Are JWT token safe?

It's an encoded, URL-safe string that can contain an unlimited amount of data (unlike a cookie) and is cryptographically signed. When a server receives a JWT, it can guarantee the data it contains can be trusted because it's signed by the source. No middleman can modify a JWT once it's sent.

Can someone steal my JWT token?

JWT tokens provide secure access to an authenticated user, and attackers are always looking for ways to steal these tokens and quickly gain access by impersonating a consumer.

Why is JWT not secure?

JWT is a stateless session, so it does not need to be saved in a database in the server-side like cookies, it only exists in the client side. please notice that it is not encrypted it's just encoded which means you can use base64 decode and you will get the JSON object in clear.

Does JWT put your web app at risk?

No they are not. Also the same applies to sessions, sessions should be refreshed, too. To clean up, your application may null out the session or remove the persisted value from the data store. The result is the same; no more session.

Is JWT URL safe?

Because JWTs are just URL safe strings, they're easy to pass around via URL parameters, etc. They contain JSON-encoded data. This means you can have your JWT store as much JSON data as you want, and you can decode your token string into a JSON object. This makes them convenient for embedding information.

Why I haven't been using JWT tokens for Authentication

Is it safe to store JWT token in localStorage?

Cons: It's vulnerable to XSS attacks.

This means that the attacker can just take the access token that you stored in your localStorage . An XSS attack can happen from a third-party JavaScript code included in your website, like React, Vue, jQuery, Google Analytics, etc.

Is API token secure?

API keys are generally not considered secure; they are typically accessible to clients, making it easy for someone to steal an API key. Once the key is stolen, it has no expiration, so it may be used indefinitely, unless the project owner revokes or regenerates the key.

How long should a JWT 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.

What is wrong with JWT?

Drawbacks. There are major drawbacks to using JWT. First, it's a complicated standard and users are prone to get the settings wrong. If the settings are wrong, in the worst case it could mean that anyone can generate valid JWTs and impersonate anyone else.

How do I use JWT securely?

To keep them secure, you should always store JWTs inside an httpOnly cookie. This is a special kind of cookie that's only sent in HTTP requests to the server. It's never accessible (both for reading or writing) from JavaScript running in the browser.

Should JWT 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.
