Tenant Info

Everything Microsoft publicly tells about a Microsoft 365 tenant: name, ID, domains, region, sign-in type and endpoints

How it works

The passport is assembled from three public Microsoft endpoints: the SharePoint authentication realm, the user realm discovery used by the sign-in page, and the OpenID configuration of the tenant.

  1. Paste a link

    Any SharePoint Online or OneDrive address: a site, a document library, a file or the admin center. A tenant domain or just the tenant name works too.

  2. We ask Microsoft

    The host is reduced to the tenant name and checked against SharePoint Online and the Microsoft Entra OpenID endpoint. Nothing is sent to the tenant itself.

  3. Get the passport

    Organization name, tenant ID, confirmed domains, region, managed or federated sign-in and the OpenID endpoints — ready to copy.

What the passport is good for

Before configuring cross-tenant access, B2B collaboration or a multi-tenant app it helps to know who the tenant belongs to, whether sign-in is federated, in which region data is stored and which endpoints to use.

Requests go only to Microsoft’s public endpoints; the links you enter are not stored.
