making it easy to anonymously sign into sites that require your email address
At its core is a service for creating aliases for your real email address. Created on demand, they immediately start forwarding mail to your address, stopping if and when you decide to delete the alias.
Another important part of the project is a Firefox add-on, which allows you to create aliases directly from your browser, without having to visit the Janus website. All you need to do is right-click on an email field for an alias to be generated and automatically entered into it.
Janus and Mozilla Persona
The project features deep integration with Mozilla Persona on two different levels.
First, Janus uses Persona for signing in (meaning no new accounts or passwords for you to manage and remember).
Additionally, Janus is a Persona Identity Provider (IdP), which allows you to sign into Persona-enabled sites (RPs) with your alises without having to verify your email address (as you might need to do otherwise).
