Yes you can. You can export your passkeys and then import them into whatever android password manager, or 1Password.

I was under the impression that most credential managers won't allow you to export a passkey to a plain text format, but will only allow limited app-to-app transfer of keys (with a limited selection of compatible apps only)

I want to import them in Android nit another app and you can export to an Android app only to another app on your iPhone
