Should I use JWT with cookies?

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.

Is JWT same as cookie?

JWT is simply a token format. A cookie is an HTTP state management mechanism really. As demonstrated, a web cookie can contain JWT and can be stored within your browser's Cookies storage. So, we need to stop comparing JWT vs Cookie.

Are cookies better than JWT?

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.

Is JWT a header?

The header typically consists of two parts: the type of the token, which is JWT, and the algorithm that is used, such as HMAC SHA256 or RSA SHA256. It is Base64Url encoded to form the first part of the JWT. The payload contains the claims.

Should I store JWT in cookie or local storage?

Both cookies and localStorage are vulnerable to XSS attacks. However, cookie-based token storage is more likely to mitigate these types of attacks if implemented securely. The OWASP community recommends storing tokens using cookies because of its many secure configuration options.

Can I send JWT in a cookie?

Cookies. The server side can send the JWT token to the browser through a cookie, and the browser will automatically bring the JWT token in the cookie header when requesting the server-side interface, and the server side can verify the JWT token in the cookie header to achieve authentication.

What is cookies vs bearer token?

Cookies are always present once authenticated, while the Bearer token may be available only on some requests depending on the application. Note that this check only checks authentication type. It doesn't authenticate.

What are the 3 types of HTTP cookies?

There are three types of computer cookies: session, persistent, and third-party.

What is the difference between cookie and auth bearer?

The biggest difference between bearer tokens and cookies is that the browser will automatically send cookies, where bearer tokens need to be added explicitly to the HTTP request. This feature makes cookies a good way to secure websites, where a user logs in and navigates between pages using links.

Why JWT is not good for sessions?

Although JWT does eliminate the database lookup, it introduces security issues and other complexities while doing so. Security is binary—either it's secure or it's not. Thus making it dangerous to use JWT for user sessions.

What are the disadvantages of cookie based authentication?

Limitations of cookie-based authentication

It is vulnerable to Cross-site request forgery attack. It often needs other security measures such as CSRF tokens for protection. You need to store the session data in a database or keep it in memory on the server.

Which JWT algorithm is best?

The option with the best security and performance is EdDSA, though ES256 (The Elliptic Curve Digital Signature Algorithm (ECDSA) using P-256 and SHA-256) is also a good choice. The most widely used option, supported by most technology stacks, is RS256 (RSASSA-PKCS1-v1_5 using SHA-256).

What is the difference between JWT and bearer header?

A JWT is a convenient way to encode and verify claims. A Bearer Token is just a string, potentially arbitrary, that is used for authorization.

Where does JWT token go in header?

The first option is to add a header. Under the Headers tab, add a key called Authorization with the value Bearer <your-jwt-token> . Use the double curly brace syntax to swap in your token's variable value.

Is JWT same as bearer?

In essence, a JSON Web Token (JWT) is a bearer token. It's a particular implementation which has been specified and standardised. JWT in particular uses cryptography to encode a timestamp and some other parameters. This way, you can check if it's valid by just decrypting it, without hitting a DB.

Should you use cookies for authentication?

Using cookies in authentication makes your application stateful. This will be efficient in tracking and personalizing the state of a user. Cookies are small in size thus making them efficient to store on the client-side.

Should I use CSRF with JWT?

If our stateless API uses token-based authentication, such as JWT, we don't need CSRF protection, and we must disable it as we saw earlier. However, if our stateless API uses a session cookie authentication, we need to enable CSRF protection as we'll see next.

Is that good idea to use cookie in rest APIS?

However, cookies should not be used by a REST API if they are meant to maintain a client session on the server, such as a Session Token . This would violate the statelessness of the REST endpoint, as the server is required to know the state of each client in order to provide them with the requested resources.

What is the difference between cookie and Authorization header?

Cookies can be marked as "http-only" and thus can't be easily stolen by JavaScript. A header even has to be set by JavaScript, thus the auth token has to be accessible from within JavaScript. But yet, people use auth-headers to submit their auth-tokens from an untrusted client JavaScript to the server.

Do cookies bypass 2FA?

Phishing attacks have become more sophisticated and attackers are finding ways to bypass 2FA. The reason why is because of the delicious cookies stored in your browser. Session cookies are a way to show the server that the user has already authenticated. This includes passing the 2FA challenge.

What is cookies vs bearer token?

Cookies are always present once authenticated, while the Bearer token may be available only on some requests depending on the application. Note that this check only checks authentication type. It doesn't authenticate.

Is JWT outdated?

JWT Deprecation - The JWT app type will be completely deprecated as of June 2023. New and current users will have 12 months to migrate their JWT based solutions to the server-to-server OAuth app type.

Should JWT be in frontend or backend?

You should implement it on both backend / frontend. The Front end should have a UI to get the login / password entered by the user.

Is JWT bad for authentication?

JWTs can be used in various ways: Authentication: When a user successfully logs in using their credentials, an ID token is returned. According to the OpenID Connect (OIDC) specs, an ID token is always a JWT.

Is JWT vulnerable to XSS?

The risk of information loss using JWT token of storing structured information in local storage that is sent over the network in a serialized form, which usually happens in cookies or browser local storage. Local storage - the method is dangerous because it is susceptible to attacks such as XSS.

Is CSRF possible without cookies?

CSRF tokens prevent CSRF because without a token, an attacker cannot create valid requests to the backend server. For the Synchronised Token Pattern, CSRF tokens should not be transmitted using cookies. The CSRF token can be transmitted to the client as part of a response payload, such as a HTML or JSON response.

Should I use OAuth or JWT?

JWT is suitable for stateless applications, as it allows the application to authenticate users and authorize access to resources without maintaining a session state on the server. OAuth, on the other hand, maintains a session state on the server and uses a unique token to grant access to the user's resources.
