OAuth2 is a popular authorization framework that allows systems to integrate by delegating access to data. While widely used, many people do not fully understand how it works. OAuth2 simplifies the process for client applications while providing robust security measures to protect against various vulnerabilities. Personal Access Tokens offer a more secure alternative to sharing plain credentials, but managing them can become cumbersome. Through OAuth2, users can grant permissions to third-party applications to access their data, allowing for decentralized control and expanding the functionality of resource servers like Git repositories. The Authorization Server plays a crucial role in handling security nuances and issuing access tokens, ensuring the security of the OAuth2 process.
