Ever get bored with filling in registration forms? Ever lost your username or password for a website? If you think about it it's the wrong way around. It's like having a separate ID card for every shop when in reality we just have one ID card that works everywhere. OpenID gives you just that; a way to login to many websites using a single identity with a single password. You control what identity information you give to the website and you control which websites you trust and which you don't - OpenID puts you in control with a single password to remember. OpenID is an open specification for the web maintained by the OpenID foundation.
