WiFi QR code generator
Stick it on the fridge or the café wall — guests scan and they're online, no password typing.

A WiFi QR encodes your network name, password and security type in a standard WIFI: string. Most modern phones recognize it from the camera and offer to join instantly. GenHub builds the string for you — just fill in the SSID, password and security.
Tips
- Double-check the SSID spelling and case — it must match exactly.
- Use WPA/WPA2 for home and business networks.
- Export as SVG if you're printing large — it stays sharp at any size.
What's actually inside the code
GenHub builds a standard WIFI: payload — network type, SSID and password fields separated by semicolons, for example WIFI:T:WPA;S:MyNetwork;P:mypassword;; — with special characters like semicolons, commas and backslashes automatically escaped so an unusual SSID or password doesn't break the format.
Choosing a security type
- WPA/WPA2 — the right choice for almost every home and business router today.
- WEP — only for legacy hardware; avoid it if your router supports anything newer.
- Open (no password) — for genuinely open networks; the code skips the password field entirely.
Hidden networks
If your SSID broadcast is off, mark the network as hidden when generating the code — GenHub adds an H:true flag so phones know to actively probe for it instead of just picking it from a visible list.
Where to actually put it
- Cafés and offices — a table tent or a small card near the register beats a paper napkin with the password scrawled on it, and it can't be misread character by character.
- Airbnbs and rentals — leave a printed card by the router; guests join without a single message to the host.
- Home fridge or entryway — for guests, so nobody has to shout a password across the room.
Because the code is static and free, print as many copies as you need — there's no reason to ration them.
A quick sanity check before printing
Scan your own freshly generated code with a second phone before printing anything at volume. It takes a few seconds and catches the one realistic failure mode: a typo in the SSID or password that would otherwise only surface once a guest tries to connect and fails silently.
FAQ
Is my password sent anywhere?
No. The QR is generated entirely in your browser; the network details never leave your device.
Will it work on iPhone and Android?
Yes — both read WiFi QR codes from the native camera app on current versions.
What if I change my WiFi password later?
The printed code encodes the password at generation time, so a changed password means generating and reprinting a new static code — or using a dynamic QR that points to a page with current instructions instead.
Will it work if my SSID has spaces or symbols?
Yes — special characters are automatically escaped in the encoded payload so the code still parses correctly.
Can I make one WiFi code that covers a guest network and a main network?
No — each code encodes one SSID and one password. Generate a separate code for each network you want people to be able to join.
Do I need an account to make a WiFi QR code?
No — WiFi codes are part of the free static QR generator and don't require signing in.
