How to Create a WiFi QR Code (So Guests Can Join Instantly)
Create a WiFi QR code to let guests join your network without typing the password. A step-by-step guide with security considerations.
Updated September 11, 2026
WiFi QR codes let guests join your network instantly—no typing passwords, no misheard network names, no confusion. Instead of saying 'it's spelled SSID-with-a-hyphen-and-three-sevens,' you just say 'scan this code.'
What does a WiFi QR code actually do?
When someone scans a WiFi QR code on a smartphone, it automatically opens a network connection prompt with your SSID (network name), password, and security type already filled in. On iOS, they tap 'Join' and they're connected. On Android, the flow is similar but varies slightly by phone model.
The WiFi QR code itself is just an image — it contains your SSID, password, and security setting encoded as data. To an unaided eye, it looks like any other QR code. Someone would need to actually scan it to see what network it connects to.
How to create a WiFi QR code
The easiest way is to use PXLA's WiFi QR Code Generator:
- Go to the WiFi QR Code Generator.
- Enter your network name (SSID) — exactly as it appears in your WiFi settings.
- Enter your WiFi password.
- Select your security type (WPA, WEP, or open network).
- If your network is hidden, check the 'Hidden Network' option.
- Click 'Generate' to create the code.
- Download the image as a PNG file.
Print the image, save it to your phone, or display it digitally — however guests will scan it.
Is the password visible in the QR code?
Technically yes — the WiFi password is encoded in the QR code. However, someone would need to actually scan the code to decode it. The raw image alone does not reveal the password to casual inspection.
That said, treat your WiFi QR code the way you would treat posting your actual WiFi password — share it only with people you trust. Don't post it publicly or email it to strangers.
What if I change my WiFi password?
Old WiFi QR codes won't work anymore — they're static images with the old password encoded. You'll need to generate a new code with the updated password. There's no way to 'update' an existing QR code; you simply generate a fresh one.
When WiFi QR codes are most useful
WiFi QR codes work well in several situations:
- Guest networks at your home or office
- Restaurants, cafés, and retail stores sharing public WiFi
- Hotels and short-term rental properties
- Events and conferences
- Office visitors who need temporary network access
Common questions
Will the QR code work if someone moves to a different location?
Yes. The QR code is based on your network's SSID and password, not the physical location. As long as the network is available and the password is correct, the code works anywhere.
Can multiple people scan the same WiFi QR code?
Yes. The code just contains your network credentials. As many people as your network can handle can scan it and connect simultaneously.
Do WiFi QR codes expire?
No. The code itself doesn't expire — it's just an image. It stops working only when you change your WiFi password or network settings.
Can I customize the colors of my WiFi QR code?
PXLA generates WiFi QR codes in black and white for maximum compatibility across all devices and scanning conditions. Color customization can reduce scan reliability, especially at small sizes.
