WiFi QR Generator

A WiFi QR code doesn't store a picture of your router settings — it encodes a short structured text string in the format WIFI:T:WPA;S:MyNetwork;P:MyPassword;; where T is the security type (WPA, WEP or nopass for open networks), S is the network name, and P is the password. A hidden field (H:true;) is only added when you mark the network as hidden; for a visible network it's simply left out rather than written as false. Most phone cameras recognize this exact format natively and offer a one-tap "Join Network" prompt instead of just showing text, which is what makes WiFi QR codes so convenient compared to reading a password off a sticker.

This is the standard way to hand out WiFi access at a cafe, office, Airbnb, waiting room or home for guests, since nobody has to type a long, case-sensitive password character by character. It also avoids the awkwardness of saying a password aloud or leaving it written down in plain sight.

Keep in mind that the QR code only reflects the credentials at the moment you generated it — if you change your WiFi password or switch security type later, any previously printed codes stop working and need to be regenerated. Also double-check the security type matches your router exactly; selecting WPA when the network is actually open, or misspelling the network name, produces a code that fails silently on many devices instead of showing a clear error.
