Auth0 Multiple (MCD) feature offers powerful flexibility, allowing organizations to manage diverse branding, regional requirements, and partner integrations all from a single Auth0 tenant. This simplifies identity management while providing a seamless, branded experience for your users.

​
Single brand, multiple top-level domains (TLDs)

Some businesses, like airlines, require different top-level domain names (for example: .com, .co.uk, .com.au) even with a single user base. This is often driven by jurisdictional regulations or customer preferences. With MCD, you can easily create this setup in Auth0, running a single tenant with a unified user store while offering multiple top-level domains. For example, your primary website might be exampleco.com, but you can also operate exampleco.co.uk and exampleco.com.au.

​
Multiple brands, single user base

It is common for businesses to own several brands, each with its own domain, but benefit from a single user store and other unified features of a single Auth0 tenant. In retail, for instance, a company might manage distinct brands offering upscale home furniture (brand1-home-furniture.com) and office furniture (brand2-office-furniture.com). MCD allows these brands to maintain separate domain names while sharing a centralized user store and Auth0 setup.

White-labeled B2B SaaS

Many SaaS providers offer their services in a white-labeled model. Imagine job-saas.com, a platform for managing job applications. Client companies can host job-saas.com services under a subdomain of their own and customize its look and feel, such as jobs.client-a.com and jobs.client-b.com. With MCD, job-saas.com can maintain its entire Auth0 configuration in a single tenant, yet offer different organizations and custom domains directly to its customers.
