iOS 16.3 for iPhone Launching This Week With These 4 New Features

In a recent press release, Apple confirmed that iOS 16.3 will be released to the public this week. The software update will be available for the iPhone 8 and newer and includes a handful of new features, changes, and bug fixes.


Below, we’ve recapped bigger features in iOS 16.3, including support for physical security keys as a two-factor authentication option for Apple ID accounts, worldwide availability of Advanced Data Protection for expanded iCloud encryption, and more.

Security Keys for Apple IDs

iOS 16.3 enables a new Security Keys for Apple ID feature, giving users the option to use hardware security keys to further protect their account. For users who enable this feature, Security Keys strengthens Apple’s two-factor authentication by requiring a physical security key as a second factor instead of a verification code from another Apple device.

Apple does not plan to release its own hardware security keys. The feature will rely on third-party security keys available from brands like Yubico, such as the YubiKey 5Ci, which has both Lightning and USB-C connectors for use with iPhones, iPads, and Macs.

Advanced Data Protection (Worldwide)

Starting with iOS 16.3, Advanced Data Protection will be available globally, giving users the option to enable end-to-end encryption for many additional iCloud data categories, including Photos, Notes, Voice Memos, Messages backups, device backups, and more. The security feature first launched in the US with iOS 16.2 in December.

By default, Apple stores encryption keys for some iCloud data types on its servers to ensure that users can recover their data if they lose access to their Apple ID account. If a user enables Advanced Data Protection, the encryption keys are deleted from Apple’s servers and stored on a user’s devices only, preventing Apple, law enforcement, or anyone else from accessing the data, even if iCloud servers were to be breached.

All of a user’s devices must be updated to software versions that support Advanced Data Protection in their country to use the feature. Outside the US, this includes iOS 16.3, iPadOS 16.3, macOS 13.2, tvOS 16.3, and watchOS 9.3.

Available in 41mm and 45mm sizes, the $49 band features the word “Unity” woven into the fabric with red, green, and black yarns that pay homage to the Pan-African flag, according to Apple. The band is available to order on Apple’s online store, and will be available in select ‌Apple Store‌ locations beginning Tuesday, January 24.

Second-Generation HomePod Support

Apple recently introduced a second-generation HomePod with virtually the same design as the full-size HomePod that was discontinued in March 2021, and iOS 16.3 will include software support for the smart speaker.

The new HomePod features five tweeters and four microphones (two fewer than the original), an S7 chip for computational audio, a U1 chip for handling off music from an iPhone, and a new temperature and humidity sensor. The speaker continues to revolve around Siri and has Matter support for controlling HomeKit and other smart home accessories.

The new HomePod can be pre-ordered now at Apple’s online store for $299, with white and midnight color options available. In-store availability and deliveries to customers will begin Friday, February 3 in the US and select other countries.
