Does a Wi-Fi QR code expire?

No. The network details are stored in the code itself, so it works as long as your network name and password stay the same.

Is it safe to share my Wi-Fi with a QR code?

It's as safe as telling someone the password — anyone who scans it can connect and could read the password from the code. Use a guest network for visitors where possible.

About this tool

The QR code contains your network name, password and security type in the standard Wi-Fi format that iPhone (iOS 11+) and Android camera apps recognise. Scanning shows a "Join network" prompt, so guests connect in seconds. Special characters such as ; , : and " in names and passwords are escaped correctly so the code doesn't break.

The code is static: the network details are stored inside it, not on a server, so it never expires and keeps working without this website. If you change your Wi-Fi password, make a new code. The QR code is generated in your browser — your Wi-Fi password isn't sent anywhere.

Anyone who can see the QR code can join your network, just as if they knew the password. For businesses, a separate guest network keeps visitors away from your private devices.

Frequently asked questions

Yes. On iPhone (iOS 11 or later), open the Camera app and point it at the code, then tap the Wi-Fi notification to join. Android phones do the same through the camera or Google Lens.
