I personally prefer BrowserID. With the facebook/twitter logins popping up everywhere, you’re basically giving them all of your public info on a platter when you login using OpenAuth. With BrowserID all you need is an email address, and that’s all the participating site gets. No age, gender, your friends info etc. Just what you need to login, that’s all. But you won’t find many sites using BrowserID. That’s simply because the reason these sites have you login through facebook/twitter is simply that. They need to get your friends, your activities, your wall posts, etc… things they don’t necessarily need, but can certainly use. With BrowserID all they’d get is an email address, which doesn’t help them out a lot. Give BrowserID a try today.
