How to Make a Wi-Fi QR Code
Quick answer: open a Wi-Fi QR code generator, enter your network name (SSID) and password, choose your security type (usually WPA), and download the PNG. Anyone who scans it with their phone camera gets a one-tap “Join Network” prompt — no typing.
Step 1: Find your exact network name and password
Your network name (SSID) must match exactly, including capitalization and spaces — Sharma Home and sharma home are different networks to a phone. The name and password are usually printed on a sticker on your router; the password may be labelled WPA key, wireless key, or passphrase.
Step 2 (recommended): Set a strong password first
Since guests will never type it again, this is the perfect moment to upgrade a weak Wi-Fi password. Generate a random 20-character password with our Wi-Fi password generator, update it in your router settings, and encode the new one. Convenience for guests, stronger security for you.
Step 3: Generate the code
In the QR code generator, select Wi-Fi network as the type, enter your SSID and password, and pick your security type — WPA covers WPA, WPA2, and WPA3, which is nearly every modern router. Click Generate. Because the tool runs entirely in your browser, your Wi-Fi credentials never leave your device.
Step 4: Download and print
Download the PNG at 1024 pixels for printing. Size guideline: minimum 2 × 2 cm for arm's-length scanning (a framed card on a desk or fridge), and scanning distance ÷ 10 for anything mounted on a wall — a code scanned from 1 meter should be at least 10 cm wide. Leave white space around the code; patterned backgrounds hurt scanning.
Step 5: Test before you display it
Forget your own network on your phone temporarily, then scan the printed code with the camera app. If the Join prompt appears and connects, you're done. If nothing happens, the usual culprits are a typo in the SSID, the wrong security type, or the code printed too small.
Where Wi-Fi QR codes work brilliantly
Homes with frequent guests, cafes and restaurants (table tents or menu corners), guest houses and homestays, offices with a visitor network, and events. For businesses, pairing the Wi-Fi code with your Google review link on the same card turns a routine connection into a review opportunity.
Frequently asked questions
How do guests scan a Wi-Fi QR code?
With the regular camera app. iPhone (iOS 11+) and Android (10+ natively) show a Join Network prompt — one tap connects, no typing.
Is it safe to put my Wi-Fi password in a QR code?
The password is extractable from the printed pattern, so treat the print like a written-down password: display it indoors, not in windows or public photos. A client-side generator means the password never touches a server.
Does the code stop working if I change my password?
The old code encodes the old password, so generate and print a new one after any change. The code itself never expires.
Can I make a code for an open network?
Yes — choose the no-password option and leave the password blank. Scanning connects directly, though open networks aren't encrypted.
