Translate resource tenant ID to name

Question

Our sign-in logs show numerous successful single-factor authentication logins even though we enforce multi-factor authentication. The details for these indicate the user is connecting with an external resource. It gives the resource ID and resource tenant ID. I would like to be able to determine what company has this ID. I found numerous posts on how to obtain my own tenant name, but nothing on how to obtain another tenant's name. I view this as similar to whois for internet domain names. How can I determine the name of an entity with a specific tenant ID?

Hi @Mongoose

Thank one more time for your reply back.

If you want to use a P1/P2 license, for instance you can activate a Free trial for P2 license and then run the command.

Hey!

Looks like you can simply search for the "Resource Tenant ID" in your "External Identities | Cross-tenant access settings". Here you'll see the a list of external tenants with inbound and outbound policies. The external tenants here have a "friendly display name", but you will get a hit if you search for the "Resource Tenant ID" :)
