2fa

The session "Streamline sign-in with passkey upgrades and credential managers" at WWDC 2024 covers various aspects of improving sign-in security and user experience by transitioning from traditional passwords to passkeys. Here are some key points related to two-factor authentication (2FA) and passkeys:

1. Passkeys vs. Traditional 2FA:

   • Passkeys are designed to be more secure than traditional 2FA methods, which often rely on phishable factors like passwords, SMS, email, push notifications, and time-based codes (Streamline sign-in with passkey upgrades and credential managers).
   • The industry is moving towards unfishable authentication mechanisms such as passkeys to prevent phishing attacks (Streamline sign-in with passkey upgrades and credential managers).

2. Automatic Passkey Upgrades:

   • Automatic passkey upgrades can help transition users from passwords to passkeys seamlessly, without interruptions or upsell screens (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. Verification Codes:

   • For apps and websites that offer time-based verification codes, setting up that code can be made a one-tap experience by offering an OTP Auth link in addition to the standard QR code (Streamline sign-in with passkey upgrades and credential managers).
   • The new Passwords app in macOS Sequoia, iOS 18, and VisionOS 2 includes a section for verification codes, making it easy to look up and copy a code, similar to a dedicated authenticator app (Streamline sign-in with passkey upgrades and credential managers).
