## Application settings
In this section you can enable or disable front-end data caching for your Kubernetes environments. When this this option is enabled, Portainer will cache data provided about your Kubernetes cluster in the front-end in order to improve load times when viewing the cluster. This caching can however mean that you may not see fully up-to-date information, and changes made by other users or outside of Portainer may take up to five minutes to update in your session.
## Access tokens
This section allows you to manage your API access tokens. You can see a list of the access tokens that exist for your user as well as add and remove tokens as required.
For more information on access tokens, refer to our [API access documentation](https://docs.portainer.io/api/access#creating-an-access-token).
