Apple has rolled out the second beta of iOS 16.3 / iPadOS 16.3 to developers.
Like the previous version, this test will still focus on fixing bugs and improving system stability.
Registered developers can now download the iOS 16.3 and iPadOS 16.3 configuration files from the Apple Developer Support Center to install the latest betas.

iOS 16.3 and iPadOS 16.3 added support for physical security keys that can be used as additional protection for your Apple ID.
This means users will set up a device as a second layer of two-factor authentication for their accounts. This security key is integrated with the device-to-device transfer process.
So, after authenticating your iPhone with a physical security key, if you buy a new iPhone, you don’t have to do it again as long as you use the settings transfer process between the two devices.
In addition to the security key, the beta adds instructions for using Handoff to transfer music from iPhone to HomePod.
In fact, switching from iPhone to HomePod is not a new feature, it has been there since the first generation of HomePod (discontinued in 2021).
In the HomePod mini, this feature works better and more accurately thanks to the U1 chip. You can play songs, podcasts, or make calls simply by holding your iPhone close to HomePod.
To help users familiarize themselves with the feature, Apple has included a new guide in iOS 16.3 that shows HomePod users the details of how to use the feature.
