How is JWT used in microservices architecture?
JWT, or JSON Web Token, is commonly used in microservices for authentication and information exchange. It allows services to verify the identity of users and securely transmit data.
What are the benefits of using JWT over traditional session-based authentication?
JWTs are stateless, meaning they don't require server-side storage, which enhances scalability. They also allow for cross-domain authentication and can carry more information.
Are there any security concerns I should be aware of when using JWT?
Yes, some concerns include token expiration, secure storage of tokens, and ensuring the tokens are signed with a strong algorithm to prevent tampering.
How do I implement JWT in my microservices?
You can implement JWT by generating a token upon user login, including user information and signing it. Each microservice can then validate the token on incoming requests.
