What is Persona?
Persona is a new way to sign into websites. With Persona, you can:
- sign into websites using your email address and a password
- use a single password to sign into any website that supports Persona
- use multiple email addresses, and choose which address you want to use with each website
Persona has been designed from the ground up to protect your privacy and put you in control of how your data is shared. It works on all major desktop, smartphone, and tablet browsers.
Sign in with your email address
With Persona your username is your email address.
You can use any email address, as long as it's one you own - you have to prove you own it. You can use more than one email address: so you could use your work email address to sign into work-related accounts and your personal address to sign into personal accounts.
No new passwords
Most of us have several websites we sign into, and many of us have dozens of them. It's very difficult to remember a separate strong password for each site. Using the same password for every site is easier, but it means that if one site is hacked, the attacker could get access to all your other accounts.
Persona is different:
- If your email provider supports Persona, you can sign into any Persona-enabled website without needing any new passwords at all.
- If your email provider doesn't support Persona, you'll need one new password for all sites.
Either way, you never send a password to the websites you're signing into. You sign into your email provider or the Persona service instead, and then you can sign into websites without giving them a password.
With Persona you get the best of both worlds: a single password for all websites, but because the websites never see your password, it can't be stolen if a site you sign into gets hacked.
Persona takes privacy seriously
Many of our interactions on the web involve sharing and exchanging personal data. As we do so, we enable the companies that provide web services to collect, correlate, and sell information about us in ways we can't control.
Mozilla wants to give the user control over the data they share, and an identity system - Persona - is the first building block. There are other identity systems, such as Facebook Connect, in which you can sign into multiple sites with a single password, but they rarely respect your privacy. With those systems, the website has to "phone home" to the provider - Facebook, for example - which is then able to compile information about your browsing habits for its own purposes.
We've designed Persona from the start so that's not necessary. At the moment, Mozilla's Persona service does get to see which websites you sign into, but we're working on removing this requirement, and in future versions of Persona nobody will be able to track which websites you visit.
Not just Firefox
Persona works where you do, it's not just for Firefox users. You can use Persona on the desktop with Internet Explorer, Firefox, Chrome, Safari, and Opera; on iPhones and iPads with the Mobile Safari; and on Android phones and tablets with Firefox and Chrome.
