Passkeys

Passkeys were a significant topic at WWDC 2024, with multiple sessions discussing their benefits and implementation. Here are some key points:

1. What’s new in privacy:

   • 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 enhances account security without requiring changes to the login flow.

2. Streamline sign-in with passkey upgrades and credential managers:

   • Passkeys eliminate the need for multiple sign-in steps and are more secure against phishing. They can't be forgotten and are less likely to need a reset. The session also covers automatic passkey upgrades, which can create passkeys without interrupting the user experience. (Streamline sign-in with passkey upgrades and credential managers)
   • Credential managers can now participate in automatic passkey upgrades and fill time-based verification codes, usernames, passwords, or one-time codes into any text field. (Streamline sign-in with passkey upgrades and credential managers)

3. Platforms State of the Union:

   • A new registration API creates passkeys automatically for eligible users the next time they sign into your app, making future sign-ins faster and more secure. (Platforms State of the Union)
