Prepare a guest connection, not a hidden password

This tool builds a WPA-style network payload. The network name and password are readable inside it. It does not configure your router or support enterprise certificates, usernames, or captive-portal login.

Create and check it

  1. Use the exact guest network name, including spaces and capitalization.
  2. Enter the password normally. Special punctuation is escaped by the generator; do not escape it yourself.
  3. Download and test with a device that is not already connected. Confirm internet access as well as joining the network.

WIFI:T:WPA;S:CafeGuest;P:sample-password;;

Anyone with the image can recover the password. Downloads also store it in this browser’s history. Clear history on a shared computer and replace printed cards when the password changes.

Troubleshooting this QR type

Scanning works but joining fails
Compare the SSID and password with the router, then check network compatibility.
The phone joins without internet
Check the network itself and any portal; this is not an image decoding problem.
