How to Set Long Expiry to JWT Token? ›

Here's how you can do it. We're using JwtSecurityTokenHandler to generate JWT tokens. We define a SecurityTokenDescriptor where we set the subject (claims), expiry time, and signing credentials. In the Expires property of SecurityTokenDescriptor , we set the expiry time to 10 years from the current time using DateTime.

In the Expires property of SecurityTokenDescriptor , we set the expiry time to 10 years from the current time using DateTime.

floor(Date. now() / 1000) + (60 * 60), data: 'foobar' }, 'SECRET KEY'); To set the expiry time to an year, you can use value 8760 hours that is 1 year. If you don't provide the expiresIn option or the exp claim, then your JWT will never expire, and it's expiry will be set for maximum age.

When using the Org Authorization Server, the lifetime of the JSON Web Tokens (JWT) is hard-coded to the following values: ID Token: 60 minutes. Access Token: 60 minutes. Refresh Token: 90 days.

This is the time after which the JWT must not be accepted for processing. The "exp" claim is used to prevent JWT token abuse, and to ensure that the JWT is not used for an extended period of time. The "exp" claim is a mandatory claim, and must be included in every JWT.

API Manager uses the Coordinated Universal Time (UTC) time zone for the JWT token expiration and uses the current time on your computer as the baseline time for the token expiration. The token expires on the expiration date you configure and a minute earlier than the time at which you generated the token.

How to check token expiration time? ›

In the console, click on Access Control, and then click on the Users tab. Click on a user. To get information about the user's tokens, including expiration dates, click the Tokens tab.

To refresh the token, your API needs a new endpoint that receives a valid, not expired JWT and returns the same signed JWT with the new expiration field. Then the web application will store the token somewhere.

To handle token expiration gracefully, the authentication function in the client library for each platform (JavaScript, Objetive-C, Java) allows us to set a cancel callback that is triggered when a token expires. The authentication function's success callback will provide authentication info.

While there is no limit to the size of a JWT, in general the larger they are, the more CPU is required to sign and verify them and the more time it takes to transport them.

Best practice

Set the expiration time for refresh tokens in such a way that it is valid for a little longer period than the access tokens. For example, if you set 30 minutes for access token then set (at least) 24 hours for the refresh token.

Access token lifetime

generateAccessToken method to create the token. This method enables you to choose the lifetime of the token, with a maximum lifetime of 12 hours. If you want to extend the token lifetime beyond the default, you must create an organization policy that enables the iam.

Once expired, you need to re-authenticate to obtain a new token. Doing this prevents the same token from being used for an extended period of time, thereby reducing the risk of misappropriation. You can also use refresh tokens to renew new access tokens.

Unfortunately, there is no option to find the expiration time for the refresh token, because it is depending on authorization server and the type of client application, and it is not communicated to the client. In the Microsoft identity platform, the default lifetime for refresh tokens is 90 days.

You can configure token lifetimes in the Azure portal. Go to the Azure portal. In "Azure Active Directory" > "Security" > "Authentication methods" > "Authentication methods blade" > "Token Lifetime Policies". you can configure the lifetime of access tokens, refresh tokens, and ID tokens.
