WCF Restfull Service or Web API Token

OAuth is Open Authentication which is an open standard for authorization. You may have seen most of the apps and websites nowadays provides options to Sign in using facebook or using Gmail. So rather than creating profile for every account and remembering passwords for every websites, It would be easier for a user to just sign in using their existing facbook or gmail credentials. This can be done using OAuth.

 

OAuth doesn’t share password data but instead uses authorization tokens to prove an identity between consumers and service providers. OAuth is an authentication protocol that allows you to approve one application interacting with another on your behalf without giving away your password.
