That would make it extractable and syncable to other hosts. That's fine if that's what you want but it's an important distinction.

yes, that's exactly what I want :) (and the private key is only living inside 1Password and isn't extractable from there)

		Typically you want to generate one key per host. That's why, by default, a new key bears a user@host identifier. If it gets compromised, you need to revoke this one key only and still maintain access from, presumably, other systems of yours.

		You’re mistaken. 1Password syncs keys. Therefore, they’re extractable.
