# Utilities

- [PingDisplay](https://fish-networking.gitbook.io/docs/fishnet-building-blocks/components/utilities/pingdisplay.md): The PingDisplay can be used to easily display the client's network ping during development.
- [BandwidthDisplay](https://fish-networking.gitbook.io/docs/fishnet-building-blocks/components/utilities/bandwidthdisplay.md): The BandwidthDisplay component is a simple development GUI to show the bandwidth ingress and egress.
- [Authenticator](https://fish-networking.gitbook.io/docs/fishnet-building-blocks/components/utilities/authenticator.md): Authenticators are an additional layer of security. A client must pass the authenticator in order to communicate with the game server.
