How can I get a list of all the Azure AD instances associated with this account?

I am not sure whether Microsoft Graph api expose the api call to get a list of all the Azure AD instances associated with this account . But i noticed in azure new portal , i could choose Multiple Windows Azure Active Directories by clicking my user name on top right part of portal . Use Fiddler you could find api call which portal use to get multiple Windows Azure Active Directories information :

https://ms.portal.azure.com/AzureHubs/api/tenants/List

Then you could add Windows Azure Service Management API in required permissions in your app :

Then using authorization code flow , you need to get access token for Windows Azure Service Management API by setting resource :https://management.core.windows.net/ .

After you get the access token , you could try below api calls to get all the Azure Active Directories :

POST https://ms.portal.azure.com/AzureHubs/api/tenants/List
Authorization: Bearer xxxxx

The result :

If your account is a microsft account and want to authenticate with app , you could add the account as external user in AAD .
