APIs are crucial for many applications but need protection from misuse. OAuth2 provides a secure method for delegating access to resources without sharing original credentials. It leverages the expertise embedded in its standards to mitigate security risks and offers various flows (grants) to cater to different use cases. OAuth2 is extensible and widely supported across modern programming languages. While alternatives like API keys exist, OAuth2 offers richer functionality and greater security for many applications.
