What to do when JWT expired?

What to do when JWT expired?

There are three ways:

1. Changing the secret key. This will revoke all tokens of all users, which is not acceptable.
2. Make each user has his own secret and just change the secret of a specified user. Now the RESTful backend is not stateless anymore.
3. Store the revoked JWT tokens in Redis.

When should I refresh JWT?

Is a Refresh Token really necessary when using JWT token authentication?

1. JWT Token has an expiration of 2 hours.
2. The token is refreshed every hour by the client.
3. If the user token is not refreshed (user is inactive and the app is not open) and expires, they will need to log in whenever they want to resume.

How do I renew my expired JWT token?

To refresh the token, your API needs a new endpoint that receives a valid, not expired JWT and returns the same signed JWT with the new expiration field. Then the web application will store the token somewhere.

Why is my JWT expired?

The JWT is no longer valid because more than two hours have passed since the IAT claim was performed. If you are using the EXP claim, verify that the expiration time is set between 10 minutes and two hours. Make sure to use UTC time when generating the value for the IAT claim.

How do you check if a token is expired?

This can be done using the following steps:

1. convert expires_in to an expire time (epoch, RFC-3339/ISO-8601 datetime, etc.)
2. store the expire time.
3. on each resource request, check the current time against the expire time and make a token refresh request before the resource request if the access_token has expired.

How are JWT tokens used in a RESTful API?

I’m building a RESTful API that uses JWT tokens for user authentication (issued by a login endpoint and sent in all headers afterwards), and the tokens need to be refreshed after a fixed amount of time (invoking a renew endpoint, which returns a renewed token).

Is there a way to expire a JWT?

If the user wishes to log out or expire existing tokens, they simply increment the jwt_version field. When generating a new JWT, encode the jwt_version into the JWT payload, optionally incrementing the value beforehand if the new JWT should replace all others.

How can I Revoke my JWT access token?

Below are the steps to do revoke your JWT access token: 1) When you do login, send 2 tokens (Access token, Refresh token) in response to client . 2) Access token will have less expiry time and Refresh will have long expiry time . 3) Client (Front end) will store refresh token in his local storage and access token in cookies.

What happens when you renew a Web Token?

The new token will replace the existing in future calls. As you can see, this reduces the frequent refresh token requests. If user closes the browser/app before the renew token call is triggered, the previous token will expire in time and user will have to re-login.
