Well, it's 2 A.M. and I can't seem to shut my brain off as usual. I started thinking about how cool single sign-on is. As with all things that make your life easier, you sometimes miss the blindingly obvious pitfall associated with a signle sign on.

That being if your password is compromised then you expose yourself to identity theft on a grand scale. Systems such as Microsofts passport or Open ID make signing in to different websites easy, but even easier for criminals and general evil do-ers to take advantage of you putting all of your eggs in one basket.

Not only are you susceptible to attacks on sites you use, but also those you don't and you may never be any the wiser.

Do yourself a favour and remember, single sign-on belongs behind a firewall, and has no place in this crazy hi-tech world of identity theft and chicken rape.
