Sharing a WiFi QR code with users is similar to disclosing the WiFi's SSID and password. If you have an open WiFi network and want to give your users free WiFi, a Wi-Fi QR code is perfect for you. However, if you want to share WiFi credentials with a few selected people (like employees), place the WiFi QR code in a secure location. Alternatively, you can skip encoding the password in the WiFi QR code, and users will need to know the password to connect to the network.
