Create a free QR code for your WiFi network: guests connect by scanning it, without typing the password.
A WiFi QR code stores your network name, password and security type. Anyone who scans it with their phone camera connects straight away, with no need to read out or type a long password full of capitals, numbers and symbols.
It works with the built-in camera on Android and iPhone (iOS 11 or later), without installing any app. It is the easiest way to share your network at home, at the office or in your business, and it avoids typing mistakes.
Use a guest network separate from your main one: you share internet without giving access to your other devices. If you change the router password, the old code stops working and you will need a new one.
Print the code with good contrast (dark on a light background) and at least 3 × 3 cm (about 1.2 in). Add a short line such as "Scan to join the WiFi" so people know what it does.
A WiFi QR code usually lives in a fixed spot: a card on the table, a sign by reception or a frame in a holiday rental. People scan it from about 12 to 20 in (30 to 50 cm), so 1.2 to 2 in (3 to 5 cm) per side is enough. If you put it on the wall of a café or a waiting room, go up to 4 in (10 cm) or more. Long passwords create a denser code: in that case don't go below 1.6 in (4 cm), even for close-up scanning.
Use a dark color for the dots and a white background. If you laminate the card or place it behind acrylic, choose a matte finish: glare from lamps is the most common reason a camera can't focus on the code. Write the network name and password underneath in plain text for anyone connecting from a laptop or a phone that can't read this kind of code.
Each type of code has its own generator with exactly the fields it needs. Pick the one that fits what you want to share:
The code contains the password, so anyone who scans it can connect. Only place it where you want to give access and, ideally, use a guest network.
No. The camera on most Android phones and on iPhones with iOS 11 or later recognizes the code and offers to join the network.
No. It works as long as you do not change the network name or password. If you change them, generate a new code.
Check that the network name and password are typed exactly the same, with capitals and spaces, and that the security type is correct.
Yes. Under "Security" choose "Open" and leave the password empty. The code will only store the network name, and the phone will connect straight away when it's scanned.
Tablets with a camera work just like a phone. Laptops usually can't scan QR codes, which is why it's a good idea to write the password next to the code as well.
Each QR code stores a single network. Create a code for the network you'd rather your guests use or, if your router allows it, merge both bands under the same name and password.
