Do JSON Web Tokens expire?
The JWT access token is only valid for a finite period of time. Using an expired JWT will cause operations to fail.
How long is a JSON web token?
Each of these can be at most 8KB in length, but together can be more than 8KB in total. Requests containing a request line or header line longer than 8KB will be dropped by the router without being dispatched.
How long should session tokens last?
The access tokens may last anywhere from the current application session to a couple weeks. When the access token expires, the application will be forced to make the user sign in again, so that you as the service know the user is continually involved in re-authorizing the application.
How long should JWT refresh token last?
Authentication is implemented through JWT access tokens along with refresh tokens. The API returns a short-lived token (JWT), which expires in 15 minutes, and in HTTP cookies, the refresh token expires in 7 days.
How do I know if my token is expired?
This can be done using the following steps:
- convert expires_in to an expire time (epoch, RFC-3339/ISO-8601 datetime, etc.)
- store the expire time.
- 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 do tokens expire?
Go to the Settings tab. Under Refresh Token Expiration, enable Absolute Expiration. When enabled, a refresh token will expire based on an absolute lifetime, after which the token can no longer be used.
Is JWT better than session?
In modern web applications, JWTs are widely used as it scales better than that of a session-cookie based because tokens are stored on the client-side while the session uses the server memory to store user data, and this might be an issue when a large number of users are accessing the application at once.
What is JSON Web Token used for?
JWT, or JSON Web Token, is an open standard used to share security information between two parties — a client and a server. Each JWT contains encoded JSON objects, including a set of claims. JWTs are signed using a cryptographic algorithm to ensure that the claims cannot be altered after the token is issued.
Where are refresh tokens stored?
You can store encrypted tokens securely in HttpOnly cookies. If you worry about long-living Refresh Token. You can skip storing it and not use it at all. Just keep Access Token in memory and do silent sign-in when Access Token expires.

What if refresh token is stolen?
If the refresh token can be stolen, then so can the access token. With such an access token, the attacker can start making API calls. To make matters even more complicated, access tokens are often self-contained JWT tokens. Such tokens contain all the information needed for the API to make security decisions.
How do I make my JWT Token not expire?
There are three ways:
- Changing the secret key. This will revoke all tokens of all users, which is not acceptable.

- Store the revoked JWT tokens in Redis.
How do I make my JWT Token never expire?
- retrieve the user info and Check whether the token is in his User database. If so allow.

- When user changes his password, remove all tokens from his user database and ask him to login again.
How can I get my JWT Token to expire?
The most common solution is to reduce the duration of the JWT and revoke the refresh token so that the user can’t generate a new JWT. With this setup, the JWT’s expiration duration is set to something short (5-10 minutes) and the refresh token is set to something long (2 weeks or 2 months).
