What is OAuth2 in Spring Security?
A) A protocol for authorization, allowing third-party applications limited access to a user’s resources
B) A database management tool
C) A password hashing algorithm
D) A method for data encryption
Answer:
A) A protocol for authorization, allowing third-party applications limited access to a user’s resources
Explanation:
OAuth2 (Open Authorization) is a widely-used protocol for authorization that allows third-party applications to access a user’s resources without exposing their credentials. It provides a secure way to grant limited access to resources on behalf of the user, typically by using access tokens.
Spring Security provides comprehensive support for OAuth2, enabling developers to easily integrate third-party login providers (like Google, Facebook, or GitHub) and build secure applications that leverage OAuth2 for authorization. OAuth2 is particularly useful in scenarios where applications need to access user data from external services, such as social media accounts, without directly handling user credentials.
