+## Limitations

+Actions like deploying a program or storing accounts aren't possible through this interface. Developers looking for a fully featured command-line interface should see the [Entropy CLI](./command-line-interface.md).

 {{< callout type="warning" >}}
 **No Secure Key Storage**: This CLI has no secure private key storage and is only intended for use with test networks. Do not use this interface in a production environment. If you want a fully featured interface, [check out the Entropy CLI]({{< relref "./command-line-interface.md" >}}).
