How to get Azure Active Directory Tenant ID in Azure portal ?

My question is : Is it possible to get the azure active directory tenant id without using powershell command ?

I found this two blogs and with this help, I'm already able to get the tenant ID and subscriptions ID from powershell.  Is it the only way to retreive the tenant ?

Thanks,
