Users of Arc and Dia browsers have something to look forward to after developer Brian Michel shared an internal screenshot showing iCloud-based Passkey support has landed in the main codebase. The feature will soon roll out to both browsers, bringing them up to speed with Chrome’s existing implementation.
The announcement came through an X exchange when user Jason asked Arc and Dia’s CEO Josh Miller about native macOS keychain Passkeys support in Dia. Miller responded by sharing Michel’s internal message confirming the code had just been merged, calling it “a Brian Michel special”.
Michel noted that this update allows both browsers to request access to iCloud-based Passkeys for more secure web app logins, putting them at parity with Chrome while removing barriers for users who rely on Apple Password and iCloud Keychain instead of third-party password managers like 1Password.
The timing couldn’t be better for users who’ve been frustrated by the lack of system-level passkey integration. Many Arc users have reported having to pull out their iPhones to scan QR codes when logging into Apple.com, despite passkeys working smoothly with dedicated password manager integrations. This limitation affected not just iCloud passwords but also third-party managers that rely on macOS’s system integration, such as Strongbox.
So for users who’ve submitted feedback about this feature multiple times over the past two years, the wait appears to be finally over.
The feature is already available in Arc’s Early Bird Builds (Version 1.120.0), where some users have confirmed they can sign into Apple.com using iCloud Passkeys. While there’s no official timeline for the stable release, the fact that it’s already in testing suggests a broader rollout won’t be far behind.
With Google Chrome’s agentic browsing experience on the horizon, it’s good to see the folks at The Browser Company adding useful features left and right. The more users they manage to win over, the better their odds at surviving the AI browser war.
