JWT, or the JSON web token, is an Internet standard for creating data with an optical signature or payload. These tokens are then signed using a private secret or a public/private key.
While managing JWT tokens, some problems might occur during their authentication. Recently, many of our readers have been complaining about the JWT expired error.
If that’s something you’re having trouble with, read this post to learn how to fix it.
What does JWT has expired mean?
JWT provides a standard way of secure communication between two parties. Currently, it is used to access safe ways on API.
These tokens expire after a designated time to protect data integrity. The expiration time identifies the time after which the JWT token won’t be accepted for processing.
What happens when JWT expires?
A JWT token that doesn’t expire could cause harm. If stolen, someone can access and leak the user data.
After the token expires, you can use the refresh token to get a new JWT. Once the refresh token gets revoked, the operation will fail, and the user will have to log in again.
What to do after JWT expires?
Another thing you can try once you face the JWT expired error is making the system call another refresh token. This request will cause the expired JWT to pass, and the server will issue a new JWT, which the system can further use.
Make sure to use separate services to issue the refresh token as it won’t update the expiration of the existing JWT token.

How to check if the JWT token is expired or not?
There are two methods to do so. In the first one, you check the token expiration every time the Route changes and call the App component logout method.
And the second one requires you to dispatch the logout event to App component when the response status tells that the token is expired.
How to set an expiration time for the JWT token?
The JWT expiry date of a token can be configured while registering it. You can set the expiration time by calling the API Manager. To do so, you need to make a PUT request to the endpoint /api-manager/api/v3/access-tokens/{code}.
This was how you can fix the JWT expired error. Follow the steps mentioned above to fix the JSON web token error.
