 - The user account that you add as the first owner will have full administrative access to configure and manage the organization.
 
-- Converting a user account to an organization will delete all of the user's personal access tokens. See [Create an access token](/manuals/security/for-developers/access-tokens.md#create-an-access-token) for steps on creating personal access tokens after converting the user account.
