This is a minor quality-of-life improvement but it’s still notable.
For example, if you’re at a family member’s house and you don’t know their Wi-Fi password but you’ve previously connected to their home network, there’s no way to view it to connect other devices (this always happens to me with the Nintendo Switch).
With iOS 16, all you need to do is open the Wi-Fi section of the Settings app and select the network you’re connected to.
Next, you’ll see a new ‘Password’ option that appears after you authenticate your identity with Face ID, Touch ID or a passcode.
You can find an in-depth look at the rest of iOS 16 here. For all of the Apple news from WWDC 2022, follow this link.
