BrowserID explains how BrowserID works for end users, developers, and identity providers. It’s a universal login system that is not limited to Firefox; it will work in any web browser and supporting site. You sign up for the site by using the demo site, MyFavoriteBeer. When you arrive at the site, click the “Sign in” button and go through the sign-in process. After you verify your email address, you’re set to go.
You use the same process for other BrowserID-supporting sites, which is similar to OpenID. No other supporting sites, as of this writing, are listed. Since most of us visit the same trusted sites on a regular basis, BrowserID uses what’s called Verified Email Protocol, which is “a way for users to prove to a website that they control an email address, through the web browser“.
Even with offline password managers, website log-ins can be a hassle when those managers don’t work like they’re supposed to. BrowserID could be a great alternative to web-centric systems that act as an identity token especially for sites that you trust and visit on a regular basis.
