Mozilla Replaces Persona with Auth0 for Identity and Access Management (IAM)

Mozilla has chosen to replace their longstanding Persona authentication system with Auth0.

January 30, 2017

BELLEVUE, WA - As of November 30, 2016, Mozilla, one of the largest open-source organizations on the web, has replaced their longstanding Persona authentication system and has instead chosen Auth0 for all of their identity and access management (IAM) needs moving forward. The removal of Persona also means that Mozilla will no longer offer a public-facing authentication service.

Auth0 has already been integrated in many Mozilla web properties including Mozillians, Mozilla Moderator, and Mozilla Reps. Mozilla is making use of Auth0’s passwordless authentication, LDAP, and social connections features to make it easier for contributors and employees to gain access to the various services Mozilla provides.
