Wi-Fi QR Code Generator
Encode network credentials so a phone offers to join on scan. Both iOS and Android recognise the format natively, which is why this is the standard way to put guest Wi-Fi on a card without reading a password out loud.
This page opens on the Wi-Fi form.
The payload format
The generated string follows a documented convention rather than being an image-only trick, so you can read it back out of any scanned code.
WIFI:T:WPA;S:NetworkName;P:password;H:false;;
T security type - WPA, WEP or nopass
S network name (SSID)
P password, omitted for open networks
H true when the SSID is hiddenThe password is in plain sight
The credentials sit inside the code as readable text. Anyone who photographs the code has the password, and no amount of styling changes that - a printed Wi-Fi code is exactly as sensitive as the password written out longhand.
For a venue, that is usually acceptable and is the point. For a network with access to anything internal, put guests on a separate SSID rather than sharing the main one.
Details that break the scan
- SSIDs are case-sensitive and must match exactly, including spaces.
- Semicolons, commas, colons and backslashes inside a name or password need escaping, which is handled for you here.
- Hidden networks need the hidden flag set, or the phone will not find the network after reading the code.
- Choosing WPA for an open network makes the join fail; use the no-password type.
