Auth0 now provides your own custom domain for login with a central authorization server.
Using Custom Domains to Brand Central Authorization Servers
Authenticating with a provider through a central authorization server provides you with a standards-based, maintainable, and secure login approach. This type of login also provides single sign-on benefits and a modern user experience. You can explore the benefits of this architecture further in this blog post.
For those who are not familiar with the concept, you may have noticed that you are always redirected to accounts.google.com when you log into Google sites such as Gmail or Youtube. Google has a central authorization server that is used across all of their applications and third-party apps.
Auth0 provides this same capability out of the box, allowing you to unify login for your own brand and products. Enabling Auth0's central authorization provider, Universal Login, is easy, straightforward, simple to configure, and can be customized to suit your brand.
Customers who prefer this experience to be served from their own domain, instead of
[your-account].auth0.com, can configure their own custom domain in Auth0. This feature is available for all paid customers (for tenants tagged as Development). Adding your own custom domain to an existing implementation only requires small code changes thoroughly detailed in our custom domain setup docs. Simple configuration can be completed within your Auth0 dashboard.

Benefits of Using a Custom Domain
By using a custom domain for your authentication page, you keep your users interacting with you within the context of your brand, which helps you build brand loyalty. Users are not redirected to a third-party site that breaks the branding context. This prevents users from becoming confused about whether or not they are still running a transaction or operation with you.
For example, if your Auth0 domain is
northwind.auth0.com, you can have your users to see, use, and remain on
"Using a custom domain with Auth0 allows your users to feel confident that they are providing their credentials to the right party. Authentication happens within the context of your brand."
Auth0 support for custom domains allows us to do the authentication heavy lifting for you without compromising your branding experience.
Brand loyalty from users is a pillar for the success of an organization of any size. One of the ways to build brand loyalty is by offering a consistent branding experience to users. It's important that your users always feel that they are interacting directly with you to avoid confusion or session abandonment.
From the security point-of-view, using Universal Login is the preferred way to handle end-user credentials. It allows you to have comprehensive control of authentication in one centralized place, as opposed to having individual applications handling credentials. Consequently, having your authentication services contained in one place will make your application architecture more maintainable. Applications are only given the access they need and authentication services can be scaled easily.
You can mitigate certain phishing attacks when your users expect to run transactions within your domain. Having that domain consistency will allow your users to easily and quickly reject phishing attempts.
Universal Login also offers you simplicity as an implementation advantage. You don't have to worry about integrating login user interfaces into different applications. When you use Auth0 Universal Login, you get all the features you need in the fastest possible way: redirecting to a common login interface. Adding custom domains to this workflow creates a seamless experience for your developers and end-users.
Custom Domain Authentication Features
Core Auth0 features and flows support the use of custom domains:
- OAuth 2.0/OIDC-Compliant Flows (those using the
- Database and Social Connections.
- SAML Clients and Connections.
- A full list of features supporting the use of custom domains is available in the feature section of our custom domains document. New features, such as enterprise connections, will be added to the list as they become available. Keep an eye on that space!
How It Works
To configure your custom domain with Auth0, go to your account settings, select Custom Domains, add your own domain, and follow the instructions.
Your existing integrations using your
[your-account].auth0.com domain will continue to work. After migration to your custom domain is complete, users will have to log in again since existing sessions will no longer be valid.
Custom Domain Self-Service
Different than other solutions, Auth0 not only gives you the option to use a custom domain, but Auth0 also empowers you with full control over setting up and using your custom domain for authentication. Flexible self-service options are available through our Dashboard for you to directly handle selecting, verifying, and implementing your custom domain. You don't have to wait on us for anything to complete this process. You are in charge.
