Techopedia Explains OpenID
The original authentication protocol for OpenID was developed by Brad Fitzpatrick in May of 2005 while he was working at Six Apart. OpenID was soon implemented on Fitzpatrick’s creations, LiveJournal and DeadJournal. OpenID allows users to sign in to thousands of websites without having to create new usernames and passwords. This provides convenience for the user and increases security, because user infromation and passwords are stored centrally. That means if one account is hacked, the hacker won't be able to retrieve a password that can be used to hack the same user's account on other sites.Advertisement
