Guests on your Wi-Fi, without the password.

Three fields, one code.

Type the network's name exactly as your phone shows it, capital letters and spaces included. Choose its security: WPA, WPA2 or WPA3 for almost every home and office router; WEP only on very old ones; or no password for an open network.

Type the password, and switch on The network is hidden if your router does not show its name. The code is drawn as you type and read back to check it scans; then download it and print it.

On iPhone and Android.

iPhones have joined networks from the camera since iOS 11, and Android phones from their camera or the Wi-Fi settings' own scanner. The code is written as both read it: WIFI:, then the security, the name and the password, with the characters that would confuse a reader (\ ; , " and :) marked so they are read as part of the name or password.

If your router allows WPA3 only, the generator can say so in the code, but some older phones do not know that kind of code. A router that allows both WPA2 and WPA3 is joined by the plain WPA code on every phone.

Who can read it.

The password is in the code as plain text. Anyone who scans it, or has a photo of it, can read it, so put it where only your guests are, and make a guest network for it if your router has one.

The password never leaves your device while you make the code: the generator runs in your browser and works offline.
