Free Wi-Fi QR code generator

Share your Wi-Fi with a scan

Enter your network name and password above and download a free Wi-Fi QR code: guests point their camera at it and tap Join, with no password to read out or type. It works on iPhone (iOS 11+) and Android (10+) with no app, and your details are encoded entirely in your browser, never uploaded to a server.

To create yours:

  1. 1

    Enter your network name (SSID)

    Exactly as it appears, including capitals.

  2. 2

    Choose your security type

    WPA/WPA2/WPA3 for almost every network.

  3. 3

    Type your password

    Special characters are escaped automatically.

  4. 4

Hidden network?

Turn on the Hidden toggle so phones actively search for your network by name.

What the code actually stores

This is not a link to your network. It is a single text string in the standard Wi-Fi QR format: something like WIFI:T:WPA;S:CafeGuest;P:s3cret!;;. T is the security type, S the network name and P the password, filled in from what you type above. A semicolon, comma, colon, backslash or quote mark inside your SSID or password is escaped automatically with a backslash, so the phone reading the code cannot mistake it for one of the separators. Switch on Hidden network and the code adds H:true, which tells the phone to actively probe for a network that isn’t broadcasting its name, rather than wait to spot it in a scan.

Where to put a Wi-Fi QR code

Put it on a table tent, a reception sign or inside a kitchen cupboard. Matte lamination beats gloss here: a shiny surface throws glare back at the camera and stops it focusing, especially under downlights. Leave a plain margin around the code rather than trimming close to the pattern. That margin (the “quiet zone”) is how a scanner finds the code’s edges in the first place. For the full walkthrough (WPA3, special characters and troubleshooting) read how to make a Wi-Fi QR code.

Anyone who can photograph it can join

There is no encryption on top of this. The password sits in the code as plain, readable text: exactly what a scanning phone decodes and uses to connect. Anyone who photographs a printed code, not just scans it, can read the password straight out of it with any QR reader, including someone standing well outside your premises with a long lens. Keep public codes on a separate guest network rather than the one your own devices use, and treat a printed code the way you’d treat a password written on a whiteboard: once it’s up, assume it’s been read. This format also has no room for enterprise Wi-Fi that authenticates each person with their own login (802.1X, common on office and university networks), only a single shared password, so those networks still need manual set-up.
