Just to be clear, are you asking about syncing passkeys across devices (ostensibly within the same ecosystem)? Or exporting passkeys between different ecosystems? The typical use case for passkeys is that you can register multiple passkeys on an account, representing each authorized device. Each device can have its own distinct passkey provider. Services like 1Password allow you to sync passkeys between different devices, but those all stay within the 1Password ecosystem. 1Password also lets you export passwords and passkeys to different credential managers, but that's a one-off operation, presumably because you're leaving that ecosystem for another.

The article was specifically upset with Google and Apple for not letting you export across ecosystems. So, I'm specifically asking how they think that could work. Am I misreading the article on that?

  Got it. I think import/export is a solved problem, assuming you're OK with (at least temporarily) having your secrets unencrypted. Password managers already do this. It's not a technical issue that's preventing Apple or Google from making their passkeys importable/exportable.

    This doesn't seem to address my question, though? That is, agreed it is not a technical issue, but it is a security one? As you stated, if you are ok with your secrets being unencrypted, then sharing is totally possible. But this seems to walk headlong into having to trust everyone that you share the unencrypted secret with?

      Hi there, it is up to individual websites whether they require passkeys or passkeys + 2FA etc.. It is also important to note that most attacks are phishing-based, and passkeys are phishing-resistant, and will only work on the originating website. Proton Sentinel also helps to protect account takeovers, even when an attacker has stolen your password.
