JWTs are well-suited for server-to-server or microservice-to-microservice communication scenarios within a backend architecture. In this context, JWTs serve as a means of securely transmitting information between services for authorization and authentication purposes.JWTs are ideal for stateless, distributed systems with a focus on scalability and single sign-on, while session-based approaches are more appropriate for applications that prioritise server-side control, robust session management, and sensitive data protection.Information exchange: JWTs are a good way of securely transmitting information between parties because they can be signed, which means you can be certain that the senders are who they say they are. Additionally, the structure of a JWT allows you to verify that the content hasn't been tampered with.
Why is JWT more secure : Advantages of JWT
Security: JWTs are digitally signed, ensuring data integrity and preventing tampering. Using encryption algorithms enhances the security further. Cross-Domain Communication: JWTs can be used across different domains or microservices since they don't rely on cookies or server-side sessions.
Why is JWT the best
JWT is usually signed to protect against data manipulation or alteration. With this, the data can be easily read or decoded. So, you can't include sensitive information such as the user's record or any identifier because the data is not encrypted.
Why avoid JWT : Problems with JWT
JWT is named pretty well, but fails miserably at the first problem: invalidation, or How do you log out the user The answer is, you don't. You can't. You (the server) can tell the user's client software to forget their JWT and hope they'll do it, but you can never be sure.
The criticisms of JWT seem to fall into two categories: (1) Criticizing vulnerabilities in particular JWT libraries, as in this article. (2) Generally criticizing the practice of using any "stateless" client tokens. Because there's no great way to revoke them early while remaining stateless, etc. The JWT app type will be completely deprecated as of June 2023. New and current users have 12 months to migrate their JWT based solutions to the Server-to-Server OAuth app type. Action recommended: Create Server-to-Server OAuth app types to replace existing JWT app types.
Why JWTs are bad for authentication
Because JWTs are frequently not encrypted, anyone who can execute a man-in-the-middle attack and sniff the JWT now has access to your authentication credentials. This is made easier because the MITM attack only has to be carried out on the server-client connection.So why is JWT dangerous for user authentication The biggest problem with JWT is the token revoke problem. Since it continues to work until it expires, the server has no easy way to revoke it. Below are some use cases that'd make this dangerous.A: JWT apps were deprecated on a rolling basis starting Sept 8, 2023. If your app was deprecated and you need more time, you can re-activate it and get a one-time extension until November 10, 2023. After November 10th, the app will be permanently removed and the credentials will be revoked. Disadvantages of JWT Authentication:
Limited Token Expiry Control: Once issued, JWTs remain valid until they expire. Revoking a JWT before expiration requires additional complexity, such as token blacklisting. Security Risks: If the secret key used to sign JWTs is compromised, attackers can create forged tokens.
