Apple released macOS Big Sur to the public on November 12. While there are a bunch of under-the-hood features that have been discovered so far, a previously undocumented feature is 2FA support for third-party Mac apps.

Ricky Mondello, an Apple Employee responsible for App/Website authentication and password management, took to Twitter today to disclose that Security Code AutoFill is available for all Mac apps.

Developers, although, have to explicitly include the feature within their apps if they want to add 2FA AutoFill functionality for users.

Security Code AutoFill is a handy feature that already exists on iOS as well as on the Mac. It lets users fill in two-factor authentication codes with a click.

On the Mac, it works while filling 2FA fields when a 2FA code appears in the Messages app on your iPhone. A prompt then appears below the 2FA field on the Mac and clicking it automatically fills the field.

Prior to Big Sur, Security Code AutoFill was limited to Safari. However, with Big Sur, Apple has extended the feature to support third-party apps as well.

In order to use 2FA AutoFill on your Mac, you need to make sure that Text Message Forwarding is enabled on your iPhone in the Messages tab within Settings.
