Understanding WiFi QR Codes

        
WiFi QR codes encode network credentials using the WIFI: URI scheme, a standard format recognized by Android 10+, iOS 11+, and most modern QR scanning applications. When decoded, the format looks like:

        
WIFI:T:WPA2;S:MyNetwork;P:MyPassword;H:false;;

        
Where T is the security type (WPA, WPA2, WEP, or nopass), S is the SSID (network name), P is the password, and H indicates whether the network is hidden.

        
Security Types Supported

        
    
          
  • WPA/WPA2 — Most common; uses a pre-shared key (password)
    • 
          
  • WEP — Older, deprecated standard; considered insecure
    • 
          
  • nopass — Open network with no password required
    • 
          
  • WPA3 — Newer standard; encoded similarly to WPA2
    • 
        

        
Use Cases

        
    
          
  • Restaurants and cafés displaying guest WiFi on menus or signs
    • 
          
  • Hotels providing room WiFi via printed QR codes
    • 
          
  • Offices with visitor network QR codes at reception
    • 
          
  • Recovering your own WiFi password from a generated QR code
    • 
          
  • Sharing WiFi credentials with guests without saying the password aloud
    • 
        

      

      

        
WiFi QR Code Security Risks

        
WiFi QR codes present unique security considerations that users should be aware of. Because the password is encoded directly in the QR pattern, anyone who can photograph or copy the QR code has immediate access to the password — there is no additional authentication step.

        
Risks to Be Aware Of

        
    
          
  • Physical access: Posted QR codes in public-facing locations can be photographed and the password extracted by anyone, not just legitimate guests
    • 
          
  • QR substitution attacks: Malicious stickers can be placed over legitimate QR codes in hotels or cafés, redirecting to a different network designed to intercept traffic
    • 
          
  • Permanent credentials: If a WiFi QR code is generated with a permanent password, the network remains exposed until the password is changed and a new QR code generated
    • 
        

        
Best Practices

        
    
          
  • Use a separate guest network for QR-shared credentials — never share your primary network password via QR
    • 
          
  • Rotate guest WiFi passwords and QR codes regularly (monthly for public venues)
    • 
          
  • Inspect QR codes in public places for signs of tampering or overlaid stickers
    • 
          
  • Use our decoder to verify that a WiFi QR code contains the correct credentials before distributing it

FAQ
WiFi QR Decoder FAQ

    

      
Can I see the WiFi password from a QR code?
Yes. WiFi QR codes store the password in plain text in the WIFI: format. Our decoder will display the full SSID, password, and security type when you decode a WiFi QR code.

      
Why does decoding show "WIFI:T:WPA2;S:..." instead of the password?
Our decoder automatically parses this format and displays it in a human-readable layout with labeled fields. The raw WIFI: string is also available if you need to copy it as-is.

      
Is the decoded WiFi password saved anywhere?
No. All decoding is done in your browser. Nothing is uploaded to any server. The decoded credentials exist only in your browser's memory for the current session.

      
Can I automatically connect to WiFi using this decoder?
Web browsers don't have permission to directly modify WiFi settings for security reasons. You'll need to copy the credentials and enter them manually in your device's WiFi settings, or scan the QR code directly with your device's camera app.
