Different between OAUth and OpenID

Initially I had confusion between OAuth and OpenID, so start using our search giant Google to find the solution.

Now I’m clear what is what.

OpenID:
It is only for Identification / Authentication. Here we need to prove oneself to the OpenID providers like who am I.

OAuth:
It is only Authorization; we are authorizing a third party service to access our personal information without providing our password.
