What the code contains
A Wi‑Fi QR code contains the network name, security type, password, and hidden-network setting needed by a compatible phone. Anyone who can scan or photograph the sign can read or use those credentials.
Prefer a guest network
A separate guest network helps keep visitor devices apart from personal or business devices. Use WPA2 or WPA3 where supported and change the guest password when access should end.
Place it deliberately
Treat the sign like a written password. Put it where intended guests can see it, not in a street-facing window or public listing photo.
Qwero privacy
Qwero builds the Wi‑Fi payload in your browser. The network name and password are not sent to Qwero, analytics, Stripe, URLs, or third-party services. Clearing the design removes its local browser copy.
