Other information

MSA and AAD accounts require different authorization methods. The snippets from this document are as follows:

Notice that we also pass the string "consumers" to the optional authority parameter. This is because Microsoft provides two different types of authentication - Microsoft Accounts (MSA) for "consumers", and Azure Active Directory (AAD) for "organizations". The "consumers" authority indicates we want the MSA option. If you're developing an enterprise app, use the string "organizations" instead.
