If you’re asking about passkeys and AASA, the most relevant WWDC coverage here is automatic passkey upgrades.

What Apple said

  • Passkeys are a standards-based replacement for passwords that are more secure and resistant to phishing.
  • With automatic passkey upgrades, an app or website can create a passkey automatically right after a successful password sign-in.
  • This works without changing the login flow for passwords, and in the best case it creates the passkey with no interruption to the user.

How it relates to AASA

The retrieved WWDC context doesn’t specifically mention AASA by name, so I can’t confirm details about the AASA file from these segments alone. But the passkey upgrade flow is covered in:

  • Streamline sign-in with passkey upgrades and credential managers
  • What’s new in privacy
  • What’s new in passkeys

Relevant WWDC sessions

  • Streamline sign-in with passkey upgrades and credential managers — explains automatic passkey upgrades in apps and on the web.
  • What’s new in passkeys — covers the newer passkey APIs and the upgrade flow in more detail.
  • What’s new in privacy — mentions automatic passkey upgrades in iOS 18 and macOS Sequoia.

If you want, I can also help with what AASA does for passkeys in general, but I’d need context that explicitly covers it.
