Check the WiFi password printed on the router label
Look in your phone’s WiFi settings for the saved network password (Android: “Share”/QR code; iPhone: Keychain on Mac, or router/admin access)
Use a Windows PC: Settings → Network & Internet → Wi‑Fi → (your network) → View hardware properties → Security → Show characters
Use a Mac: Keychain Access → search your Wi‑Fi name → double-click → check “Show password”
Use another device already connected to the WiFi to view/share the password
Log in to the router’s admin page (usually 192.168.0.1 or 192.168.1.1) and check Wireless/Wi‑Fi settings
If you don’t have access, reset the router to factory settings using the reset button, then set a new WiFi password
Contact the network owner/ISP for the password if it’s managed by a service provider or workplace
