FAQ — quick answers
Is it safe to share WiFi QR codes?
WiFi QR codes are as safe as sharing your WiFi password verbally or in writing. However, keep these security best practices in mind:
- Use a separate guest network for visitors to keep your main network secure
- Don't post QR codes for private networks publicly online
- Change your WiFi password regularly if QR codes are distributed widely
- Control physical access to printed QR codes in sensitive environments
Can someone hack my network through a QR code?
A WiFi QR code simply encodes your network credentials — it's not a security vulnerability. The QR code itself doesn't create any new security risks beyond sharing your password. Anyone who scans the QR code gains the same access as someone you verbally tell your password. Always use WPA2 or WPA3 encryption and consider a separate guest network for visitors.
Which devices support WiFi QR codes?
Most modern smartphones with built-in QR code scanners support WiFi QR codes:
- iOS (iPhone/iPad): iOS 11 and later (Camera app)
- Android: Android 10+ with Google Camera or third-party QR apps
Note: Older devices may require a third-party QR scanning app with WiFi support.

Printing tips:

- Make sure the QR code is clean and not damaged
- Try regenerating the QR code with higher error correction
