The router admin password is the one that opens the router settings page, and it is separate from the Wi-Fi password. If it is lost and the default no longer works, a factory reset is the only way back in, and it wipes every custom setting.
If the reset button does nothing, check the maker's support site for the exact reset procedure for the model, since the button timing and the reset method vary. Some routers need the button held while the power is plugged back in, and some have a reset option in the app instead of a physical button. If the router was supplied by the internet provider, the provider's app or support pages may manage it, and the provider can replace it if the reset fails. If the label is worn off or missing, the maker's support site lists the default login by model number.
Change the default admin password during setup, and store it in a password manager along with the Wi-Fi password and the admin page address. Keep a note of the router model and the default login with the password, so a future reset is a five minute job instead of a search. Never leave the admin password at the factory default, since anyone on the network can look it up.
Is the router admin password the same as the Wi-Fi password? No. The admin password opens the router settings page, while the Wi-Fi password connects devices to the wireless network. They are set separately and can be different.
Will a factory reset change my internet service? No. A factory reset only clears the router's own settings. The internet service itself is unaffected, but the Wi-Fi name and password return to the factory defaults, so every device has to be set up again.
How long do I hold the router reset button? About 10 seconds, until the lights change or the router restarts. Check the maker's guide for the exact timing on the model, since it varies.
