What gets encoded
Most phones understand: WIFI:T:<type>;S:<ssid>;P:<password>;;
- T — WPA, WEP, or nopass
- S — network name (SSID)
- P — password (empty if open)
Safety tips
- Prefer a dedicated guest network with its own password.
- Don’t post a primary WiFi QR on public social media.
- Regenerate if you rotate the password.
