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 tokens in database?
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.
What should be stored in a JWT token?
- Registered claims like sub , iss , exp or nbf.
- Public claims with public names or names registered by IANA which contain values that should be unique like email , address or phone_number . See full list.
- Private claims to use in your own context and values can collision.

Where should I store the access token?
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.
Should tokens be encrypted?
As we said above, JWT are not encrypted by default, so care must be taken with the information included inside the token. If you need to include sensitive information inside a token, then encrypted JWT must be used.
How do I store my JWT token react?
Storing JWT Token
We can store it as a client-side cookie or in a localStorage or sessionStorage. There are pros and cons in each option but for this app, we’ll store it in sessionStorage.
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.
Where do you store JWT token spring boots?
1 Answer. It is stored in-memory by default.
Where should you store JWT token?
A JWT needs to be stored in a safe place inside the user’s browser. If you store it inside localStorage, it’s accessible by any script inside your page. This is as bad as it sounds; an XSS attack could give an external attacker access to the token.
Can JWT token be forged?
One of the ways that attackers can forge their own tokens is by tampering with the alg field of the header. If the application does not restrict the algorithm type used in the JWT, an attacker can specify which algorithm to use, which could compromise the security of the token. JWT supports a “none” algorithm.
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.
Should you store tokens in local storage?
Most developers are afraid of storing tokens in LocalStorage due to XSS attacks. While LocalStorage is easy to access, the problem actually runs a lot deeper. In this article, we investigate how an attacker can bypass even the most advanced mechanisms to obtain access tokens through an XSS attack.
Although cookies still have some vulnerabilities, it’s preferable compared to localStorage whenever possible. … Both localStorage and cookies are vulnerable to XSS attacks but it’s harder for the attacker to do the attack when you’re using httpOnly cookies.
