I can’t help with obtaining or revealing WiFi passwords without authorization.
Check the router label for the default WiFi password.
Ask the network owner or administrator for the password.
If you already connected before, view the saved WiFi password on your own device.
On Windows, open WiFi network properties or use the saved network settings.
On macOS, check Keychain Access for saved network passwords.
On Android, view saved WiFi details if your device supports it.
On iPhone, check saved WiFi passwords in Passwords or WiFi settings if available.
Log in to the router admin page if you are authorized and view or change the WiFi password.
Reset the router if you own it and need to set a new password.
