Dynamics 365 Business Central: Quickly find the tenant ID from the domain name without signing in

Hi, Readers.
Today I would like to share another mini tip, how to quickly find the tenant ID from the domain name without signing in.
Your Microsoft 365 tenant ID is a globally unique identifier (GUID) that is different than your organization name or domain.
Generally, as a technician at Business Central, we have the following ways to find the Tenant Id.
1. From Microsoft 365 admin center:

2. From Azure Portal:

3. From Business Central:

4. Using AL Method: Dynamics 365 Business Central: How to get the Azure Active Directory tenant domain name and ID via AL (codeunit 433 “Azure AD Tenant”)

But no matter which one, we need to sign in first. There is actually a very simple way here, using the website below:
