Share Wi‑Fi with a QR Code: Guest Access Without Spelling Passwords

How Wi‑Fi QR codes (WIFI:T:...;;) work for meeting rooms and events, security caveats, and generating a downloadable PNG on WoDeTool for free.

What Wi‑Fi QR codes fix

Dictating or handwriting Wi‑Fi passwords fails often — especially long passphrases. A standard Wi‑Fi QR lets phones offer Join Network with one scan.

WoDeTool's Wi‑Fi QR generator supports WPA/WPA2, WEP, and open networks. Enter SSID, password, and hidden-network flags, then export a PNG.

Practical steps

① Match the router's exact SSID (case-sensitive). ② Pick the encryption type (home/office is usually WPA/WPA2). ③ Scan with a second phone before printing. ④ Avoid showing the code on public livestreams where remote viewers can capture it.

For temporary guests, generate a separate guest SSID password with the Password Generator, then encode that QR — safer than sharing the primary network.

Privacy notes

The QR embeds the password in plaintext inside the WIFI: payload. Anyone who can see the code can join. Rotate credentials after events and discard old prints.

Generic QR tools can encode a WIFI: string, but a dedicated generator reduces typos (missing semicolons, bad escaping) that cause join failures.
