Two-factor authentication is an extra layer of security for your Apple ID, designed to make sure that you’re the only one who can access your account—even if someone else knows your password1. When you sign in with your Apple ID for the first time on a new device or on the web, you need both your password and the six-digit verification code that’s automatically displayed on your trusted devices1. A trusted device is a device that you’ve already signed in to with your Apple ID and that can receive verification codes1. You can also add or remove trusted devices and phone numbers from your Apple ID account page1. Two features of two-factor authentication for a personal Apple ID are:

• It ensures that only the account’s owner can access the account. This is because you need to verify your identity with both your password and a verification code that is sent to a device or phone number that only you have access to1. This prevents unauthorized access to your account even if your password is compromised or stolen1.
• It can be accessed on trusted devices. This means that you can sign in to your Apple ID account on devices that you’ve already verified with two-factor authentication without needing to enter a verification code again1. This makes it easier and faster to access your account on devices that you use frequently and trust1.

 To start up a Mac with Apple silicon in macOS Recovery, you need to access the startup options screen first. This screen lets you choose different startup disks or modes, including macOS Recovery. To get to the startup options screen, you need to shut down your Mac completely, then press and hold the power button until you see “Loading startup options” on the screen. Then, you can click Options and click Continue to enter macOS Recovery1. The other options, pressing and holding the Shift key or Command-R, are not valid ways to start up a Mac with Apple silicon in macOS Recovery. These methods work on Intel-based Macs, but not on Macs with Apple silicon2. References: 1 Use macOS Recovery on a Mac with Apple silicon - Apple Support 2 Intro to macOS Recovery - Apple Support

Face ID is a biometric authentication method that allows you to securely unlock your iPhone or iPad, authenticate purchases, sign in to apps, and more, all with just a glance. However, there are situations where Face ID is not permitted and you need to enter your passcode instead. According to the Apple Device Support Reference Materials1, these situations include:

• The device has just been turned on or restarted.
• The user hasn’t used their passcode or password to unlock their device for 156 hours (six and a half days), and the user hasn’t used a biometric to unlock their device in 4 hours.
• The device hasn’t been unlocked for more than 48 hours.

Therefore, the correct answer is C, D, and E.

 FileVault is a feature that encrypts the data on your Mac’s startup disk, making it more secure. To unlock your Mac, you need to enter your account password or a recovery key. A recovery key is a 28-character code that is generated when you turn on FileVault. You can choose to store it in iCloud or write it down and keep it in a safe place. An iCloud account and password can also be used to reset your FileVault password, if you enabled this option when you turned on FileVault. The other options, authenticator app, using a trusted device, and SMS verification code, are not valid ways to reset a FileVault password on a Mac. References: 1 Use FileVault to encrypt the startup disk on your Mac - Apple Support 2 Reset a macOS User Password - Kandji 3 How to unlock your Mac with its Recovery Key and FileVault active - Macworld
