# Token Generation

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.

#### **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.

#### **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.
