Sign-in with Facebook now here!

This is gonna be quick – I’m getting ready to head out to a concert. I just added a new feature on the site… the ability to sign-in with Facebook.

Here’s the deal – *no one* wants to have to create another new username/password for every random site they stumble across on the interwebs. So Facebook (and lots of other large web properties) offer themselves as a trusted source of authentication. That means you can use your Facebook credentials to sign into Zweigmodel.com.

A couple of quick notes:

You are signing into Facebook — YOU ARE NOT providing your FB credentials to me. Check out the URL, it’s the FB url. Once FB verifies who you are, they redirect you to my site, and there is a brief handshake between me and FB… something that goes like – “yep, this is a valid Facebook user and here are a few pieces of info about him/her”. It then passes me your first name, last name, email address and a few other pieces of data. I’m not storing them yet… I soon will for tracking/metrics/etc. Don’t worry – 1500 people and not one spam.

I will be adding a few other providers soon… namely, Google, MSN, Yahoo! and OpenID. Between those four (plus Facebook) – I think I’ll have the whole planet covered.

And, for you – there’ll be one less username/password to remember.

QUESTION: Will anyone be impacted by this? Is there anyone who *doesn’t* have credentials with one of those five services? Man, I’ve got all five… and I don’t think I’m alone in that regard.

I’d love to hear your thoughts.

Regards,

Kevin
