An admin WiFi password refers to the password used to access the administrative settings of a WiFi router. This password is set by the network administrator and is used to prevent unauthorized access to the router settings. Access to the admin settings may allow you to modify key network settings such as network name, password, IP address, and also to view network traffic and connected devices. It is important that network administrators ensure that the admin WiFi password is strong and secure to prevent unauthorized access to the network.
