Share your Wi-Fi with a QR code
"What's the Wi-Fi password?" is the most-asked question in every home, cafe, rental, and waiting room. A Wi-Fi QR code answers it permanently: guests point their camera at the code, tap the prompt, and they're on the network. No spelling out "capital B, underscore, the number four", no password taped to the router.
How it works
A Wi-Fi QR code packs your network name, password, and security type into a standard format that both iPhone and Android cameras have understood natively for years. Scanning one shows a "Join network" prompt; one tap and the phone connects and remembers the network. Nothing to install, nothing to type.
Step 1: enter the network details
Open the Wi-Fi QR code generator and fill in three fields: the network name (SSID) exactly as it appears in your Wi-Fi list, the password, and the security type. Almost every modern network is WPA / WPA2, which is Reticle's default; WEP and open networks with no password are there if you need them. Running a network that doesn't broadcast its name? Tick hidden network and phones will search for it anyway.
Step 2: make it look inviting
A bare black-and-white square works, but a designed one gets scanned. Pick a color that fits the room, round the modules, or drop your logo in the middle (Reticle automatically raises error correction to compensate). The biggest win is a "Scan me" frame: add a caption like "JOIN OUR WI-FI" and the code explains itself from across the counter. Frames and captions are built in; no image editor needed.
Step 3: test it before you print it
Hit Test scan under the preview. Reticle decodes the exact image you're about to export, on your device, and confirms it reads back perfectly, so typos in the password surface now rather than after your guests arrive. For codes that will live on a fridge, a laminated card, or a picture frame, consider raising error correction to Q or H in Appearance: it lets the code survive glare, smudges, and the occasional coffee splash.
Step 4: print it where guests need it
Use the Print button for a clean, code-only page straight from the browser, or download a PNG or SVG to drop into a nicer card design. Print at least 2 cm (about an inch) square, keep some empty margin around the code, and place it at eye level where guests naturally look: the entry table, the coffee station, the guest room nightstand, the bottom of the menu.
A note on security
The code contains your actual password, and phones can reveal it after scanning. That's the point, but it means the printed code deserves the same care as the password itself. The clean setup is a separate guest network: guests get internet, your own devices stay on the main network, and rotating the guest password later only means reprinting one card. And because Reticle builds the code entirely in your browser, your credentials are never uploaded anywhere in the first place.
Frequently asked questions
Do Wi-Fi QR codes work on both iPhone and Android?
Yes. Both platforms have understood Wi-Fi QR codes in the built-in camera for years; scanning shows a prompt to join the network. Very old phones may need a QR scanner app, but any phone from the last several years handles it natively.
Is my Wi-Fi password uploaded when I make the code?
No. Reticle generates the code entirely in your browser; the network name and password never leave your device. There is no account required either.
Can anyone who sees the code get my password?
Yes, the password is stored inside the code, and some phones display it after scanning. Treat the printed code like the password itself: post it where only guests can see it, and prefer a separate guest network.
What happens if I change my Wi-Fi password?
The code stops working, since the old password is baked into the image. Generate a fresh code and reprint it. Wi-Fi codes are static by nature, so a redirect service would not help here.
Does it work for hidden networks?
Yes. Tick the hidden network box and the code tells the phone to look for your network even though it is not broadcasting its name.
