It depends. If you have multiple servers of keep the token between server restarts than you need to persist it somewhere. The database is usually an easy choice. If you have a single server and don’t care that your users have to sign in again after a restart, than you can just keep it in the memory.
Should JWT token be saved in DB?
Using JWT for SPA authentication
JWTs can be used as an authentication mechanism that does not require a database. The server can avoid using a database because the data store in the JWT sent to the client is safe.
Should I store refresh tokens in DB?
You can replace the refresh token on each refresh, but remember that you need to store all expired refresh tokens until their lifetime is over. From a security perspective it makes sense to create a new token, but it is a trade off between security and amount of data in your database.
Where should access tokens be stored?
Therefore, the access token should be stored on the web application server only. It should not be exposed to the browser, and it doesn’t need to, because the browser never makes any direct requests to the resource server.
Is JWT token secure?
The contents in a json web token (JWT) are not inherently secure, but there is a built-in feature for verifying token authenticity. A JWT is three hashes separated by periods. The third is the signature.
When should I use JWT tokens?
The tokens are designed to be compact, URL-safe, and usable especially in a web-browser single-sign-on (SSO) context. JWT claims can typically be used to pass identity of authenticated users between an identity provider and a service provider, or any other type of claims as required by business processes.
Should I store token in Redis?
2 Answers. TLDR: If you want the capability to revoke the token at some point, yes, store it in something fast like Redis. One of the well documented drawbacks of using JWT is that there’s no simple way to revoke a token if for example a user needs to be logged out or the token has been compromised.
When should I remove refresh token?
Yes you should. Because after logout when the user will login a new access token with a new refresh token will be issued. In that case, you should not keep your refresh token. Because whether you delete or not, on next login refresh token will be issued again (if your grant allows).
Should you encrypt refresh tokens?
Hence, the refresh token allows an application to autonomously obtain a new access token from the security token service, without user intervention. … Again, the application is responsible for storing these tokens securely. In practice, this comes down to encrypting the tokens before storing them on the device.
Store your access token in memory, and store the refresh token in the cookie: Link to this section
- Use the secure=true flag so it can only be sent over HTTPS.
- Use the SameSite=strict flag whenever possible to prevent CSRF.
What should be stored in JWT?

How long should JWT tokens last?
JWT Token has an expiration of 2 hours. The token is refreshed every hour by the client. 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.
Do JWT tokens expire?
The JWT access token is only valid for a finite period of time. Using an expired JWT will cause operations to fail. As you saw above, we are told how long a token is valid through expires_in. This value is normally 1200 seconds or 20 minutes.
