How to Create a WiFi QR Code (Step-by-Step Guide)
A WiFi QR code lets visitors connect to your network instantly by scanning with their phone — no more typing long passwords. Here's exactly how to make one.
How a WiFi QR code works
A WiFi QR code encodes a special text string that phones recognize. When scanned, the phone reads the network name, encryption type, and password, then connects automatically. The format looks like this:
Here T: is the encryption type, S: is the network name (SSID), and P: is the password.
Encryption types explained
- WPA/WPA2/WPA3 — the standard for most home and business networks (use
T:WPA) - WEP — older and less secure, rarely used today
- nopass — for open networks with no password
Most modern routers use WPA2 or WPA3, so T:WPA works for the vast majority of cases.
Step-by-step: make your own
- Find your network name (SSID) and password
- Open our free QR code generator
- Use the WiFi quick-generate box: enter SSID, password, and choose WPA
- Click "Generate WiFi QR" and download the PNG
- Print it or display it on a screen for guests to scan
Where to use WiFi QR codes
WiFi QR codes are ideal for home guests, coffee shops, hotels, Airbnb rentals, and offices. Put one on the wall, the fridge, or a welcome card, and visitors connect in one scan instead of typing a 20-character password.
A quick security note
Only display a WiFi QR code in places you trust. Anyone who can scan it gets your password, so rotate it or use a guest network if you have concerns.
