Is my WiFi password safe?

Yes. The QR code is generated entirely in your browser. Your WiFi password never leaves your device and is not sent to any server.

Does this work on iPhone?

Yes. iPhone (iOS 11+) and Android (Android 10+) can scan WiFi QR codes natively using the camera app. Older devices may need a QR scanner app.

How do guests connect by scanning the code?

The code holds a WIFI: text string that iOS 11+ and Android 10+ camera apps read natively. When scanned, the phone shows a join-network prompt and connects automatically — no typing the password and no app to install.

Does the QR code store my password in plain text?

Yes. The password is encoded as readable text inside the pattern, so anyone who scans or photographs the code can extract it with a decoder. Treat it like a written password card: display it only in trusted places.

Which security type should I pick?

Choose WPA/WPA2 for almost all modern routers, WPA3 if your router supports it, or None for an open network. Avoid WEP — it is deprecated and easily cracked. The type must match your router actual setting or the connection will fail.

Do I need to reprint the code if I change my Wi-Fi password?

Yes. The password is fixed in the pattern, so a new password means generating and displaying a new code. The old code will simply fail to connect once the password changes.

Can I make a code for a hidden network?

Yes. Tick the hidden-network option so the encoded string flags the SSID as non-broadcast. Without that flag, phones may fail to find and join a hidden network even with the correct name and password.

WiFi QR Code Generator — Share WiFi Password

How to use WiFi QR Code Generator

Generate a QR code that connects guests and customers to your Wi-Fi network instantly — no password typing required. Scan with any modern iPhone or Android camera app and the device joins automatically. Perfect for homes, cafés, offices, Airbnb properties, and events. The password is encoded locally in your browser; it is never transmitted to any server.

Enter your Wi-Fi network name (SSID) exactly as it appears in device settings.
Select the security type: WPA/WPA2 (most networks), WEP (older), or None (open).
Enter the Wi-Fi password (case-sensitive).
Check "Hidden network" if your SSID is not broadcast publicly.
Download the QR code and display it near your router or at your venue.

Your data never leaves your device — 100% private processing.

How Wi-Fi QR codes work

Wi-Fi QR codes encode a WIFI: URI scheme string: WIFI:T:WPA;S:NetworkName;P:password;H:false;; — this is interpreted natively by iOS 11+ and Android 10+ camera apps. When scanned, the OS prompts the user to join the network without showing the password. The QR code contains the plaintext password, so treat it like a physical password card — display it only in trusted locations and regenerate it when you change the Wi-Fi password.

Security considerations

Since the password is encoded in plaintext in the QR code, anyone who scans or photographs the code can extract the password using a QR decoder. For guest networks, this is acceptable and expected behavior. For corporate networks, use a separate SSID for guests with limited network access rather than sharing the main infrastructure Wi-Fi via QR code. Never post a QR code containing a sensitive network password in a public-facing location.

Wi-Fi security protocol comparison
Protocol	Security level	QR code support	Recommendation
WPA3	Highest	Yes (T:WPA3)	Ideal for modern routers
WPA2	High	Yes (T:WPA)	Most common; use if WPA3 unavailable
WEP	Weak (deprecated)	Yes (T:WEP)	Avoid — easily cracked
None (open)	None	Yes (T:nopass)	Public hotspots only

Worked examples

Home WPA2 network

Inputs: SSID HomeWiFi · WPA2 · password

Result: WIFI:T:WPA;S:HomeWiFi;P:****;;

Open guest network

Inputs: SSID CafeGuest · no password

Result: WIFI:T:nopass;S:CafeGuest;;

Glossary

SSID: Service Set Identifier — the human-readable name of a Wi-Fi network, up to 32 characters.
WPA2: Wi-Fi Protected Access 2 — the most common Wi-Fi security protocol, using AES encryption.
Hidden network: A Wi-Fi network that does not broadcast its SSID; devices must know the name to connect.
WIFI URI scheme: A QR code data format (WIFI:T:WPA;S:…;P:…;;) that OS camera apps parse to auto-connect to networks.
