Create a Wi-Fi QR code for guests to scan and join

Enter the exact SSID, security type, password, and hidden-network setting. AppHelp escapes special characters, builds the standard WIFI payload, masks credentials by default, and exports a QR code or printable guest card without uploading the secret.

Wi-Fi guest access workspace

Encode the exact network credentials, review the secret-bearing payload, and test the final QR code on the devices your guests use.

The QR code contains the network credentials

Anyone who can scan or photograph the code can recover the SSID and password. Prefer a guest network, limit where the card is displayed, and regenerate it after changing credentials.

Quick answer

Enter the exact Wi-Fi network name, choose WPA/WPA2/WPA3 Personal, WEP, or Open, provide the password when required, and mark the network hidden only when its SSID is not broadcast. AppHelp generates a standard WIFI payload such as WIFI:T:WPA;S:Guest WiFi;P:password;H:false;; and exports PNG, SVG, or a guest card locally. Anyone who scans the code can recover the encoded credentials, so use a guest network and control where the code is shared.

How to use

  1. 1. Copy the exact network settingsEnter the SSID exactly as configured, including capitalization and spaces. Choose the security used by the guest network and provide the current password when protected.
  2. 2. Set hidden status accuratelyEnable Hidden network only when the access point does not broadcast the SSID. This flag can affect joining behavior on supported cameras and operating systems.
  3. 3. Review security and payload warningsThe password is masked on screen by default but stored inside the QR code. Reveal or copy the payload only when necessary, and prefer a separate, rotated guest credential.
  4. 4. Export and test representative devicesDownload PNG, SVG, or the guest card, then scan the final screen or print on recent iOS and Android devices. Confirm that the expected network appears and requires no manual corrections.

Examples

WPA guest network

Input
SSID Guest WiFi, password welcome-2026, visible network
Output
WIFI:T:WPA;S:Guest WiFi;P:welcome-2026;H:false;;

Open café network

Input
SSID Cafe Guest, Open security
Output
WIFI:T:nopass;S:Cafe Guest;H:false;;

Open Wi-Fi does not encrypt the wireless link; provide HTTPS and network-isolation protections separately.

SSID with a semicolon

Input
Lobby;Guest
Output
S:Lobby\;Guest;

Reserved payload characters are escaped automatically.

Common use cases

  • Share a rotated guest network at home without spelling a long password
  • Place a controlled Wi-Fi card in an Airbnb, hotel room, office lobby, café, clinic, classroom, or event space
  • Help mobile visitors join a network with punctuation or spaces in its SSID and password
  • Prepare scalable SVG artwork for a sign or a ready-to-print PNG guest card
  • Regenerate access materials after changing the network name, password, security, or hidden setting

Edge cases

  • A Wi-Fi QR code is not password encryption. The credentials are encoded as text and can be recovered by anyone who scans, photographs, or decodes the symbol.
  • Use a dedicated guest network with client isolation and a rotated password instead of exposing a primary home or internal business network.
  • WEP is obsolete and open Wi-Fi does not encrypt the radio link. Prefer WPA2 or WPA3 Personal when client compatibility permits.
  • The common payload uses T:WPA for WPA, WPA2, and WPA3 Personal. WPA3-only and enterprise authentication behavior varies across phones and camera apps.
  • Hidden SSIDs do not provide meaningful security and may require manual joining on devices that ignore the H flag.
  • Changing the SSID, password, security, or hidden status makes an old static QR code stale; generate and replace the displayed code.
  • Captive portals, terms pages, vouchers, enterprise usernames, certificates, and 802.1X settings are outside the simple WIFI payload.
  • Always test the final printed size, contrast, lighting, material, and representative iOS and Android devices.

Features

  • WPA, WPA2, and WPA3 Personal compatibility through the common T:WPA payload
  • WEP, open-network, and hidden-SSID options with security and compatibility guidance
  • Correct escaping for backslashes, semicolons, commas, colons, and quotes in Wi-Fi values
  • Password masking, explicit reveal, and explicit payload-copy controls
  • Live QR version, module count, and UTF-8 payload-size indicators
  • Quiet-zone, export-size, error-correction, and color controls
  • PNG, scalable SVG, and printable guest-card download
  • Browser-local generation with no account or credential upload

Frequently asked questions

What Wi-Fi QR payload does this tool create?
It creates the widely supported WIFI text shape with T for authentication, S for SSID, P for password when needed, and H for hidden status. Reserved characters in the values are escaped.
Does a Wi-Fi QR code hide or encrypt my password?
No. The QR pattern makes the text machine-readable but does not encrypt it. Anyone with access to the symbol can decode and recover the credentials.
Does it work with WPA2 and WPA3?
The common QR convention uses T:WPA for WPA, WPA2, and WPA3 Personal networks. Actual joining support depends on the phone, camera app, and access-point configuration, especially for WPA3-only mode.
Can I generate a QR code for a hidden Wi-Fi network?
Yes. Enable Hidden network to encode H:true. Some devices may still require manual confirmation or may not join hidden networks from a camera scan, so test representative phones.
Why does the QR code scan but not join the network?
Check exact SSID capitalization, password, security type, hidden status, WPA3 compatibility, and escaped special characters. Also confirm that the network is in range and not using enterprise authentication or a captive workflow unsupported by the simple payload.
What happens after I change the Wi-Fi password?
The old static code continues to contain the old credentials. Generate a new code and replace every displayed or shared copy.
Are my network name and password uploaded?
No. Payload construction, QR encoding, preview, copying, and guest-card export happen locally in your browser.
