What are JWT authentication flows?

Can you explain what JWT authentication flows are?

JWT (JSON Web Token) authentication flows are methods for securely transmitting information between parties as a JSON object. They are commonly used for user authentication and information exchange.

How does the JWT flow work in a typical web application?

In a typical web application, a user logs in with their credentials, and the server generates a JWT. This token is then sent to the client, which stores it and includes it in the header of subsequent requests to authenticate the user.

What are the advantages of using JWT for authentication?

JWTs are stateless, meaning they don't require server-side storage, and they can be easily transmitted across different domains. They also allow for scalability and can carry additional information.

Are there any security concerns I should be aware of with JWT?

Yes, some concerns include token expiration, secure storage of tokens, and ensuring the tokens are signed properly to prevent tampering.
