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](https://mozillians.org/), [Mozilla Moderator](https://moderator.mozilla.org/), and [Mozilla Reps](https://reps.mozilla.org/). Mozilla is making use of Auth0’s [passwordless authentication](https://auth0.com/passwordless), [LDAP](https://auth0.com/docs/identityproviders#enterprise), and [social connections](https://auth0.com/docs/identityproviders#social) features to make it easier for contributors and employees to gain access to the various services Mozilla provides. ![Mozilla Website](https://images.ctfassets.net/23aumh6u8s0i/5dfTKp8F5wIDtt7hk1spt8/851d4a34e5edbba9c22c5dce5cb99119/mozilla) We are honored to have Mozilla as both a customer and ally. Auth0 has always embraced and contributed to the open-source community and we built our platform around open standards like OAuth and [OpenID Connect](https://auth0.com/security) so that our platform can easily integrate and interoperate in any organization while still following industry standards and best practices.
