> We'll explore key updates including [...] and the secure import/export of passkeys

Have they shared any details about if this is actually cross-provider/platform import/export? I feel like if Apple doesn't outright share those details, they're talking about import/export within the Apple ecosystem.

No, in this case it is actually an industry standard: https://fidoalliance.org/specifications-credential-exchange-...

Nothing of the info Apple published so far seems to indicate that they'll implement that. And again, based on the track record of Apple, feels unlikely they won't implement something on their own.

From the video cited upthread: "This transfer uses a data schema that was built in collaboration with the members of the FIDO Alliance. It standardizes the data format for passkeys, passwords, verification codes, and more data types"

I worked on this standard and we’re all excited that it’s rolling out to most of not all password managers and platforms.

Let’s see — Apples track record of interoperability isn’t great unless dragged by regulatory bodies. Managing private emails at scale to migrate away from Apple for instance is wildly painful.
