Wi-Fi QR code generator: Guests join the Wi-Fi without asking

Type your network name and password, and pick the security type if it isn't WPA. You get two codes: Scan to Connect, which phones join from, and Scan to View Wi-Fi Details, which shows the password to copy. Download them, or print the poster or a table tent. Hidden networks work too.

Yes. Make and download both codes without an account. Scan to Connect keeps working for good. Scan to View Wi-Fi Details is a 48-hour preview until you sign in, which is free and keeps it, scan stats included. One Wi-Fi network per account is free.

Not on a phone: Scan to Connect joins your Wi-Fi straight away. For a laptop or another device, Scan to View Wi-Fi Details shows the network name and password large, with a Copy button, so nobody spells anything out across a room.

Yes, in your dashboard. Scan to View Wi-Fi Details points to your page, so it shows the new details straight away. Scan to Connect holds the password itself, so print it again after a change; the dashboard reminds you until you do.

Both. Any phone camera that reads QR codes joins from Scan to Connect, even without mobile data, or opens the details page, with no app to install. The page is tiny, so it loads quickly even on a weak signal.

Point it at your guest network rather than the one your laptops and cameras sit on. Most routers run a second network in a few taps. Anyone close enough to scan the card is already standing in your place.
