I have a few AWS accounts where I manage DNS addresses and ACM SSL certificates. I have a top-level.com domain in one account and another account manages subdomain.top-level.com. I created some SSL certificates with ACM on the top account for example: example.subdomain.top-level.com. But now I'd like to use the same certificate in my subdomain account. Is there a way to share these certificates between my accounts?
Reply from Amazon:
... Unfortunately it is not possible to share ACM certificates across accounts at this time.
But I got a hint that i'm not the only one asking. So it may be a feature in the future. And it will help people who support Certificate Pinning.
