When you install and configure the plugin then by default only only users with accounts in your own organizational directory are able to sign into your WordPress website. However, if you intend to make (parts of) your (private) WordPress extranet / website available to customers, partners or basically any user with a valid Microsoft login, then you can do so by adding support for:
- Accounts in any organizational directory (Any Azure AD directory – Multitenant),
- And / or personal Microsoft accounts (MSAL e.g. Outlook, Skype, Xbox).
Guest users versus multi-tenant
This feature relies on an administrator enabling multi-tenancy for your (WordPress) application. This basically means that you allow users from any other organizational directories (or even any user with a personal Microsoft account) to access your content, as soon as they have authenticated successfully.
