Comment Partager le Wi-Fi Sans Révéler Votre Mot de Passe.
Guide technique complet pour un partage sans fil sécurisé à domicile, sur Airbnb, dans les cafés et en entreprise.
1. 1. Les risques du partage de mot de passe en clair
Handing out plain-text Wi-Fi passwords on notes or speaking them aloud creates permanent security vulnerabilities. Guests' devices stay saved in your router table indefinitely, and passwords can easily be shared with unauthorized third parties.
2. 2. Méthode 1 : QR Code Wi-Fi local dans le navigateur
Generating a Wi-Fi QR Code allows mobile devices to connect automatically without the user ever viewing or typing your plain-text password. Everything runs client-side inside your browser:

3. 3. Méthode 2 : Réseau Invité Isolé (VLAN)
Enable your router's Guest Network (SSID Isolation) feature to keep visitor devices isolated from your private computers, printers, and smart home hubs.
4. 4. Méthode 3 : Partage natif mobile (iOS et Android)
Both Apple (iOS 11+) and Android (Android 10+) offer built-in peer-to-peer Wi-Fi sharing over Bluetooth and Quick Share when devices are in close proximity.
5. 5. Méthode 4 : Connexion par bouton-poussoir WPS
WPS allows client devices to connect by pressing a physical push button on your router within a 2-minute window without revealing passwords.

| Protocol | Security Level | Recommendation |
|---|---|---|
| WPA3 (SAE) | Highest (Forward Secrecy) | Recommended for all modern Wi-Fi 6/7 routers |
| WPA2 (AES) | High (Industry Standard) | Universal compatibility across all smart devices |
| WEP / None | Unsafe / Open | Do not use (Vulnerable to packet cracking) |
