# Token Generation
You can create a JWT (JSON Web Token) for authentication and session management. This allows you to configure which data should be included in the token.
In the **Token Generation** section, you can configure the following:
#### **Token Secret Key**
Specify the secret key to use for generating the token. This key is essential for validating the token and ensuring a more secure system. Always select keys from the **Secrets** section.
Configure Token Secret Key
#### **Expiry Time**
Set the expiry time for the token, indicating how long it will remain valid. After this time, the token becomes invalid. You can choose from a dropdown list of available values.
Configure Expiry Time
#### **Token Data**
Define the data that should be included in the token. You can add key-value pairs, where the key represents the name of the value. For dynamic values, use the dynamic data source model by clicking the plus (+) icon.
