Free WiFi QR code generator
Let guests scan to connect. No password typing
A WiFi QR code generator turns your network credentials into a single scannable code. Instead of reading a long, case-sensitive password out loud or writing it on a sticky note, you print one clean code. Guests open their phone camera, point it at the code, and tap a prompt to join your network instantly. QRHub’s WiFi tool is 100% free, requires no account, and is ready to print or display the moment you generate it.
Whether you run a busy cafe, a boutique hotel, a coworking space, a clinic, or simply want an easier way to share WiFi at home, a scan-to-connect WiFi code removes friction for everyone. It works natively on iPhone and Android, supports every common encryption standard, and takes under thirty seconds to create. No app downloads, no watermark, and no limit on how many codes you can generate.
What is a WiFi QR code and how does it work?
A WiFi QR code encodes three pieces of information in a standardized format that phones recognize automatically: the network name (SSID), the password, and the encryption type. Under the hood, the data is stored as a short text string beginning with WIFI: . But you never have to write or understand that syntax. QRHub builds it for you from the simple form above.
When a guest scans the code with their camera, the operating system reads the encoded credentials and shows a one-tap prompt to join the network. There is no browser step, no captive portal to fumble through, and no chance of mistyping a password. This is why WiFi QR codes have become the standard way to share access in hospitality, retail, events, and modern offices. They turn a common point of friction into a two-second interaction.
Is sharing WiFi by QR code secure?
For guest and public networks, a WiFi QR code is a convenient and low-risk way to share access. The password is encoded directly into the image, so anyone who scans the printed code can join. Which is exactly what you want in a cafe, hotel lobby, or event hall. To keep your core systems protected, the best practice is to create a dedicated guest network that is isolated from your point-of-sale terminals, back-office computers, and smart devices.
Because QRHub generates everything in your browser, you can create, customize, and download a WiFi code without creating an account. When you rotate your password on a schedule. A smart habit for any public network. Just generate a fresh code and swap out the printed version. It is a one-time reprint of a single sticker rather than a full redesign of your signage.
