Intuitive, Secure, and Developer-Friendly, But Pricey
What do you like best about the product?
I love the developer experience with Auth0 and how quickly I can get user authentication running. The good documentation and SDKs make complex tasks like JWT Token management for my websocket chat interface straightforward. The developer experience helps me tremendously because the clear documentation for code examples with Python/FastAPI means I can integrate authentication into my backend API endpoints easily. Also, the initial setup was quite easy, and the helpful guide made the process smooth.
What do you dislike about the product?
The main problem I face is the price structure can get quite steep as my user base increases. Especially with features like MFA and advanced security that should arguably be standard for an app handling voice recordings.
What problems is the product solving and how is that benefiting you?
I use Auth0 for secure user authorization, which eliminates the complexity and security risks of building an authentication system from scratch. The developer experience with clear documentation and SDKs helps me integrate authentication into my backend API endpoints easily.
Auth0 takes the complexity out of authentication so I can focus on building rail software
What do you like best about the product?
In my day-to-day work as a backend developer at Sternico, I really appreciate how Auth0 removes a whole category of problems from my plate. I work a lot with C#, ASP.NET Core, REST APIs, and Onion Architecture, and integrating Auth0 into that stack has been surprisingly smooth. Their SDKs and documentation fit naturally into the .NET ecosystem, and features like MFA, passwordless options, and role-based access are basically ready to go. I no longer have to write or maintain piles of custom authentication code, which is a huge relief, especially in a domain like railway operations where security and reliability matter a lot. It lets me stay focused on building solid business logic instead of messing around with token lifecycles every week.
What do you dislike about the product?
Pricing model isn’t always easy to predict. Some important features only pop up in higher tiers, which can be a challenge when planning long-term usage across multiple applications.
What problems is the product solving and how is that benefiting you?
At Sternico, a lot of what we build, whether for RAILBASE, COMAP, or custom integrations, depends on secure, reliable access control. Auth0 helps us deliver that without reinventing the wheel. For me personally, it shortens development cycles since I can plug secure authentication into our .NET Core services and APIs quickly. It also supports our broader architecture: cleaner separation of concerns, better maintainability, and fewer custom security components to maintain over time. Since we work in the railway sector where safety, compliance, and traceability are crucial, having a stable identity layer gives us confidence and helps us release features faster without compromising on security. Overall, Auth0 fits well into our software ecosystem and supports the way our agile teams work.
Secure API access for enterprises has improved and provides dynamic authentication for users
What is our primary use case?
My main use case for Auth0 is for authentication purposes for my APIs. I rely on it mainly to give specific access to a specific enterprise or user depending on their eligibility.
I use Auth0 to authenticate our enterprise customers before giving them access to a set of APIs where we show them the data or billing information, anything that they want and we can offer. Everything goes through Auth0.
What is most valuable?
The best features Auth0 offers are its scalability and it is a better way of authenticating a user compared to just a tokenized version of authentication where the token is static and does not offer dynamic authentication compared to how Auth0 offers it.
While working in a dynamic environment where there are many enterprises involved in the service, you need a tool that can authenticate them on the go, which is why I like it.
Auth0 has positively impacted my organization. Previously we used the tokenized version of authentication. The work was simple, but when you push this code to deployment and enterprises are involved, it makes much more sense to authenticate them through Auth0 so that you can just get a login for yourself when you are authenticated, which helps to dynamically scale depending on the product and its viability.
The specific outcomes since I started using Auth0 include time-saving, more security, and scalability, which are the three things I would emphasize.
What needs improvement?
I do not think there are any improvements needed for Auth0, other than maybe making it more visible to beginners. Auth0 could be made more accessible to beginners.
For how long have I used the solution?
I have been using Auth0 for almost three years.
What other advice do I have?
The features of Auth0 have been thoroughly covered. I would rate Auth0 an eight out of ten. I chose eight out of ten because there is always something to improve in a product, and giving eight actually keeps that room for improvement compared to giving it a ten.
Auth0 is deployed in my organization as a hybrid cloud. We use Amazon Web Services as our cloud provider for the hybrid deployment of Auth0. We purchased Auth0 through the AWS Marketplace.
I would say to others looking into using Auth0 that if you are building any product which needs an authentication flow for your API-based approach, using Auth0 from day one might be very helpful because you can scale over it as quickly as possible. My overall rating for Auth0 is eight out of ten.
Outstanding User Management and Configuration Features

Now there is no need of building and maintaining that myself, i can now rely on their systems, that saves a lot of time and reduce the risks of messing up related to security.
Simplified Client Management with Auth0's Tenant Feature
What do you like best about the product?
I love using Auth0 because it simplifies the complex task of managing individual client tenants. With a large number of clients, manually handling each tenant could become chaotic, but Auth0 streamlines this process beautifully. The ability to break clients into tenants makes the management of different client environments much easier. This not only helps in organizing client data efficiently but also reduces the potential for errors. Additionally, the effectiveness of Auth0 becomes apparent when deploying our HR applications across multiple clients; each client can seamlessly authenticate into their respective environments. Despite the initial setup requiring some work due to the numerous options and requirements, once configured, Auth0 performs exceptionally well, providing an outstanding experience. This transforms what could be an overwhelming task into a manageable, smoothly-running operation.
What do you dislike about the product?
Setting up Auth0 requires significant effort and is not a straightforward 'click to setup' process. It demands time and understanding to fill in various options and requirements.
What problems is the product solving and how is that benefiting you?
I use Auth0 to manage client authentications efficiently by breaking clients into tenants, making it easier to handle multiple environments for deployment.
