How to Share Your Wi-Fi Password on iPhone with friend

There are two prerequisites to use this feature: you must be running iOS 11 or later and you and your friend need to have each other listed as contacts in the Contacts app.If you have guests in your home, they might request you share the Wi-Fi password so they can cut down on their mobile data usage and enjoy safe browsing on your secure home Wi-Fi network. But password sharing should be done carefully and selectively. In some cases, you might not want to give out your password for security reasons. In others, it’s because the password is so long and complicated it’s a hassle to connect.

If you have two iOS devices, one already connected to the internet and one awaiting connection, you can share the Wi-Fi password without actually sharing it. In other words, you can use your iPhone to allow another device to connect to the private wireless network without manual password entry.

How to Share Your Wi-Fi Password on iPhone

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.
