How can I integrate passkeys?

To integrate passkeys into your app, you can follow these steps based on the sessions from WWDC 2024:

Automatic Passkey Upgrades: Passkeys are a standards-based password replacement that are easier to use, more secure, and resistant to phishing. In iOS 18 and macOS, apps can automatically upgrade existing accounts to use passkeys during sign-in. This means you don't have to adjust your login flow to accommodate them. By adopting passkeys, you provide users with a secure and easy way to sign in, reducing the burden of managing passwords. For more details, you can refer to the session What’s new in privacy.
Streamline Sign-In with Passkey Upgrades: The session "Streamline sign-in with passkey upgrades and credential managers" provides a detailed explanation of how to implement passkeys. It discusses the transition from passwords to passkeys and how automatic passkey upgrades can facilitate this transition. The session also covers the use of credential managers to support passkey upgrades and the new features available for them. You can start learning about this from the chapter Automatic passkey upgrades.
Credential Managers: Credential managers can participate in automatic passkey upgrades and now support filling time-based verification codes, usernames, passwords, or one-time codes into any text field. This is part of the improvements for credential managers discussed in the session. You can find more information in the chapter Improvements for credential managers.

By following these guidelines and utilizing the resources provided in the sessions, you can effectively integrate passkeys into your app, enhancing security and user experience.
