Apple has introduced a new version of the Magic Keyboard for Mac, which for the first time enables Touch ID for password-free unlocking of macOS.
The new Magic Keyboard, which Apple introduced as part of the iMac refresh during the “Spring Loaded” event presented has brought with it some changes that make the keyboard even more useful for the user. One of the most important changes is the introduction of Touch ID, a technology that was already available on the MacBook Pro.

It has its own Touch ID sensor that creates a secure channel to the Mac's Secure Enclave to protect the authentication process. The keyboard also includes function keys that can be used to trigger Spotlight, Dictation, and Do Not Disturb. At the bottom left, the Function key can also be used to initiate the input of emoji characters.

Magic Keyboard with Touch ID: Also available with numeric keypad
Apple also designed the keyboard to have a casing that matches the color of the iMac to ensure a consistent look. Versions with a numeric keypad are also available. In addition to the Magic Keyboards, Apple has also updated the Magic Mouse and Magic Trackpad to include the additional color options.

While Apple will ship the Magic Keyboard and Magic Mouse with the new iMac, it remains unclear how much the updated versions will cost separately.
