What are the best authentication methods for Java microservices?
The best authentication methods for Java microservices include OAuth2, JWT (JSON Web Tokens), and Basic Authentication. Each has its own use cases and benefits.
Can you explain how JWT works in microservices?
Sure! JWT is a compact, URL-safe means of representing claims to be transferred between two parties. It allows you to verify the token's authenticity and the user's identity.
What are the advantages of using OAuth2?
OAuth2 provides delegated access, allowing users to grant third-party applications limited access to their resources without sharing credentials.
Are there any security concerns I should be aware of?
Yes, common concerns include token expiration, secure storage of tokens, and ensuring HTTPS is used to prevent man-in-the-middle attacks.
