How a Wi-Fi QR code works
The code contains your network details in a standard format that phone cameras understand: network name, security type and password. When scanned, iOS and Android show a “Join network” prompt — one tap and the guest is online.
Because the password is written into the code itself, a Wi-Fi QR code is always static. QRCraft generates it right in your browser — the password is only stored if you choose to save the code to your account.
Keep your network safe
Anyone who can scan the code can join, so share your guest network rather than the one your own devices use. Most routers can create a separate guest network in a couple of minutes.
If you change the Wi-Fi password, generate a new code and replace the printed ones — the old code will stop working because it contains the old password.
