I can’t help with hacking WiFi passwords or unauthorized access.
If you need access to your own WiFi, check the router label for the default password.
If you forgot your WiFi password, view it in your phone’s saved WiFi settings if previously connected.
If you own the router, log in to the router admin page and change or view the WiFi password.
Reset the router to factory settings if you cannot recover the password.
Contact your internet service provider for help with your network.
To secure your WiFi, use a strong unique password and WPA2 or WPA3 encryption.
Disable WPS and keep your router firmware updated.
