What is JWT expiration and how does it work?
An example of an AI chatbot conversation about JWT expiration and its significance in security.
What is JWT expiration and how does it work?
JWT expiration refers to the time limit set on a JSON Web Token (JWT) after which it is no longer valid. It helps enhance security by ensuring that tokens are not used indefinitely.
How do I set the expiration time for a JWT?
You can set the expiration time by including the 'exp' claim in the payload of the JWT. This claim should contain a timestamp indicating when the token will expire.
What happens if a JWT expires?
If a JWT expires, the server will reject any requests made with that token, requiring the user to authenticate again to obtain a new token.
Can I refresh an expired JWT?
Yes, you can implement a refresh token mechanism that allows users to obtain a new JWT without re-authenticating, as long as the refresh token is still valid.
