Open ID is quickly getting acceptance on the web; today there is more than one billion Open ID facilitated user accounts.
According to an estimate, more than 50,000 websites are accommodating Open ID accounts for login.
Numerous large organizations are issuing and accepting Open IDs. These include some of the most well-reputed and established websites such as Google, Facebook, Yahoo, Microsoft, AOL, MySpace, Sears, Universal Music Group, France Telecom, Novell, Sun, and Telecom Italia, and many more.
Open ID is a manageable, distinct digital identity that users can employ on the Internet on all the websites that are accepting Open ID.
Now you can sign into any website that accepts the Open ID service with your Open ID account. An Open ID is a way of recognizing yourself regardless of which website you are visiting.
Open ID is like a driving license for the Internet. Open ID also gives you the capability to correlate the information with it like your email address, name, contact number, and home address.
Using Open ID you can also specify how much websites can learn about you using the information provided. So if you are using Open ID you do not have to enter similar information again and again for a website, your Open ID will manage that information for you and depending upon the preferences will provide that information to the requestioned website with your consent and approval.
