Wi-Fi QR code generator
WIFI:T:WPA;S:;P:;;
Encodes your network name, password and security type in the `WIFI:` format that iOS and Android both read natively. Scanning it offers to join the network: no app and no typing.
How to make a wi-fi qr code
The format has escaping rules that catch people out. Semicolons, commas, colons and backslashes inside an SSID or password must be backslash-escaped, or the parser stops at the first one and the code half-works, which is far more confusing than failing outright. That escaping is handled here. Two practical notes: the SSID is case-sensitive and must match exactly, including spaces, and a hidden network needs the hidden flag set or the phone will not find it after decoding. For a café or an office, printing the code and taping it up is genuinely the least friction way to share a long password.
Questions
Yes. iOS since 11 and Android since 10 read them from the camera with no app.
It is escaped for you. Hand-written Wi-Fi QR strings usually break on exactly that.
Yes, including case and spaces. It is matched literally.
No. The data is encoded in the pattern itself, so there is no redirect to go down and no account to lapse. A printed code works for as long as the paper lasts.
No. The code is generated in this page, which is the point, given what it contains.
