Introduction to Apple Passkeys on iOS

Apple's passkeys provide a secure, passwordless authentication method that leverages biometrics like Face ID and Touch ID. By storing passkeys in the iCloud Keychain, users can enjoy a seamless login experience across all Apple devices running iOS 16, iPadOS 16, macOS Ventura, tvOS 16, or later versions.

Requirements for Enabling Passkeys on iOS

To enable passkeys, ensure your iOS device is updated to at least iOS 16 and that iCloud Keychain is activated. Additionally, two-factor authentication (2FA) must be enabled for your Apple ID. Without these prerequisites, you won't be able to create or store passkeys.

Benefits of Using Apple Passkeys

Passkeys offer enhanced security by using public key cryptography, ensuring that private keys never leave your device, significantly reducing the risk of phishing and credential theft. The user experience is also simplified, as passkeys eliminate the need to remember passwords, relying instead on a quick biometric check or device PIN.

Steps to Set Up Passkeys on Your iOS Device

1. Update and Enable: Make sure your iOS device meets the required OS version and has iCloud Keychain and 2FA enabled.
2. Create Passkeys: When creating a new account or logging into a supported app or website, you'll be prompted to save a passkey. Follow the onscreen instructions to finalize the setup.
3. Manage Passkeys: Saved passkeys can be managed under Settings > Passwords. They can coexist with traditional passwords for the same account.

Logging In with Passkeys

Once passkeys are set up, logging in is straightforward. Visit the login page of a supported app or website, select your username, and authenticate using Face ID, Touch ID, or your device passcode. This method is secure and can be used across all devices logged into the same iCloud account.

Cross-Device Usage of Passkeys

Passkeys saved on your iPhone can be used on other devices, including non-Apple platforms, through QR codes or Bluetooth. This cross-platform compatibility makes passkeys versatile, enabling a secure login experience across different operating systems.

Integrating Passkeys with Password Managers

For those using third-party password managers like Dashlane or 1Password, passkeys can be stored and synced across various devices and platforms. This integration enhances the usability of passkeys, making them accessible regardless of the device or operating system.

Conclusion

Activating passkeys on iOS is a straightforward process that significantly enhances both security and convenience. By enabling passkeys, you reduce the risk of password-related breaches while simplifying your login experience across all your devices. Read more details in the full blog post.
