Stop worrying about storing passwords.

Mozilla Persona lets users sign in to your site in as few as two clicks, so you can say goodbye to the headaches of storing passwords.

Forget passwords

Securing your users’ passwords takes resources away from your primary focus: maintaining and developing your application. But no matter how well you do it, you can still get hurt when people use the same passwords on other, less secure, sites. Although this is a risk you can’t control, your reputation still suffers when password compromise happens.

Breezy to implement

Adding Persona to your site can take as little as 15 minutes. Include our JavaScript shim on your website, make two JS calls and one CURL on the server to verify, and you’re in business. Detailed instructions are, of course, maintained on the Mozilla Developer Network.

Low commitment

Persona’s not a silo from which there is no escape. Users always provide a verified email address which makes it easy to transition to or away from Persona.

Today a service, tomorrow a standard

Currently Mozilla supports Persona by providing the supporting infrastructure, but soon it will be available natively in products like Firefox and other browser add-ons. We are working towards making it a standard that can operate independently of Mozilla services, leveraging existing standards like HTTP, JSON and JWT. Until that time, Persona is just a JavaScript call away.

Mozilla to the rescue

Mozilla’s mission is to promote openness, innovation & opportunity on the Web. And just like our flagship product Firefox, Persona champions you – your security, privacy, and the quality of your online life.

Improved privacy

Persona is developed by Mozilla, a not-for-profit company trusted throughout the Web community. Our goal is to create technologies that balance an open Web platform with people's privacy.

Password-free for 700 million

Persona allows users to sign into sites with any email address, but is especially convenient for Gmail & Yahoo addresses where no new password need be created.
