Is there a limit to the number of multitenant, verified, app registrations?

Question

Wondering if there is any limits (implicit or explicit) with the number of multitanant app registrations. For example can we create 100 or even 1000s of multi-tenant app registrations?

I see on the documentation application-registration-limit-for-azure-tenant, that there is a limit to 50,000 AD resources, so I believe 50,000 would be an upper bound, but I wasn't sure if there is also any other limits to worry about?

Answer 1

There is no specific limit for App Registrations in a tenant, so yes, you could create hundreds or thousands of multi-tenant app registrations. There is a limit for the overall number of Directory Objects in a tenant, which includes, Users, Groups, Applications, servicePrincipals, and other resources.

As you mentioned, the default Directory Objects limit is 50,000, which gets extended to 300,000 when a verified domain is added to the tenant. You can get the limit further raised to 500,000 by opening a support ticket with Microsoft. If you have an Azure AD Premium license, you can get it raised beyond 500,000 limit by providing a business justification.
