A seamless login future is coming for all Apple users. Starting with iOS 16 and macOS Ventura, Apple offers built-in support for passkeys. You can add these new cryptographically generated keys directly to your iCloud Keychain and they’ll sync across all your devices using end-to-end encryption.

As long as a service, app, or website supports passkeys, you’ll be able to generate them and log into your account without ever needing a password, SMS 2FA, or an authenticator app. Here’s how to set one up to work with your iCloud keychain across all of your devices.
