Yes — here are some GitHub Python projects that generate Wi-Fi QR codes you can use to scan with your iPhone (or any phone) to automatically connect to Wi-Fi. These generate standard Wi-Fi QR codes: when scanned by a phone’s camera, it understands the network SSID/password and can join automatically. GitHub<ref>{{cite web|title=GitHub|url=https://github.com/MelonSmasher/WiFiQRGen|publisher=github.com|access-date=2026-01-18}}</ref>

===== #### =====

📦 [GitHub: lakhanmankani/wifi_qrcode_generator](GitHub: lakhanmankani/wifi_qrcode_generator)
A straightforward Python script that generates a Wi-Fi QR code using qrcode and Pillow. You can run it in Python or install as a package. GitHub<ref>{{cite web|title=GitHub|url=https://github.com/lakhanmankani/wifi_qrcode_generator|publisher=github.com|access-date=2026-01-18}}</ref>

Features
* Generates a QR image for an SSID + password.
* Works with standard Wi-Fi formats (WPA, WEP, None).
* Easy to use in your own script.

Basic usage example (from readme):

<syntaxhighlight lang="python">import wifi_qrcode_generator.generator

qr_code = wifi_qrcode_generator.generator.wifi_qrcode(
ssid='MyNetwork',
hidden=False,
authentication_type='WPA',
password='MyPassword123'
)
qr_code.make_image().save('wifi.png')

</syntaxhighlight>

→ Scanning wifi.png with your iPhone camera connects to Wi-Fi. GitHub<ref>{{cite web|title=GitHub|url=https://github.com/lakhanmankani/wifi_qrcode_generator|publisher=github.com|access-date=2026-01-18}}</ref>

====== 📦 [GitHub: vinodvidhole/wifi-qr-code (Notebook)](GitHub: vinodvidhole/wifi-qr-code (Notebook)) ======
A Python notebook that explains and demonstrates generating Wi-Fi QR codes. It’s more of an example/project you can adapt. GitHub<ref>{{cite web|title=GitHub|url=https://github.com/vinodvidhole/wifi-qr-code/blob/main/wifi-qr-code.ipynb|publisher=github.com|access-date=2026-01-18}}</ref>

====== 📦 [GitHub: ustayready/qrwifi](GitHub: ustayready/qrwifi) ======
Another lightweight script that generates a QR PNG from SSID and password, using standard libraries. GitHub<ref>{{cite web|title=GitHub|url=https://github.com/ustayready/qrwifi|publisher=github.com|access-date=2026-01-18}}</ref>

====== If you want a minimal example without a full repo, you can use a gist that just does Wi-Fi QR codes: ======

<syntaxhighlight lang="python">import pyqrcode
import sys

ssid = "YourNetwork"
pwd = "YourPassword"
protocol = "WPA" # valid: WPA, WEP, nopass

data = f"WIFI:S:{ssid};T:{protocol};P:{pwd};;"
qr = pyqrcode.create(data)
qr.png(f"{ssid}_wifi.png", scale=5)

</syntaxhighlight>

This creates a PNG file that phones understand as a Wi-Fi network. Gist<ref>{{cite web|title=Gist|url=https://gist.github.com/GammaGames/7736c7741879e32b5ad2c8b587216445|publisher=gist.github.com|access-date=2026-01-18}}</ref>

===== When you encode a QR with the format <code>WIFI:S:SSID;T:WPA;P:PASSWORD;;</code>, iOS and Android cameras will recognize it and offer to join the Wi-Fi network automatically. Gist<ref>{{cite web|title=Gist|url=https://gist.github.com/GammaGames/7736c7741879e32b5ad2c8b587216445|publisher=gist.github.com|access-date=2026-01-18}}</ref> =====

===== - These scripts don’t configure your router or network — they just encode your credentials into a standard QR format. =====
* You need to provide correct SSID and password in the script.
* When your iPhone scans the generated QR (from screen or print), it will prompt to join the network.

If you want, I can also show you how to build a web interface or command-line tool around these scripts to generate QR codes easily!

===== How to use =====
# Run: python wifi_qr_gui.py
# Enter SSID, choose WPA/WEP/nopass, enter password if needed
# Click Generate QR
# Point your iPhone camera at the QR → it should offer to join the Wi-Fi

If you want, I can also add: dark mode, copy QR to clipboard, auto-detect SSID on your computer, or a “print” layout.
