Wi-Fi QR Code Generator
A Wi-Fi QR code lets anyone join your network by scanning it — no typing the password. Enter your network name, password and security type below, and Qrogo builds a free, downloadable code right in your browser. It works with WPA/WPA2, WEP and open networks, on both iPhone and Android.

The short answer
A Wi-Fi QR code encodes your network name, password, and security type into the pattern, so anyone who scans it gets a one-tap prompt to join instead of typing a password. Enter those three details and Qrogo builds the code in your browser — free, no account, and nothing sent to a server. It works with WPA/WPA2, WEP, and open networks, and joins from the stock camera on iPhone from iOS 11 and most Android from version 10.
Two things to get right. Match the security type to your router exactly, since a mismatch fails silently, and copy-paste the SSID rather than retyping it, because it is case-sensitive. Print it at least 2 × 2 cm, dark on light, with clear space around it. The code is static and permanent, so it works offline — but because the password is baked in, changing the password means generating a fresh code.
Already connected to the network and just want its code? Android can show it for you — and here's the iPhone route.
How to make a Wi-Fi QR code
- Enter your network name (SSID) exactly as it appears on devices — it's case-sensitive.
- Type the password and pick the matching security type (WPA/WPA2 for almost all routers).
- Download the PNG for print or the SVG for sharp scaling on signage.
- Test it with your own phone before printing a batch — open the camera and confirm the "Join network" prompt appears.
Where a Wi-Fi QR code actually helps
The codes earn their keep anywhere guests repeatedly ask for the password. In practice the highest-value spots are:
- Cafés and restaurants — a small table tent stops staff reciting the password all day.
- Short-term rentals and hotels — put it in the welcome book or on the fridge; guests connect in seconds.
- Offices and meeting rooms — a guest-network code on the wall keeps visitors off your main network.
- Events and pop-ups — print it once on signage instead of repeating it to every attendee.
WPA/WPA2 vs WEP vs open networks
The security type must match your router or the join will silently fail. WPA/WPA2 covers essentially every router made in the last decade and is the right default. WEP is obsolete and insecure — only use it if you're stuck with very old hardware. None is for genuinely open networks with no password.
Why a Wi-Fi QR code won't scan (and how to fix it)
- Wrong security type — the most common cause. Double-check WPA vs WEP.
- SSID typo or wrong case — "CafeWifi" and "cafewifi" are different networks.
- Too small or low contrast when printed — keep the printed code at least 2 × 2 cm and high-contrast.
- Special characters in the password — Qrogo escapes these automatically, but a manual code may break on

Frequently asked questions
How does a Wi-Fi QR code work?
The code stores your network name (SSID), password and security type in a standard format. When a phone camera reads it, the OS recognises the Wi-Fi format and offers a one-tap prompt to join the network — no password typing.
Is it safe to share a Wi-Fi QR code?
Anyone who can see and scan the code can join the network, so treat it like the written password: display it where you'd already share access (a café wall, a guest room) and keep it off the public internet. Qrogo builds the code in your browser, so the password isn't sent to a server.
Does a Wi-Fi QR code work on iPhone and Android?
Yes. Modern iOS (11+) and Android (10+) cameras recognise Wi-Fi QR codes natively. Older phones may need a dedicated QR scanner app.
Which security type should I choose?
Pick WPA/WPA2 for almost all modern routers. Choose WEP only for old legacy hardware, and 'None' for open networks with no password.
Can I change the password later without a new code?
A standard Wi-Fi QR code is static — it encodes the password directly, so changing the password means generating a new code. If you change credentials often, link a short URL to a hosted instructions page instead.
