How do I use my Apple ID password with Face ID?

You can't directly use Face ID as your Apple ID password. Instead, Face ID can be used to replace the need to enter your Apple ID password in many situations. You can use Face ID for a variety of functions instead of having to type your Apple ID password each time, such as unlocking your device, making purchases, and auto-filling passwords.

How to Set Up Face ID for Apple ID Related Actions:

To enable Face ID for functions that would normally require your Apple ID password, follow these steps:

1. Open Settings: On your iPhone, find and tap the "Settings" app icon.
2. Navigate to Face ID & Passcode: Scroll down and tap on "Face ID & Passcode." You might be prompted to enter your device passcode.
3. Enable Face ID for Desired Actions: Under the "Use Face ID For" section, you will find a list of options.
   • Toggle on the options you want to use with Face ID, such as:
     • iPhone Unlock: Use Face ID to unlock your iPhone.
     • Apple Pay: Authorize payments with Face ID.
     • iTunes & App Store: Use Face ID to authorize downloads and purchases.
     • Password Autofill: Allow Face ID to fill in saved passwords automatically.
     • Other Apps: Many third-party apps offer Face ID login. These will appear in this list as well, if you've enabled them.

Practical Examples of How Face ID Replaces Apple ID Password Usage:

• Unlocking Your iPhone: Instead of typing your device passcode or Apple ID password, Face ID will authenticate your identity when you look at your iPhone.
• Making Purchases: When making a purchase in the App Store or using Apple Pay, you can authorize the transaction using Face ID instead of having to enter your Apple ID password.
• Auto-filling Passwords: When logging into a website or app, Face ID can be used to automatically fill in your saved password eliminating the need to type it manually.

Important Considerations:

• Face ID Setup: Face ID needs to be set up on your device before you can use it with your Apple ID. If you haven't already set it up, follow the onscreen prompts in the "Face ID & Passcode" menu to configure it.
• Fallback: If Face ID fails to recognize your face, you may be asked to enter your device passcode or Apple ID password as an alternative method of authentication.
• Security: Face ID is designed to be secure. However, keep your device locked when not in use to protect it from unauthorized access.

In summary, Face ID doesn't become your Apple ID password. Instead, it's a biometric authentication method that can replace the need to enter your Apple ID password or device passcode for various functions on your Apple device after you set it up in settings.
