A Wi‑Fi QR code encodes your network's SSID, encryption type, and password into a scannable 2D barcode using the standardized WIFI: URI format. When scanned with a smartphone camera or QR reader, the device automatically connects to the network — no manual typing required. It's perfect for guest networks, cafes, hotels, and home sharing. Both iOS (since iOS 11) and Android (since Android 10) natively support scanning Wi‑Fi QR codes directly from the camera app.

WPA3 (Wi‑Fi Protected Access 3) is the latest Wi‑Fi security protocol, introduced in 2018. Its key advantages over WPA2 include: SAE (Simultaneous Authentication of Equals) which protects against offline dictionary attacks; forward secrecy ensuring past sessions remain secure even if the password is compromised; 192-bit encryption for enterprise networks; and easier secure setup for IoT devices via Wi‑Fi Easy Connect. WPA3 is backward-compatible with WPA2 devices through transition mode. If your router supports WPA3, it's strongly recommended.

A hidden network does not broadcast its SSID (network name) in beacon frames, meaning it won't appear in nearby devices' Wi‑Fi lists. While it adds a minor layer of obscurity, it's not a real security measure — determined attackers can still discover hidden SSIDs using packet sniffers. Hidden networks can also cause connectivity issues with some IoT devices and older hardware. However, they remain useful for reducing casual connection attempts and keeping your network "invisible" to neighbors. Our generator properly encodes the H:true parameter so hidden-network QR codes work correctly.

iPhone (iOS 11+): Open the built-in Camera app and point it at the QR code. A yellow notification banner will appear at the top — tap it to join the network instantly. Alternatively, use the Code Scanner in Control Center (iOS 14+).

Android (10+): Open the Camera app and point at the QR code. Tap the Wi‑Fi notification that appears. On Samsung devices, you can also use Settings → Connections → Wi‑Fi → QR Code scanner. Most Android skins (Pixel, OnePlus, Xiaomi) now have native QR Wi‑Fi scanning built into the camera.

Sharing a Wi‑Fi QR code is as safe as sharing your password verbally — anyone who scans it can connect. Our generator processes everything locally in your browser; no data is ever uploaded, stored, or transmitted. For security: only share QR codes with trusted individuals; use a guest network with client isolation for visitors; rotate passwords periodically; and never post QR codes publicly online. All QR generation happens 100% client-side — your credentials never leave your device.

A Wi‑Fi QR code contains a simple text string in the format: WIFI:T:<encryption>;S:<SSID>;P:<password>;H:<hidden>;;. It includes: the encryption type (WPA3, WPA2, WPA, WEP, or nopass), the network name (SSID), the password (if applicable), and optionally a hidden flag (H:true). No personal information, device identifiers, or tracking data is included. The QR code is a purely static encoding of connection credentials — just like typing them manually, but faster.

Absolutely! Use the Print button for a printer-optimized output, or Download PNG to get a high-resolution image (256×256px with H-level error correction) suitable for: guest house signs, Airbnb welcome cards, café table tents, office bulletin boards, or laminated cards. For best results, print at least 2×2 inches (5×5 cm) and ensure good contrast. The QR code uses error correction level H (30% recoverable), so it remains scannable even with minor damage or wear.

WPA3-SAE (Simultaneous Authentication of Equals) — also called WPA3-Personal — is designed for home and small business use. It uses a password-based key exchange that's resistant to offline brute-force attacks, replacing WPA2's PSK with a more secure handshake.

WPA3-Enterprise uses 802.1X authentication with RADIUS servers and supports 192-bit encryption for government/financial-grade security. It requires a centralized authentication server. This tool generates QR codes for WPA3-SAE (Personal), which is what most modern home routers support.

Common issues and fixes:
• SSID contains special characters (like ; : , \) — our tool automatically escapes these, but double-check the connection string.
• Password too short/long — WPA2/WPA3 require 8–63 characters.
• Hidden network not connecting — ensure the device has "Connect to hidden network" enabled and the exact SSID matches (case-sensitive).
• Scanner can't read QR — increase screen brightness, clean camera lens, or download the PNG and print at a larger size.
• WPA3 not supported — older devices may not support WPA3; use WPA2 for broader compatibility.

No — absolutely nothing. All QR code generation happens entirely within your browser using client-side JavaScript. Your SSID, password, and network configuration never leave your device. No analytics, no tracking, no data collection. This is a core design principle of our tool. You can even disconnect from the internet after loading the page and the generator will continue working perfectly offline.
