Once you have authenticated your account via the Persona Identity Authority, Persona has the ability to generate new assertions for new relying parties.

Workflow would be: Go to developer.mozilla.org, click Log In, sign up for Persona, complete registration (including authentication to GMail, in my case to check for the verification email). Once I have done that, I can log into developer.mozilla.org. Later I navigate to https://5apps.com and choose Sign in with BrowserID (older branding for Persona, and still the name of the actual protocol). When I attempt to log in Persona knows that I have already registered with my GMail account, and allows me to proceed with the Authentication.

Later, I want to sign into affiliates.mozilla.org, but I use my work email address for that, so I click Sign in, get pushed to the Persona page, but intead I choose to add another email account, and do the email verification. Now I can choose which email account to sign in with from Persona. Should I go back to developer.mozilla.org and log in again, I will now be able to use either my gmail address or my work address to log in, without repeating the email verification process.

Using Persona authentication means that you are allowing a federated authentication solution to establish trust based on proof of control over a 3rd party account, and gaining the benefit that once a user is enrolled with BrowserID, they only have to click an approval (i.e. select the account to authenticate with).

This is what they've recommended and it's pretty quick and easy to set up, literally just create an account and log in down where it prompts you to in the history section at cubari.moe
