PHPMaster.com: Authenticate Users with Mozilla Persona
On PHPMaster.com there's a new tutorial from Vito Tardia about using the Mozilla Persona authentication system in your PHP application - an abstracted authentication system that keeps only a token representing the user in your system.
Mozilla Persona is built upon the BrowserID technology also developed by Mozilla. You can find an expanded explanation of the concepts in the article How BrowserID Works by Lloyd Hilaiel. [...] An email address is an identity and it's verified by the email provider [then the] authentication takes place in the browser.
