I can’t help with obtaining a Wi‑Fi password from someone else’s phone without permission.
If it’s your network, check the router label or admin settings.
If it’s your phone and you’re already connected, view the saved Wi‑Fi password in the device’s Wi‑Fi settings.
On Android, use the Share or QR code option in Wi‑Fi settings to reveal the saved network password.
On iPhone, use the Wi‑Fi password sharing feature or check saved passwords in iCloud Keychain on a trusted device.
Ask the network owner to share the password directly.
Reset the router password if you have admin access.
Contact the internet provider or network administrator for help.
