Apple’s iOS has a feature built into it which enables a user to share Wi-Fi passwords between iOS devices bringing them close to each other. It makes use of Wi-Fi, Bluetooth, and the Apple ID of every single user so as to share the password.
Sharing your Wi-Fi password is somewhat provoking at times. Say for example, you have a Wi-Fi password that combines letters, numbers and special characters (symbols), it might prove an uneasy task if you want to share that password with a loved one. However, with the coming of iOS 11, sharing of Wi-Fi passwords has gotten easier on iPhones and iPads although there are things you need to go over before you can do so.
The first one is to ensure that each of the phones have their Wi-Fi and Bluetooth turned on. To do this, go to Settings, then Wi-Fi and Settings, and then toggle it on (do the same for the Bluetooth).
The next thing, you want to do is make sure that the Apple ID of each phone is available in the “email” section in Contacts, this is very crucial. This also should work if each of the devices share the same Apple ID.
To end, connect one of the devices to the Wi-Fi.
Then, head to the Settings and select Wi-Fi on the disconnected device.
Tap on the name of the network you want to join, once you have done this, you’ll get a password prompt.
Unlock the other iOS device and bring it close to the device you want to connect. After that, the device that’s already connected will receive a prompt asking if you want to share the Wi-Fi password. Tap “Share Password” and the other device will automatically receive the password and connect.
And that is all there is to it. The password box on the connecting device will autofill the password and connect.
