FWIW: MacOS and iOS allow third party password managers to ingrate directly into AuthenticationServices and list passkeys in the native passkey UI through a "Credential Provider" extension. And it's documented how: https://developer.apple.com/documentation/authenticationserv...
This is the same Credential Provider API they already have to integrate with to show the password autofill in iOS so there is already _some_ code for this.
1Password _could_ just integrate with the native UI. But they chose not to.
This however means shipping a native app which is a lot more heavy-weight than shipping a web extension.
I opened an issue in the webauthn repo about giving an API for WebExtensions to hook into the passkey autocomplete but there hasn't been any traction or appetite for it unfortunately :(

I mean, I kind of understand this; they're going to have to do the WebExtension either way, since there's no standard API across platforms.
On the other hand. They already integrate with this API for their iOS app as it's the only way to do password autocomplete on iOS. Why not extend that use to MacOS?
