Should JWT have Username?

Should JWT have Username?

In most cases you don’t need the whole user data and ID will do good in most cases. So I would recommend to store ID (may be some other field too as required) in JWT instead of all the user’s data. However, you should not include any information in the token which the user could abuse within your system.

How do I add a claim to my JWT token?

How to

1. On the JSON web tokens (JWT) settings page, in the Claims section, click Add claim and select Custom for each custom claim that you want to add to your configuration.
2. Specify the mandatory claims by setting their corresponding Required switches to Yes.

What is a claim in JSON Web Token?

Claims constitute the payload part of a JSON web token and represent a set of information exchanged between two parties. The JWT standard distinguishes between reserved claims, public claims, and private claims. In API Gateway context, both public claims and private claims are considered custom claims.

What JWT should contain?

Unserialized JWTs have two main JSON objects in them: the header and the payload . The header object contains information about the JWT itself: the type of token, the signature or encryption algorithm used, the key id, etc. The payload object contains all the relevant information carried by the token.

Are JWT sensitive?

Do not contain any sensitive data in a JWT. These tokens are usually signed to protect against manipulation (not encrypted) so the data in the claims can be easily decoded and read.

What is a token claim?

JSON web tokens (JWTs) claims are pieces of information asserted about a subject. For example, an ID token (which is always a JWT) can contain a claim called name that asserts that the name of the user authenticating is “John Doe”.

When do I need to register a JSON Web Token?

Whenever any new claim name is defined it is necessary that it should be registered in the IANA “JSON Web Token Registry” or it should contain a collision resistant name to avoid collisions. Private Claims: These are custom claims defined and created by two parties in order to exchange information between them.

What can you do with a JWT token?

The JWT token contains claims like expiration date/time that can be used to check its validity.. A JSON Web Token is nothing but a long encoded text string which is made up of three parts separated by a period.

What can be decoded from a JSON token?

The header and payload can be easily decoded (since it’s just base64) to retrieve information contained within the token. The signature can be just used to maintain the integrity of the token and not to secure the contained information.

What happens to a JWT after authentication success?

The service validates username-password. If authentication success it returns an JWT that represents that the user is already authenticated, in other words he is who claim he is. This JWT could contain a payload without sensitive information (don’t store the password here). The user sends another request to a service business with the JWT.
