How to Make a WiFi QR Code (So Guests Join Without Typing a Password)
A WiFi QR code encodes your network's name and password in a specific format that iOS and Android's built-in camera apps both recognize natively — scan it, and the phone offers to join the network directly, no typing required. It's one of the small number of QR content types that isn't just "a link to something" — the code itself carries the actual connection details, and a scanner's camera app handles joining the network on the spot.
Why this is worth setting up
Typing a WiFi password on a phone keyboard is a small but real friction point, especially for long, randomly-generated passwords or for guests who don't want to ask you to spell it out letter by letter. A printed WiFi QR code — on a card by the router, a frame on a café table, a sign in a guest bedroom — removes that entirely. Anyone with a phone camera joins in one scan, and you're not repeating the same password out loud to every new visitor.
This matters most anywhere you have recurring guests who all need the same network: short-term rentals, cafés and coworking spaces offering customer WiFi, waiting rooms, or a guest network at home that visiting family uses a few times a year and never remembers the password for.
What's actually encoded
Under the hood, a WiFi QR code is a small structured text string — not a URL, just plain formatted data listing the network name, the security type (WPA/WPA2, WEP, or none), and the password. The camera app parses that structure and recognizes it as WiFi credentials specifically, rather than treating it as text to display or a link to open. That's also why a WiFi QR code needs the exact network name and password, character for character — a typo in either field produces a code that looks fine but fails to connect, the same way a mistyped password would fail if you'd entered it manually.
Making one
The generator now has a dedicated WiFi tab — enter your network name (SSID) exactly as it appears in your WiFi settings, choose the security type (WPA/WPA2/WPA3 covers the overwhelming majority of routers made in the last decade or more), and enter the password. If your network doesn't broadcast its name — a "hidden SSID" — there's a checkbox for that too, though hidden networks are rare enough now that most people can leave it unchecked.
One thing worth double-checking before you print anything: test the code yourself with your own phone first. Because the whole value of a WiFi QR code depends on getting the SSID and password exactly right, a quick test scan catches a typo before it goes onto fifty printed cards instead of after.
A practical pairing
If you're setting up a WiFi code for guests, consider putting it right next to a vCard contact code or a link to your business page — a small printed card with "Join our WiFi" on one code and "Follow us / contact us" on the other covers the two things a guest most often wants in one glance, without cluttering either code with more than it needs to carry.
The short version
A WiFi QR code lets a scan join a network directly, without anyone typing a password — generated the same static, no-account way as any other code here, just carrying network credentials instead of a link. Get the network name and password exactly right, test it yourself before printing, and it removes one of the more annoying small frictions of hosting guests.
