2. Requirements for Setting Up Passkeys on iOS#

Passkeys provide an easy and secure way to log in to supported sites and applications without passwords by relying on Face ID or Touch ID to identify you. Your iOS device stores the passkey in the iCloud Keychain—often referred to as the icloud passkey feature—therefore you must be running iOS 16, iPadOS 16, macOS Ventura, tvOS 16 or later, and need an activated iCloud Keychain for optimal security.

iPadiPadOS 16+
MacBook / iMac / Mac MinimacOS Ventura+
Apple TVtvOS 16+

To save a passkey on your iOS, you need an activated iCloud Keychain which serves as an icloud passkey repository. If you don't have the iCloud Keychain turned on when you try to create a passkey, you will be prompted to do so (“To save a passkey, you need to enable iCloud Keychain. You can enable iCloud Keychain in Apple ID > iCloud > Passwords and Keychain in the Settings app”). Passkeys also require that you have two-factor authentication (2FA) enabled for your Apple ID.

3. Benefits of Enabling Apple Passkeys on iOS#

  • Enhanced Security: By enabling passkeys on iOS, you use public key cryptography, which means the private key never leaves the Apple device, reducing the risk of phishing and credential theft. This cryptographic method is significantly more secure than traditional passwords, and whether you refer to it as an ios passkey or an apple passkey, the protection remains robust.

  • Simpler User Experience: Passkeys eliminate the need to remember and manage multiple passwords. Authentication with a passkey on iOS typically involves just a biometric check (like Face ID or Touch ID) or a device PIN, making the process much faster and more user-friendly. If you’ve ever wondered how to use passkey on iPhone, the convenience is now at your fingertips.

  • Cross-Device Compatibility: Apple passkeys on iOS are always stored in your iCloud Keychain as an icloud passkey. Thus, passkeys created on one iOS device (or passkey iphone) can be used across other Apple devices signed into the same iCloud account, and they can also be accessed on non-Apple devices via QR codes or other methods, ensuring effective passkey linked devices iphone management.

5. How to Log In with Passkeys on iOS#

Passkeys are available on all your devices where you are logged in with the same Apple ID, as they are synced via the iCloud Keychain—providing a consistent experience akin to managing your icloud passkey across passkey linked devices iphone.

The instructions for logging in with a passkey can vary depending on the app, website, or browser, but they typically consist of steps similar to the ones below:

  1. On your iOS device, go to the website or app and tap the username (can be any unique identifier, email address, or phone number) input field on the login screen.
  2. Login
    • Login with Conditional UI: Tap the suggested username that appears at the bottom of the screen or on top of the keyboard.
    • Regular login: If the username doesn't appear automatically in an autofill menu, or you want to use a different one, enter it.
  3. Use Face ID or Touch ID to complete the login. If you didn’t set up Face ID or Touch ID on your iOS device, enter your device passcode (the code you use to unlock your device).
  4. The passkey you saved completes the login automatically.

If you want to log in on your current iOS device using a passkey that is stored on a different device not associated with your Apple ID, you may be able to select “Other Options” (or similar) instead of “Continue”. Then, follow the onscreen instructions, where you can either use another “iPhone, iPad or Android device” (read more about Cross-Device authentication with QR codes and Bluetooth in this blog post) or a “Security key” (e.g. YubiKey). This is particularly useful if you're wondering how to get passkey on iPhone from another device.

6. Using Passkeys Saved on Your iPhone on Other Devices#

Using a passkey saved on your iPhone to log in on another device is simple and secure.

  2. Click “Login” and you should see a Face ID menu from iOS.

  3. Select "Other options," "Passkey from nearby device," or similar, then follow the onscreen instructions to display a QR code on the screen.

  1. On the other phone where you scanned the QR code, select the passkey you want to use. By clicking on it and confirming via Face ID, Touch ID, or passcode, the login process is also completed.

7. Integrating Passkeys with Password Managers on iOS#

Integrate passkeys with third-party password managers on iOS to enhance your cross-platform usability.

8. Passkeys on iOS FAQ#

8.1 What if biometric authentication (e.g. Face ID sensor) is broken?#

You can always use our iPhone’s passcode instead of biometric authentication (e.g. Face ID, Touch ID), making it clear how to use passkey on iPhone even when biometrics fail.

8.2 Can I enable passkeys on iOS for use with Android?#

Yes, passkeys can be used across different platforms, including Android. Here’s how it works:

  1. Platform Independence: Passkeys are not restricted to devices, browsers, or operating systems from a single company. While they may be anchored to a specific technology suite by default (such as Windows Hello for Windows, Google Password Manager for Android, and iCloud Keychain for iOS and macOS), they are designed with cross-platform and cross-device compatibility in mind.
  2. Sharing Across Platforms: Passkeys can be used between different platforms and devices using QR codes and Bluetooth. This means you can seamlessly use a passkey generated on an iOS device on an Android device and vice versa.
  3. Backup and Synchronization: Passkeys are securely backed up in services like iCloud Keychain (the home of your icloud passkey) and Google Password Manager. For instance, if you attempt to log in to the same account on your Mac, iPhone, iPad, or Apple TV, you can simply use Face ID or your fingerprint to verify your identity. This ensures that passkeys are synced across all Apple devices connected to the same iCloud account.
  4. Third-Party Managers: Using third-party password managers such as 1Password or Dashlane allows you to use the same passkey on different platforms. These managers facilitate the synchronization and management of passkeys across various devices and operating systems, enhancing cross-platform usability.

In summary, while passkeys are initially tied to a specific platform's technology suite, they are inherently designed to be used across different platforms, ensuring a secure and seamless login experience regardless of the device or operating system you are using.

8.3 Can passkeys be shared?#

Yes, passkeys on iOS can be shared with other people via AirDrop.

9. Conclusion: How to Activate Passkeys on iOS#

In conclusion, activating passkeys on iOS is straightforward and offers enhanced security and ease of use. Whether you're curious about what is passkey on iphone, or need guidance on how to get passkey on iphone, this process integrates a robust system that relies on icloud passkey storage for easy access. Passkey authentication is integrated into iOS 16 and later versions, enabling users to conveniently use passkeys for signing in to applications and websites. To use passkeys on iOS, you need to activate your iCloud Keychain, which securely stores them. Consequently, your passkeys become functional across different Apple devices, providing a seamless and secure login experience every time.
