OAuth is an open standard that allows users to grant third-party access to their account information without sharing their passwords. It works by using tokens to authorize specific types of access, allowing users to securely share data between websites or applications. OAuth is widely adopted and brings interconnectivity by allowing users to log into one service using their login credentials from another participating service.
