A normal web user may login and use to tens to hundreds of sites everyday. This is a hectic task and also one may remain in doubt as how his/her data is being used in each of these networks. To simplify this login system and to give users better control over their data, Mozilla has introduced a new product in the market, Persona.
Persona is a simple login system which can be deployed across multiple sites. So instead of logging in each of the networks, you just need to login one and you will be access all the networks with a single login and do more work. Also, for privacy freaks, those who really care how their data is being used, you just need to provide your email address to use Persona. You can enter rest of your info whenever you feel right.
Persona makes work easier for web publishers too. You just need to embed a few lines of code to make a Persona enabled site. Login is secure as well as convenient from users' point of view.
