The home WiFi signal is usually emitted by setting up a wireless router. When setting up a wireless router, be sure to pay attention to the security strength of the wireless password. It is best to contain a combination of uppercase and lowercase letters plus numbers, and do not set consecutive numbers, such as "12345678" or other ordered characters, to improve the security of the password and prevent it from being cracked.

When setting up the wireless router, set the security mode of the wifi password to " WPA2-PSK", this mode is more secure than other modes and is not easy to be cracked. Nowadays, relatively new routers generally use this encryption mode by default.
Regularly check the current number of connected devices through the router backend or the router's management software. Generally, the router will recognize the name of the connected device and then compare it with the connected devices in the home. .
If there are extra devices, it is possible that the wifi password has been leaked. In this case, you can prohibit the device from connecting to the Internet, or change the wifi password.
However, after changing the password, all connected devices need to re-verify the connection with the new password.
