OAuth Insights

What is OAuth?

OAuth (Open Authorization) is an open standard authorization protocol or framework that enables third-party applications to obtain limited access to a user's resources on a resource server without exposing the user's credentials (username and password). It is commonly used to allow users to log in to websites or applications using their accounts from other services (like Google, Facebook, or Twitter) and to grant third-party applications access to specific data or functionalities without giving them full control over the user's account.
