Hello, I'd like to assure you that there is indeed a powerline network name for our devices. When two devices are successfully paired, they generate a random and confidential powerline network name, which ensures a high level of security. If you prefer not to use the pair button, you can manually set the same powerline network name for different powerline adapters to pair them.

Here is how you can set a new powerline network name using the tpPLC Utility: How to set a new powerline network name using tpPLC Utility

Please note that there are three methods available to pair TP-Link powerline adapters. In addition to using the pair button or manually setting the same powerline network name, you can also add an extra powerline device by using the powerline key: How to add an extra Powerline adapter to the existing Powerline network by adding the powerline key on tpPLC Utility

Regardless of the pairing method you choose, it is important to have either the powerline network name, powerline key, or access to the pair button. Additionally, the powerline adapters need to be plugged into the same circuit for proper functionality. So please don't worry about the security.
