OAuth

OAuth is a great idea. As Six Apart says in their announcement of support...

Right now, if you want Flickr to post to your TypePad blog, or you want to connect a client to update both your Twitter account and your LiveJournal, you have to give them the password to your account, giving a third-party free reign on your site. Even worse, on some other services, the password for an account used for blogging or other applications is the same login that controls extremely sensitive information like your email account or credit card systems.

OAuth aims to standardize the way in which different consumer systems share data. The goal is to allow a person to give an application access to do some things on your accounts at other sites, but not everything. It’s role-based authorization for APIs.

Right now you give Facebook your Yahoo username and password so they can check so you can connect with Yahoo Mail contacts that are also on Facebook. That’s fine and dandy as long as Facebook doesn’t decide to do anything malicious with your account (like send an email to everyone, pretending to be you). Or as long as their systems aren’t compromised.

What OAuth wants to do is allow you to give Facebook permission to see your Hotmail contacts, but not to send them email, to change your contacts, or to read your mail.

At IMified, we’re looking into the specification and we’ll be implementing support in our apps. When you give us access to post to your Google Calendar, you shouldn’t have to trust us that we won’t also be reading your email. I mean, you can trust us, but you shouldn’t have to.
