Why not to use JWT?

Problems with JWT

You can't. You (the server) can tell the user's client software to forget their JWT and hope they'll do it, but you can never be sure. Well, you could keep a list of tokens that are no longer valid - that is, the user has logged out and the token should be ignored.

Is token more secure than session?

The main difference between the session and token authentication is that the authentication details are stored on the server side in session authentication and on the user side in token authentication. Token authentication is more secure than session authentication because a token cannot be tampered with.

Is session authentication safe?

A session ID is an opaque reference to actual session data stored on the server. It is safe insofar as it is random enough to not be guessed easily, and the data is safe because it is not directly accessible by or beholden to the front-end. The session ID is stored in a cookie to simplify authenticated requests.

When should JWT be used?

JWT also allows us to use the same JSON Web Token in multiple servers that you can run without running into problems where one server has a certain session, and the other server doesn't. Most modern web applications use JWT for authentication reasons like scalability and mobile device authentication.

Are cookies or sessions more secure?

Sessions are more secured compared to cookies, as they save data in encrypted form. Cookies are not secure, as data is stored in a text file, and if any unauthorized user gets access to our system, he can temper the data.

What is better than JWT?

JSON web token (JWT) is the most popular token-based authentication. However, many security threats have been exposed in recent years, causing people to migrate to other types of tokens. Platform Agnostic Security Token or PASETO is one such token which is being accepted as the best secured alternative for JWT.

What are disadvantages of session?

Disadvantages: 1. Performance overhead in case of large number of user, because of session data stored in server memory. 2. Overhead involved in serializing and De-Serializing session data because in case of StateServer and SQLServer session mode we need to serialize the object before store.

Should I use sessions?

Use sessions only if the data is too big for cookies or if the data is so big that it would decrease the performance if you used cookies.

Should I use session variables?

If the answer is "the current value", session variables may be useful. An example would be a shopping cart: you don't expect things to be removed from the shopping cart as you go back through the history. It's always in its current state. If the answer is "a previous value", you should not be using session variables.

Is JWT obsolete?

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.

Is JWT better than OAuth?

OAuth2 vs JWT, Both systems have their particular use cases and advantages. While JWT is excellent for API authentication and server-to-server authorization, OAuth 2.0 takes the lead in session management.

Which is better OAuth or JWT?

JWT is mainly used for APIs while OAuth can be used for web, browser, API, and various apps or resources. JWT token vs oauth token: JWT defines a token format while OAuth deals in defining authorization protocols. JWT is simple and easy to learn from the initial stage while OAuth is complex.

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 enough for security?

Using JWTs securely goes beyond verifying their signatures. Apart from the signature, the JWT can contain a few other security-related properties. These properties come in the form of reserved claims that can be included in the body of the JWT. The most crucial security claim is the "exp" claim.

Does Google use JWT for authentication?

Can I store token in session?

Web applications need to store tokens to help manage user sessions. Because the browser/server relationship is “stateless,” every request would otherwise require reauthentication. As a web developer, you typically have two options for client-side token storage: local storage (aka localStorage) and cookies.

How long does a session token last?

Non-persistent session tokens have a Max Inactive Time of 24 hours whereas persistent session tokens have a Max Inactive Time of 90 days. Any time the SSO session token is used within its validity period, the validity period is extended another 24 hours or 90 days.

Why do we need a session token?

The session token, also known as a sessionID, is an encrypted, unique string that identifies the specific session instance. If the session token is known to a protected resource such as an application, the application can access the session and all user information contained in it.

Can session be hacked?

After a user starts a session such as logging into a banking website, an attacker can hijack it. In order to hijack a session, the attacker needs to have substantial knowledge of the user's cookie session. Although any session can be hacked, it is more common in browser sessions on web applications.

What is the safest authentication method?

1. Biometric Authentication Methods. Biometric authentication relies on the unique biological traits of a user in order to verify their identity. This makes biometrics one of the most secure authentication methods as of today.

Can session be hijacked?

Session hijacking is a technique used by hackers to gain access to a target's computer or online accounts. In a session hijacking attack, a hacker takes control of a user's browsing session to gain access to their personal information and passwords.

Is JWT good for authentication or authorization?

Both API key and JWT are used for authentication and authorization, but they do it differently. Authentication allows the user or application to use one or more methods of the API. Authorization defines how they can use those methods.

Which JWT algorithm is best?

While both HS256 and RS256 can be used to allow verification the integrity of JWTs, the recommended algorithm at this time is RS256. A signature must ensure authenticity, which means that the JWT content is the same as that generated by the sender. Both HS256 and RS256 algorithms ensure JWT authenticity.

