Understanding your application is key to understanding how Auth0 can be leveraged to meet your needs. From experience, our most successful customers start with a visualization of their proposed - or in many cases existing - architecture and use this as a basis for reference as they progress. Understanding where your application fits within your organization is also important; Auth0 Accounts and Tenants form the basis for the grouping and structuring of Auth0 assets, and it may be that you’ll need to leverage an existing Auth0 deployment in order to integrate with Single Sign-on (SSO), centralized user Profile Management, consolidated billing, or the like.
If you do have multiple applications, and you need to leverage SSO, then we recommend you check out our How to Implement Single Sign-On training guidance before continuing.
The value of investing time on the landscape of the architecture up-front is something that we have found pays dividends in the long run, and there are a number of things you will want to consider when looking at functionality and workflow:
- What should the URL look like when Auth0 needs to present a web page to a user?
- How can Auth0 be structured to support your SDLC (Software Development Lifecycle)?
- How can you ensure that your Auth0 tenants are appropriately associated with your contract?
- What do you need to consider if there are other projects in your organization integrating with Auth0? Particularly projects that target their own, or a different domain of users (for example, applications that only employees will use)?
Organizations often service more than one domain of user - customers, employees, and affiliates being the most frequently encountered, with typically little to no cross-over: employees, say, don’t use the same applications as customers and vice-versa. In some cases there can also be a need to partition further within a domain - separate groups of customers, say, who use different and unconnected products. Auth0 provides a way to segregate your users and the associated collateral, and tenant provision covers this in more detail. If you need to provision an independent tenant then you’ll also want to associate this with your existing Auth0 account, so that you can take full advantage of the benefits provided at your organization’s contracted subscription level.
It’s not uncommon for companies to have identity requirements that address multiple user communities: customers, partners, employees, etc. So be sure to consider other projects or future requirements when designing your architecture.
In addition, you’ll undoubtedly have an established set of processes and procedures as part of your Software Development Lifecycle (SDLC). So you’ll want to check out our SDLC support guidance regarding Auth0 Tenant provision in support of that too.
For customer-facing applications, we typically see OpenID Connect (OIDC) as being the most frequently used protocol. OIDC makes use of web based workflows with browser URLs that are presented to the user. Out-of-the-box, client facing URLs as part of Auth0 OIDC support are Auth0 branded, however we recommend using the Auth0 custom domain capability to provide for consistent corporate identity and to also address potential user confidence concerns before they arise.
Other groups within your organization may also be working with Auth0; it’s not uncommon for our customers to have disparate departments that serve different user communities. Identifying these will potentially influence your design choices, and doing so early could mitigate decisions that might prove costly later on.
Get Started with Auth0 Video
Watch this short video Architecture: Your Tenant to learn what an Auth0 tenant is and how to configure it in the Auth0 Dashboard. Understand why you may want more than one tenant if you have different user communities, and also how you can use more than one tenant to support your Software Development Life Cycle (SDLC). Understand the importance of tenant naming and custom domain usage best practices. Also learn how to set up additional tenant administrators and how to associate tenants with your Auth0 account.
Everything starts with an Auth0 tenant. This is where you will be configuring your use of Auth0, and the where Auth0 assets - such as Applications, Connections and user profiles are defined, managed and stored. Access to an Auth0 tenant is performed via the Auth0 Dashboard, and via the Dashboard you can also create additional, associated tenants; you’re allowed to create more than one Auth0 tenant so that you can structure your tenants in a way that will isolate different domains of users and also support your Software Development Life Cycle (SDLC).
Determining the level of isolation you require when it comes to your user domains is an important step, and together with your branding requirements will subsequently help you determine the number of Auth0 tenants that will be required in your production environment. As we recommend you create a full suite of SDLC supporting tenants for every Auth0 tenant you will run in a production environment, the number of Auth0 tenants you will need to manage can quickly grow. Therefore you should consider carefully before creating multiple Auth0 tenants for production, and should consult our guidance on Branding before making your final decision.
To ensure that your tenants are all associated with your Auth0 contractual agreement and have the same features, ensure all your tenants are associated with your company account. If you have individual developers that want to create their own sandboxes for testing, make sure they get associated with your account so they have the same permissions too. To do this you should contact your Auth0 representative or the Auth0 Support Center at https://support.auth0.com.
When you setup your Auth0 tenant, the URL for accessing that tenant will be of the form
https://YOUR_TENANT.auth0.com. Providing a Custom Domain (also known as a vanity URL), for your Auth0 tenant is not only an important factor for supporting your Branding requirements, but more importantly will also provide you with security benefits too:
- Some browsers will, by default, make it difficult to communicate in an iFrame if you don't have a shared domain.
- It's harder to phish your domain if you have a vanity URL, as the phisher must also create a vanity URL to mimic yours. For example, with a custom domain you can use your own certificate to get an "Extended Validation", making phishing even harder.
Your custom domain name should also give the user confidence that this is the appropriate place to enter their credentials, and we recommend that you create your custom domain in all environments early on to ensure that you are testing consistently between environments. It's extremely important to train your users to to look for suspicious URLs when entering their credentials!
Create a custom domain (a.k.a.
CNAME) for your Auth0 tenant, and also create one in development too so you can ensure you have managed the
CNAME correctly. For example, you could create a
CNAME which maps
In almost all cases, customers have been most successful when adopting a strategy of a centralised domain for authentication across multiple product or service brands. This strategy provides users with a consistent UX, and also mitigates the complexity of deploying and maintaining multiple Auth0 tenants in a production environment. If you are considering having multiple domains for different brands, please refer to the Branding guidance before you begin implementing.
Every company has some form of Software Development Life Cycle (SDLC), and throughout the development process you will want to align with that strategy. For instance, you need to be able to test your integration with Auth0 in a similar fashion as you test the applications themselves. It is therefore important to structure Auth0 tenants to support your SDLC, and there is a consistent pattern which our customers typically follow when it comes to the best practices associated with tenant layout for doing so:
|Environment||Sample Tenant Name||Description|
|Development||company-dev||A shared environment where most of your development work occurs|
|QA/Testing||company-qa or company-uat||An environment for formal testing of the changes you've made|
|Production||company-prod||The production tenant|
In some cases you may also want to create one or more sandboxes (e.g., company-sandbox1, company-sandbox2) so that you can test changes without compromising your development environment. This might be where you test deployment scripts and the like.
