It's more convenient and lets you keep a strong password without the hassle of sharing it letter by letter.
The Wi-Fi QR code format
A Wi-Fi QR code encodes a small piece of text in a specific format that phones recognize: WIFI:T:WPA;S:YourNetworkName;P:YourPassword;; — where T is the security type (usually WPA), S is your network name (SSID), and P is the password. Enter that text into the QR generator and it creates a scannable code.
Be exact: the network name and password are case-sensitive and must match precisely, including spaces. When someone scans the finished code, their phone reads these details and offers to join the network automatically.
Use it safely
- Print the code for guests, but treat it like the password itself — anyone who scans it can connect.
- Consider a separate guest network so visitors don't get access to your main devices.
- Don't post your home Wi-Fi code publicly online.
- Update the code if you change your password.
- For a café or office, a guest network with a QR code is ideal.
