Share Wi-Fi Network Passwords Using QR Codes

/in /by

A neat feature built into iOS, iPadOS, and macOS is that when you are connected to a Wi-Fi network, your devices will offer to share the Wi-Fi password if others near you try to connect to the same network. However, for this feature to work, they must be in your Contacts, and at times, it doesn’t activate as quickly as you’d like. Apple’s new Passwords app on an iPhone, iPad, or Mac provides a manual alternative that may work better. Tap the Wi-Fi collection to see all your remembered networks, select the desired network, and tap Show Network QR Code. When others scan the QR code using their phones, they will instantly join the network.

Social Media: While Apple’s automatic sharing of Wi-Fi passwords feels like magic, it doesn’t work in every situation. For a more reliable manual approach, use the Show Network QR Code feature in the new Passwords app.

Be Careful When Scanning Unknown QR Codes

QR codes, those square, blocky codes you scan with your iPhone’s camera to load a Web page, have become ubiquitous. So much so that we seldom pause before scanning any QR code we see. But if you think about it, that’s the same as clicking random links in emails or texts, which is a terrible idea from a security perspective. “Quishing” (QR code phishing) isn’t commonplace yet, but some sources say there are thousands of cases per month. To avoid falling victim to a quishing scam, only scan QR codes from trusted sources, try to verify what a code will do once scanned, and evaluate the yellow URL preview Safari provides (when using other browsers, all you see is Open in Browser Name). Finally, always install iOS security updates promptly because they often address vulnerabilities that could be exploited with malicious data.
