Wi-Fi QR code guides
Short, specific guides for sharing Wi-Fi with a QR code: on each kind of phone, when a code won't connect, and what's actually inside one.
On your phone
- Wi-Fi QR codes on iPhone
Show your Wi-Fi network's QR code from the iPhone Passwords app, scan a Wi-Fi code with the Camera, and fix the usual iPhone joining problems.
- Share Wi-Fi with a QR code on Android
Share Wi-Fi with a QR code from a Pixel or other Android phone, scan one to join, and see your saved password through the share screen.
- Wi-Fi QR codes on Samsung Galaxy
Find the Wi-Fi QR code button on a Samsung Galaxy, save or share it, and scan a Wi-Fi code with the Samsung Camera.
- Find your saved Wi-Fi password
Find the password of a Wi-Fi network you already use, on iPhone, Mac, Android, Windows or the router itself. No cracking, just your own saved settings.
When something's wrong
- Fix a Wi-Fi QR code that won't connect
Work out whether a Wi-Fi QR code fails to scan, fails to join or joins without internet, then fix it: exact credentials, security type, hidden networks and more.
Before you print
- Use a separate Wi-Fi network for guests
Why a separate guest network belongs behind every printed Wi-Fi sign, what isolation does and doesn't do, and how to rotate the password without chaos.
How it works
- What is inside a Wi-Fi QR code?
What's inside a Wi-Fi QR code: the WIFI: fields, worked escaping examples, hidden networks, and how the ZXing format differs from the WPA3 specification.
- Can an NFC tag share your Wi-Fi?
Can an NFC tag share your Wi-Fi? What a real Wi-Fi tag contains, which phones join from one, what Web NFC can write, and why a QR code is still the safer default.
