Mozilla didn&#x27;t give Persona the time it needed.<p>My criticisms of Persona are nothing to do with the fungible nature of email as identity, which I think is OK enough in principle (it&#x27;s no less identifying than anything else and changes less frequently than a phone number), but to do with:<p>1) The way Persona wants to centrally log-out from all sites, when a user&#x27;s experience is that they can sign-out from one site and remain signed-in on another.<p>2) The lack of 2FA in the default instance they shipped&#x2F;supported.<p>3) Some of the phrasing and language confuses users, especially after changing to Persona. i.e. They were still a user on my site identified by email address, but Persona would declare that they were not recognised... so I&#x27;d have to spend time telling the user to ignore that and sign-in anyway.<p>The core product though, was exactly what the web needed, and exactly what I needed for all of the sites I run.
