All green for Safari 18.4 (r215) on macOS! #passkeys featuredetect.passkeys.dev
A web page screenshot titled "WebAuthn Features and Capability Detection for Passkeys" for Safari 18.  The page lists 14 WebAuthn features related to passkeys, such as "Passkey Platform Authenticator", "Cross-Device Authentication", and "Conditional Get (Autofill UI)". Each feature is marked either "Available" or "Supported".  A disclaimer at the bottom states it's a developer resource and not intended for general user information about passkey support.

I wrote about how magic links (emailed one-time login links) frustrate me while explaining that they radically accept some fundamental truths. I argue that websites should layer passkeys on top of magic links to provide a seamless authentication experience for everyone. rmondello.com/2025/01/02/m...
