OAuth (Open Authorization) is an open standard protocol that allows secure authorization between different applications. It is widely used in modern web development to grant limited access to user data without exposing their login credentials. As an integral part of the authentication process, OAuth plays a crucial role in ensuring the security and privacy of user information.
In order to excel in an OAuth interview, it is important to have a strong understanding of the protocol and its implementation. This article presents a comprehensive list of OAuth interview questions to help you prepare for your next job interview in the field of web development or security.
