Comment Créer un Code QR WiFi pour Partager Internet Facilement
Vous avez passé une heure à chercher le mot de passe WiFi griffonné sur un post-it. Ou pire, à l'épeler lettre par lettre pendant que quelqu'un se trompe à chaque caractère. Il doit y avoir une meilleure façon.
Qu'est-ce qu'un Code QR WiFi ?
A WiFi QR Code is a mechanism to share network credentials instantly. It encodes the SSID (Network Name), Password, and Encryption Type (WEP, WPA, WPA2, WPA3) into a pattern.
When an iOS or Android device scans this code, it decrypts the credentials and creates a system prompt: 'Join Network [Name]?'. This bypasses the need for manual typing entirely.
Why Use WiFi QR Codes?
Zero Typos
No more confusing '0' (zero) with 'O' (letter)
Instant Access
Guests connect in 2 seconds flat
Secure Sharing
Keeps your password hidden from casual view
Contactless
Perfect for menus, check-in counters, and Airbnbs
Security Considerations
Is it safe?
Many people worry about exposing their password. Here's why it's safer:
- The password isn't printed in plaintext on the card
- You can easily separate your 'Guest' network from your main LAN
- Physical access is required to scan the code
How to Create a WiFi QR Code
1. Enter Network Details
Type in your exact Network Name (SSID) and Password. Case matters! 'MyWifi' is different from 'mywifi'.
2. Select Encryption
Most modern routers use WPA/WPA2. If you are unsure, this is the safest default. Open networks (cafes) use 'No Encryption'.
3. Hidden Networks?
If your network is hidden (doesn't broadcast SSID), verify the 'Hidden' checkbox.
4. Print & Display
Place the QR code in a frame or stick it to the router itself for easy guest access.

Wrong Encryption Type
If the phone says 'Unable to Join', you likely selected WPA instead of WPA2 or vice versa. Check your router settings.
Hidden SSID
If your network is hidden, standard scans might fail on older Androids unless the 'Hidden' flag is correctly set.
FAQ WiFi
Does this work on iPhone and Android?
Yes, both iOS and Android have native support for scanning WiFi QR codes directly from the camera app.
Can I change the password later?
If you change your router password, you must generate a new QR code. The code stores the password statically.
