’ve tested this service with one of those 10-minute emails and it seems to work without any passwords, so true passwordless authentication.

Yep! Requiring a separate account for Persona was, in hindsight, misguided. I've written a bit about what Persona got right and wrong, and how we* plan for Portier to be different, at https://github.com/portier/portier.github.io/blob/master/Oth...

*Though Mozilla supported my work on this, Portier is an independent side project with significant code contributions from folks outside Mozilla.
