What is OAuth and how does OAuth work?
you must have used O Auth while logging in to social media or other websites, but you may not know that it was O Auth. So what is O Auth? O Auth means Open Authorization. It is an authentication protocol that helps in securely sharing user data with third party applications and services. Its primary use case is that when you log in to an application and that application needs access to your social media account, email account or any other online service, then O Auth is used.
How does O Auth work?
The first is user authentication. When you log in to a third party application and want to give access to that application, then you are not allowed to provide your login credentials. So instead of logging in there, you have to provide the login credentials of the original service provider. The second is authorization grant.
When you log in successfully, you are asked whether you want to give access to the third party application or not. You can allow it. Or you can deny it. Third is access token. If you allow it, the original service provider provides you with an access token. This token allows third party applications to access the user’s account but does not share your login credentials or sensitive information.
Fourth is access token. Third party applications can access user data using this access token, such as users profile information, photos, email addresses etc. Whatever things they can access are normally told to you. Before giving access, it will be written in it. In this way, Auth protects user privacy because the user does not share his sensitive credentials directly with the third party application.

There are many different versions of Auth, such as Auth 1.0, Auth 2.0 and Auth 2.0, among which Auth 2.0 is a major and modern version which is used more nowadays. Did you understand what Auth is?
