Passkeys are a new, standards-based password replacement that offer a more secure and user-friendly way to sign in to apps and websites. They are resistant to phishing and eliminate the need for users to remember or manage passwords. Passkeys can be automatically upgraded from existing accounts, making the transition seamless for users.

In iOS 18 and macOS, apps can automatically upgrade existing accounts to use passkeys during sign-in, without requiring changes to the login flow. This automatic upgrade process is designed to be smooth and unobtrusive, enhancing security without interrupting the user experience.

The session titled "Streamline sign-in with passkey upgrades and credential managers" at WWDC 2024 provides detailed insights into how passkeys work and how developers can implement them in their apps. It covers the automatic passkey upgrade sequence, improvements for credential managers, and the overall journey towards adopting passkeys.

For more information, you can watch the session Streamline sign-in with passkey upgrades and credential managers starting at the "Automatic passkey upgrades" chapter.
