How do I make a QR code for WiFi?
To make a WiFi QR code, open FixDoks's Wi-Fi QR Code Generator and type your network name and password. The code is built entirely in your browser, so the password never leaves your device. Guests scan it with their phone camera and join instantly, without ever typing the password themselves.

How to use Wi-Fi QR Code Generator
- Type your network name (SSID) exactly as it appears in the Wi-Fi list. Capital letters matter.
- Type the password and choose the security type. Most home and office routers use WPA/WPA2/WPA3.
- Tick Hidden network only if your network does not broadcast its name.
- Download the PNG, print it and stick it near the router, on the reception desk or on the table.
How does a Wi-Fi QR code work?
A Wi-Fi QR code stores your network details in a standard format that phone cameras understand. It looks like WIFI:T:WPA;S:MyHome;P:secret123;;. When someone points their camera at it, the phone reads the network name, security type and password, then offers a single "Join network" button. Nobody has to type or even see the password.
Which phones support it?
The built-in camera app on iPhone (iOS 11 and later) reads Wi-Fi codes. On Android, the camera app or Google Lens reads them on most phones from the last several years, and Android 10 and later also lets you share and scan Wi-Fi codes from the Wi-Fi settings screen. Older phones can use any QR scanner app, which will show the password to copy.
Choosing the right security type
- WPA / WPA2 / WPA3: almost every router made in the last 15 years. Pick this if you are not sure.
- WEP: a very old standard that is no longer secure. Only choose it if your router settings actually say WEP, and consider upgrading.
- No password: an open network, such as a public hotspot with a login page.
If a code does not connect, the most common reason is a small typing difference in the network name or password. Both are case sensitive and spaces count. Copy them from your router's admin page or the sticker on the router to be safe.
Ideas for using it
- Homes: a small card on the fridge for visiting friends and family, so you are not reading out a 16 character password.
- Cafes and restaurants: on table tents or the menu. Customers connect in one scan.
- Hotels, homestays and PG accommodation: in each room or on the welcome sheet.
- Offices and co-working spaces: a separate guest network code at reception, keeping your main network private.
- Events and classrooms: project it on screen at the start of a session.
Keep your network safe
Anyone who scans the code can join your network, so treat a printed code like a written password. For businesses, create a separate guest network on your router and put only that one in the QR code. If you change your Wi-Fi password later, the old code stops working and you need to make a new one. The code is generated in your browser, so your password is never sent to FixDoks.
Printing tips
Choose the 1024 px PNG size, print the code at least 3 cm wide, and add a line of text such as "Scan to join our Wi-Fi" plus the network name for people who prefer to connect manually. Laminate it if it will sit on a cafe table.
