WiFi QR generator
A QR with your SSID and password that phone cameras read and connect without typing anything: for guests, clients and prints on the wall.
WPA password needs 8-63 characters.
How it works and security
- The QR follows the standard WIFI: format (with \ ; , : " escaping) that the iOS and Android cameras handle out of the box with a “Connect” button: no extra app.
- The QR contains the password in plain text: anyone with physical access to the printout can join your network. Share only in trusted settings and rotate it if it circulates too much.
- For frequent guests, the right move is a separate guest network on the router and its own QR: the code then never touches your devices.
- WEP is included for legacy device compatibility, but it has been broken for years: if your router only offers WEP, replace it.

“What's the WiFi password?” is the question every bar, hotel, clinic and family home hears daily — and a WiFi QR code ends it: the guest scans, taps “Connect” and is in, without typing long keys. The catch is using the standard WIFI: format with correct escaping (quotes, commas, semicolons and colons in an SSID break badly generated codes). This one is generated to spec, with live validation of the SSID and the key — WPA 8-63 characters, WEP with its historical lengths — hidden network support, and even import of a pasted code to regenerate it. Useful for guest rooms, cafés, clinics or the fridge at home: print the PNG and end the question forever.

Frequently asked questions
Is sharing WiFi with a QR code safe?
The QR holds the password in plain text, just like saying it out loud: anyone seeing the printout can join. The right practice is creating a separate guest network on the router and generating that network's QR, so your main network stays protected.
Does it work with iPhone and Android?
Yes: both native cameras interpret the standard WIFI: format and show the connect button. No extra app is needed and the guest installs nothing.
My key has quotes or semicolons, will it work?
Yes: the tool escapes the special characters (\ ; , : ") per the WIFI: format specification, which is exactly what improvised generators get wrong, making phones reject the code.
