In iOS 11, there’s a handy new feature that’s designed to let you quickly share your Wi-Fi password with a friend, and, if you’re at a friend’s house, to get the Wi-Fi password with just a tap.

The only prerequisite for this feature, aside from iOS 11, is that you and your friend need to have each other listed as contacts in the Contacts app. Here’s how it works:
When a friend is at your house, have them open up the Settings app.
Tap on Wi-Fi, and let the iPhone look for available networks.
Have your friend tap on the name of your Wi-fi network.
From there, you’ll get a popup on your own iPhone that asks you if you want to share your password. Tap “Share Password” and your Wi-Fi password is automatically sent to your friend’s iPhone and they’re able to join your Wi-Fi network.Discuss this article in our forums
