objectId

The immutable identifier for an object in the Microsoft identity system, in this case, a user account. This ID uniquely identifies the user across applications - two different applications signing in the same user will receive the same value in the oid claim. The Microsoft Graph will return this ID as the id property for a given user account. Because the oid allows multiple apps to correlate users, the profile scope is required to receive this claim. Note that if a single user exists in multiple tenants, the user will contain a different object ID in each tenant - they’re considered different accounts, even though the user logs into each account with the same credentials. The oid claim is a GUID and cannot be reused.
