Wi-Fi QR Code Generator

How a Wi-Fi QR code works

The code encodes three things: your network name (SSID), the password, and the security type your router uses. A phone camera reads all three and offers to join the network, so nobody has to find the right SSID in a list or type a long password by hand.

Nothing about the code contacts QRSpike when it is scanned. The credentials live inside the symbol itself, which means it keeps working with no internet connection on the scanner's side and it will still work years from now.

How to make a Wi-Fi QR code

1. Enter your network name exactly as it appears in your phone's Wi-Fi list.
2. Choose the security type — WPA2 for almost every modern router.
3. Enter the password.
4. Style it if you want — the Wi-Fi icon in the center tells guests what the code is for.
5. Download it and test it with a phone that has never joined the network.

Where it earns its keep

• Cafés, bars and waiting rooms. A card on the table beats reciting a password over a noisy room.
• Vacation rentals and guest rooms. Guests get online without messaging you at 11pm.
• Offices with a guest network. Visitors connect without anyone reading the password aloud at reception.
• Trade show booths. One printed card handles every visitor who asks.
• Classrooms and meeting rooms. Put it on the projector's first slide and the whole room is online in a minute.
• Your own home. A framed code by the door saves you looking up the password every time someone visits.

Getting it right

The SSID has to match exactly, capitals included. "CafeGuest" and "cafeguest" are different networks as far as the phone is concerned.

Pick the security type your router actually uses. Most modern networks are WPA2. If you choose the wrong one the phone will try to connect and fail, which looks like a broken code. Choose "No password" only for genuinely open networks.

Test before you print. Scan the downloaded image with a phone that is not already on the network — a phone that has joined before will connect whether or not the code is correct.

Treat the printed code like the password. Anyone who can see it can join. For a guest network that is the whole idea; for your main network, think about where it is displayed.

Change the password, reprint the code. The password is baked into the pattern, so if you rotate your guest password every month, plan on printing a fresh card each time.

Common questions

Do Wi-Fi QR codes work on iPhone and Android?

Yes. The built-in camera app on current iPhones and Android phones recognizes Wi-Fi codes and offers to join the network. No separate scanner app is needed.

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

It is exactly as safe as writing the password on a card, because that is effectively what it is. Use it for a guest network that is kept separate from your own devices, and don't display a code for your main network anywhere public.

Is my password sent to QRSpike?

Only to draw the image. The generator builds the code and returns it; nothing you type is saved, and no account is involved. Once downloaded, the code never contacts us.

Will the code stop working?

Not on its own. It works until you change the network name or password, at which point you make a new one.
