No, no, no, the header image for this post isn’t the tip. You know the drill—a friend comes to visit and wants to get on your Wi-Fi network. You’ve written the password down somewhere, but where? Even if you have it handy, it’s a pain for your friend to type in. Since macOS 10.13 High Sierra and iOS 11, Apple’s operating systems can make connecting a lot easier. Have your guest choose your network, and then put their device next to one of your devices that’s awake. As long as you have a card in your Contacts app whose name matches your friend’s My Card in their Contacts, and as long as Bluetooth is enabled on both devices, your device should ask if you want to share the Wi-Fi password with them. Just tap Share Password when prompted and you’re done!
You can even share a network you are not currently connected to, so long as it’s within range. So you can, for example, ask them to connect to your Guest network and as long as your Guest network is known by your device it will be offered. Just make sure you turn off autoconnect for your Guest network on your own device so it doesn’t accidentally switch.
