Welcome to the community 🙂
To change your user name and password for your router, Login to the device's Connection Manager at http://192.168.1.1 with the username admin and password admin. Under the WiFi Setting tab you should see the WiFi password. You could also change the WiFi network name (SSID) in the same menu.
