in the ios password app you can tap on the button to export data to other app. it will show you the list of installed apps that can import them. works with passwords and passkeys.

I moved all of them from my iphone to a selfhosted bitwarden in two minutes.

Ok, good to know that.

I'm surprised selfhosted services would be allowed in that list. Isn't there the "risk" that you can then extract the raw key from your selfhosted instance?
