About Security Keys for Apple ID

Physical security keys provide extra protection for your Apple ID against phishing attacks.

Security Keys for Apple ID

Security Keys for Apple ID is an optional advanced security feature designed for people who want extra protection from targeted attacks, such as phishing or social engineering scams.

With two-factor authentication — which is designed to make sure that you're the only one who can access your Apple ID account — you need to provide two pieces of information to sign in with your Apple ID to a new device or on the web.

• The first piece of information is your Apple ID password.

• A security key can act as the second piece of information, instead of the six-digit verification code that is normally used.

Because you use a physical key instead of the six-digit code, security keys strengthen the two-factor authentication process and help prevent your second authentication factor from being intercepted or requested by an attacker.

What's required for Security Keys for Apple ID

• At least two FIDO® Certified* security keys that work with the Apple devices that you use on a regular basis.

• Two-factor authentication set up for your Apple ID.

• A modern web browser. If you can't use your security key to sign in on the web, update your browser to the latest version or try another browser.

• To sign in to Apple Watch, Apple TV, or HomePod after you set up security keys, you need an iPhone or iPad with a software version that supports security keys.

• To sign in to iCloud for Windows after you set up security keys, you need iCloud for Windows 15 or later.

What doesn't work with Security Keys for Apple ID

• You can't sign in to older devices that can't be updated to a software version that supports security keys.

• Child accounts and Managed Apple IDs aren't supported.

• Apple Watches that are paired with a family member's iPhone aren't supported. To use security keys, first set up your watch with your own iPhone.

Choose the right security keys

Security Keys for Apple ID works with any FIDO® Certified security key. Some good examples include:

• YubiKey 5C NFC (works with most Mac and iPhone models)

• YubiKey 5Ci (works with most Mac and iPhone models)

• FEITIAN ePass K9 NFC USB-A (works with older Mac models and most iPhone models)

If you choose a different security key, you should choose security keys that are FIDO® Certified, and have a connector that works with the Apple devices that you use on a regular basis.

For a complete list of certified keys from the FIDO Alliance, visit the FIDO® Certified Showcase.

Choose the right connectors for your device

Security keys with both near-field communication (NFC) and a USB-C connector work with most Apple devices.

Use Security Keys for Apple ID

When you use Security Keys for Apple ID, you need a trusted device or a security key to:

• Sign in with your Apple ID on a new device or on the web

• Reset your Apple ID password or unlock your Apple ID

• Add additional security keys or remove a security key

Keep your security keys in a safe place, and consider keeping a security key in more than one place. For example, keep one key at home and one key at work. If you're traveling, you might want to leave one of your security keys at home.
