Local Processing Only

How to Use

Select the Security Type (WPA/WPA2/WPA3, etc.).

Enter the Password (not sent to any server).

Check "Hidden Network" if applicable.

Download or print the generated QR code.

Overview

No more dictating long Wi-Fi passwords or asking guests to type them in. With this tool, you can create a QR code containing SSID and password information, allowing instant Wi-Fi connection just by scanning with a smartphone camera. Perfect for hospitality in shops, offices, and home parties.

Capabilities

Encodes SSID, auth type, and password into a single QR code for error-free Wi-Fi connection.

Use Cases

Most effective for guest Wi-Fi onboarding in retail, events, and office spaces.

How It Works

Generates payloads under the `WIFI:` schema so scanner OS can process them as network join candidates.

Cautions

Auth compatibility differs on legacy devices; validate on representative hardware before rollout.

Technical and Practical Benefits

Support for WPA3 (SAE) and OWE

This tool supports the latest security standards WPA3 (SAE) and OWE (Enhanced Open). It offers higher resistance to dictionary attacks compared to WPA2, enabling safer Wi-Fi provision in public spaces.

OS-Specific Behavior

On iOS, a popup asks to join the network, allowing one-tap connection. Android (10+) also connects smoothly via Easy Connect. Verifying the SSID upon scanning prevents connection to unintended networks.

Stealth SSID Risks

When using "Hidden Network (H:true)", some Android devices may struggle to connect. While this tool configures parameters correctly, disabling stealth mode for guest Wi-Fi is often recommended to avoid issues.

Technical Specifications

                Schema: `WIFI:T:<Security>;S:<SSID>;P:<Password>;H:<Hidden>;;`
Supported Security: WEP, WPA, WPA2-EAP, WPA3-Personal (SAE), OWE (Enhanced Open), nopass (Open).
Processing: Runs entirely in your browser (no server upload).

FAQ

Is my SSID/password sent to a server?

No. QR creation runs in your browser, and your input is not sent to an external server.

Does the QR code expire?

No. But if you change the SSID or password on your router, you will need to generate a new QR code.

Which security type should I choose (WPA/WEP/None)?

If you are unsure, choose WPA. Use None (Open) for password-less networks. WEP is an older scheme and is generally not recommended.

Can I create a QR code for an open Wi‑Fi network?

Yes. Select None (Open) and leave the password empty.

Should I enable Hidden Network?

Only if your Wi‑Fi uses a hidden SSID. Some devices may have trouble connecting, so leaving it off is usually best for guest Wi‑Fi.

Is the connection flow the same on iPhone and Android?

Mostly, but prompts vary by device and OS version. Do a quick scan test on the devices you expect people to use.

Any tips for printing and posting the code?

Keep a clear white margin (quiet zone) and print it large enough. Reflective materials and dark backgrounds can reduce scan reliability.

Is it safe to post a Wi‑Fi QR code publicly?

Anyone who can scan it may connect. Use a guest SSID/password and rotate it if needed.