Does JWT put your web app at risk?

JWT is not fully immune to attacks. The biggest threat facing JWTs is the risk of tokens being stolen. When access token and refresh token are stolen, it will be possible to impersonate their owner. In case of using JWT without a refresh token, the problem will be resolved as soon as the access token expires.

Is it safe to store JWT in session storage?

A JWT needs to be stored in a safe place inside the user's browser. Any way,you shouldn't store a JWT in local storage (or session storage). If you store it in a LocalStorage/SessionStorage then it can be easily grabbed by an XSS attack.

What should not be stored in session?

Things like Database Data such as User Rows should not be stored in the session and you should create a separate cache mechanism to do this for you.

What is the best way to store JWT in client?

The HttpOnly tag for Cookie is one of solutions to defend XSS. The HttpOnly tag will restrict users to manipulate the Cookie by JavaScript. It's the reason people recommends us to save JWT in the HttpOnly Cookie instead of the localStorage.

Should email be stored in JWT?

'JWT Claims set' of a JWT request should contain an email address, which, according to the respective article, is used as the unique identifier for a user unless an external ID is received.

Does Amazon use JWT?

After a user logs in, an Amazon Cognito user pool returns a JWT. The JWT is a base64url-encoded JSON string ("claims") that contains information about the user. Amazon Cognito returns three tokens: the ID token, the access token, and the refresh token.

Is it safe to decode JWT in frontend?

JWT decode only look for public part so it is totally safe to do that in your front-end code.

Should I Always allow session cookies?

Should I always allow session cookies? Session cookies are essential for a website's functionalities or for it to deliver a service that it intends to. They are also exempt from consent requirements under privacy regulations like the GDPR.

Should you store sessions in cookies?

Cookies store it directly on the client. Sessions use a cookie as a key of sorts, to associate with the data that is stored on the server side. It is preferred to use sessions because the actual values are hidden from the client, and you control when the data expires and becomes invalid.

What is the best practice to prevent cookies?

Can I Stop Receiving Cookies? One way to do that is by browsing in “Private" mode (for Safari or Firefox) or “Incognito” (for Chrome). Browsing this way doesn't keep your internet service provider or a web server from knowing what you're doing online, but it does keep cookies from working.

What is difference between session token and JWT token?

One of the simplest ways is to return both a session_token and a JWT when a user starts a session. The session_token is a static value that is good for the lifetime of the session (stored server-side), while the JWT has its own, shorter-lived expiry.

What replaces JWT?

PASETO is designed as a replacement for JWTs, particularly their use in protocols such as OAuth and OpenID Connect.

Can someone steal your JWT?

JWTs can be best and secure but it is very secured only if it is used in the right way. Attacks like token stealing, XSS, Middle man attacks are still possible.

What is the lifespan of JWT token?

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.

Can JWT be cracked?

Cracking a JWT signed with weak keys is possible via brute force attacks.

Why is JWT more secure?

When JWT is used for simple client-to-server identification there is no need for signing or asymmetric encryption. JWT can be encrypted with AES which is fast and supersecure. If the server can decrypt it, it means the server is the one who encrypted it. Summary: non-encrypted JWT is not secure.

Which is more secure JWT or OAuth?

OAuth2 vs JWT, Both systems have their particular use cases and advantages. While JWT is excellent for API authentication and server-to-server authorization, OAuth 2.0 takes the lead in session management.

Is JWT really secure?

The general opinion is that they're good for being used as ID Tokens or Access Tokens and that they're secure — as the tokens are usually signed or even encrypted. You have to remember though, that JWT is not a protocol but merely a message format.

Can someone steal my JWT token?

The token can be used to access the application

If your JWT is stolen or compromised, then the attacker has full access to your account. The attacker can send requests to applications, pretending to be you, and can make potentially harmful changes.

Should I use OAuth or JWT?

JWT is mainly used for APIs while OAuth can be used for web, browser, API, and various apps or resources. JWT token vs oauth token: JWT defines a token format while OAuth deals in defining authorization protocols. JWT is simple and easy to learn from the initial stage while OAuth is complex.

Do banks use JWT?

The finance app (client) can now request protected resources from the bank's resource server using the JWT access token. The bank's resource server, upon recognizing a valid JWT access token, returns the protected resources on request.

Why use JWT over cookies?

JWT offers many features, and puts them in a standard so they can be used between parties. A JWT can act as a signed assertion of some facts in many different places. A cookie, no matter what data you put in it or if you sign it, only really makes sense to use between a browser and a specific back end.
