Apple iOS 16.3 Release with Support for Hardware Security Keys

Apple announced iOS 16.3 release with long-awaited support for hardware security keys to provide extra protection against phishing attacks and unauthorized access to your devices. This means you can now secure your Apple ID with FIDO-certified physical key.

These hardware security keys are small physical devices that look like thumb drives that support USB-C or Near-field communication (NFC) to connect to a Mac or iPhone. The idea of hardware security keys is to use them as an additional verification step when using two-factor authentication for Apple IDs rather than the regular six-digit verification code shown on devices.

Security keys must be in close proximity of the Apple device to authenticate a login. This provides greater protection against hackers trying to log into your account remotely. Through common methods such as phishing attacks targetted at stealing Apple ID credentials and the one-time passcodes sent via 2FA verifications.

Other notable addition to the Apple iOS 16.3 release includes support for HomePod (2nd gen), watchOS 9.3, and a host of other fixes as listed:

  • New Unity wallpaper honors Black history and culture in celebration of Black History Month
  • Security Keys for Apple ID allow users to strengthen the security of their account by requiring a physical security key as part of the two factor authentication sign in process on new devices
