Managing GuardDuty accounts by invitation
To manage accounts outside of your organization, you can use the legacy invitation method. When you use this method, your account is designated as a administrator account when another account accepts your invitation to become a member account.
Note
GuardDuty recommends using Amazon Organizations instead of GuardDuty invitations, to manage your member accounts. For more information, see Managing accounts with Amazon Organizations.
If your account is not an administrator account, you can accept an invitation from another account. When you accept, your account becomes a member account. An Amazon account cannot be a GuardDuty administrator account and member account at the same time.
When you accept an invitation from one account, you can't accept an invitation from another account. To accept an invitation from another account, you will first need to disassociate your account from the existing administrator account. Alternatively, the administrator account can also disassociate and remove your account from their organization.
Accounts associated by invitation have the same overall administrator account-to-member relationship as accounts associated by Amazon Organizations, as described in Understanding the relationship between GuardDuty administrator account and member accounts. However, invitation administrator account users cannot enable GuardDuty on behalf of associated member accounts or view other non-member accounts within their Amazon Organizations organization.
Important
Cross-regional data transfer may occur when GuardDuty creates member accounts using this method. In order to verify member accounts' email addresses, GuardDuty uses an email verification service that operates only in the US East (N. Virginia) Region.
