The JWT app type will be completely deprecated as of June 2023 (2024)

FAQs

Is JWT being deprecated? ›

Q: When will the JWT deprecation start? A: Zoom will disable the ability to create new JWT apps on June 1, 2023. The projected end-of-life for JWT apps will be September 1, 2023. New and current users have until September 1 to migrate their JWT-based solutions to the new server-to-server OAuth or OAuth app types.

All apps created for third-party usage must use our OAuth app type. A JWT app is a type of server-to-server authenticated app, which allows users as well as other apps to consume its services.

OAuth2, Passport, Spring Security, Auth0, and Keycloak are the most popular alternatives and competitors to JSON Web Token.

You can definitely use JWT tokens securely, however, you should probably not implement them from scratch since it can become complicated to secure them extensively without going down a rabbit hole.

Only one JWT app can be created per master Zoom account, hence cannot be deleted and recreated.

JWT can be used as an access token to prevent unwanted access to a protected resource. They're often used as Bearer tokens, which the API will decode and validate before sending a response.

Information exchange: JWTs are a good way of securely transmitting information between parties because they can be signed, which means you can be certain that the senders are who they say they are. Additionally, the structure of a JWT allows you to verify that the content hasn't been tampered with.

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.

Secure: Opaque tokens do not contain any user information, making them more secure than JWT tokens. Flexible: Opaque tokens can be customized to store additional user information in the authorization server, which can be retrieved by the resource server when needed.

The main difference between JWTs and opaque tokens is that an unencrypted JWT can be interpreted by anybody that holds the token, whereas opaque tokens cannot. An unencrypted JWT consists of three parts: a header, a payload, and a signature.

Why JWTs are bad for authentication? ›

The biggest problem with JWTs is that the token will continue to work until it expires, and the server has no easy way to revoke it. This could be extremely dangerous in situations such as the following: Logout doesn't actually log you out of the system.

With some Google APIs, you can make authorized API calls using a signed JWT instead of using OAuth 2.0, which can save you a network request.

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.

You should store the refresh tokens that you've given out in a table and when the user logs out, flag the token as revoked and then when you give a new access token out, verify that the refresh token hasn't been revoked.

JWT tokens cannot be revoked easily unless you check the token against an online database. However, one option that you can use with JWT is instead of storing active tokens in the database, the database can store revoked token instead.

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.

The signed JWT acts effectively as a temporary user credential, that replaces the permanent credential wich is the username and password combination.

Yes, it is bad practice and a security problem.

Email addresses are PII (personally identifiable information). Like all other PII, email addresses should never be stored unencrypted at rest; doing so is inherently insecure.

It is mostly used for authentication, authorization, and information exchange. JSON Web tokens are made of three parts separated by dots (.)

What is the problem with JWT? ›

Security is binary—it is either secure or not. As a result, using JWT for user sessions is dangerous. The biggest problem with JWTs is that the token will continue to work until it expires, and the server has no easy way to revoke it.

Secure: Opaque tokens do not contain any user information, making them more secure than JWT tokens. Flexible: Opaque tokens can be customized to store additional user information in the authorization server, which can be retrieved by the resource server when needed.

JWT is used for AUTHORIZATION, not AUTHENTICATION. In authentication, we take in a username and password and make sure it's correct (logging in). In authorization, we make sure the user who is sending requests to your server is the same user who logged in during authentication.

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 token expiration important? A JWT token that never expires is dangerous if the token is stolen then someone can always access the user's data. Quoted from JWT RFC (RFC 7519): The “exp” (expiration time) claim identifies the expiration time on or after which the JWT MUST NOT be accepted for processing.

Expiration only happens for web apps, not for native mobile apps, because native apps never expire. Revoking only happens when (1) uses click the logout button on the website or native Apps;(2) users reset their passwords; (3) users revoke their tokens explicitly in the administration panel.

JsonWebToken is an open-source project that aims to create web tokens. The vulnerability, tracked as CVE-2022-23529, allows attackers to bypass the verification of JWT tokens, potentially leading to remote code execution (RCE) on a server.

PASETO is more secure than JWT and offers a simpler implementation. As a result, many developer communities started accepting it as a better alternative to JWT. Now that you too know the advantages of using PASETO over JWT, what are you going to use for your next project ?

Don't Trust All the Claims

Claims in a JWT represent pieces of information asserted by the authorization server. The token is usually signed, so its recipient can verify the signature and thus trust the values of the payload's claims. You should be wary, however, when dealing with some claims in the token's header.

The main difference between API Key auth and JWT token auth is that the JWT Token is self-contained - the information asserted by the token is in the token. Whereas with an API Key the asserted information is stored in an external system.
