What is OpenID?
With OpenID, a user can use an existing account to sign in to several websites without the need to create new passwords. Open ID enables the user to share their information and keep control over the details that they don’t wish to share with the website while they are signing in without using their credentials. The password is only provided to the identity provider of the user and that identity provider always confirms the identity to the website the user visits or the application that user accesses. It’s a secure credential management practice through which only the identity provider can see the credentials and no other website/application has access to the same.
