We use the solution for B2C connection between our customers on the mobile web.
Solutions Architect III at Raizen
An excellent solution for B2C connection between our customers with an easy setup
Pros and Cons
- "It is easily connected and easy to put our app in single sign-on."
- "The price modelling is a bit confusing on the site and can be costly."
What is our primary use case?
How has it helped my organization?
It is easily connected and easy to put our app in single sign-on. For example, Auth0 is easy to bring connections for mobile devices and has good documentation.
What needs improvement?
Today we use home basic authentication and authorization, and we would like to move away from cloud and use some kind of IDP to improve authentication and authorization for our customers. So, for example, we can use the social logging feature in Auth0 to improve the customer experience.
The price modelling is a bit confusing on the site and can be costly. So if you use one measure like active user format, you need to talk to the support from Auth0 to check the price.
For how long have I used the solution?
We have been using this solution for about two months. We are using the latest version. It is currently deployed on private cloud.

872,655 professionals have used our research since 2012.
What do I think about the stability of the solution?
It is stable according to the documentation and support we have from Auth0. I rate the stability a ten out of ten.
What do I think about the scalability of the solution?
We have 50 users using Auth0 and plan to increase the number of customers.
How are customer service and support?
I rate the technical support a ten out of ten. It is very good.
How was the initial setup?
The initial setup was easy, and I rate it a ten out of ten. Our company uses Terraform to build up infrastructure from AWS, and we used a partner to build the product. We needed around five people for deployment, and they were mainly engineers and senior developers.
What's my experience with pricing, setup cost, and licensing?
The pricing is very high, so I rate it a four out of ten. To be in auto-production, we need other add-ons and extras that can be used for motor factory authentication. So for our product, we need to have multifactor authentication and pay for it.
What other advice do I have?
I rate this solution a ten out of ten. I recommend architects and engineers check and verify how many users they need for some time, like a month, six months or even a year. With this approach, you can check the price and costs from Auth0 support and try to balance the costs and features we would like to have.

Software Engineer at Streams Tech, Inc.
Provides interface application integration, but Management API needs to be improved
Pros and Cons
- "The most valuable feature is interface application integration, but we haven't fully used it yet. We'll need it in the future for a few potential clients."
- "The Management API could be improved so it's easier to get user information."
What is our primary use case?
Our initial use case was authentication. We didn't want to implement anything from scratch, so we needed an out-of-the-box solution. That's why we chose Auth0.
Right now, it's deployed on-premises for our development environment and on cloud. The cloud provider is AWS.
We're in the beginning stages of a project, so only 10 people are currently using this solution in my organization.
What is most valuable?
Currently, we're just using the login and sign-up features. The most valuable feature is interface application integration, but we haven't fully used it yet. We'll need it in the future for a few potential clients.
What needs improvement?
The Management API could be improved so it's easier to get user information.
For how long have I used the solution?
I've been using Auth0 for three months.
What do I think about the stability of the solution?
The solution is stable.
What do I think about the scalability of the solution?
I've had a few problems with the scalability, but it's okay overall.
How was the initial setup?
Initial setup is easy. Deployment took less than an hour.
What's my experience with pricing, setup cost, and licensing?
There are different price levels: B2B, B2C, and enterprise.
The basic plan is about $1,500 per month.
The basic plan is good for our requirements. In the future, we might get the enterprise plan.
I think Auth0 is worth the cost.
What other advice do I have?
I would rate this solution as six out of ten.
There are a few small problems, like with Management API. For integration purposes, it's easy to use. The solution is good for starting projects and for startups. There are a few other options for out-of-the-box solutions, like AWS or Azure AD, but we chose Auth0.
Which deployment model are you using for this solution?
Hybrid Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

Platform Engineer - Linux at a tech services company with 201-500 employees
Easy and flexible integration regardless of the codebase
Pros and Cons
- "The most valuable feature is that it is simple to integrate, irrespective of your codebase."
- "This is a costly solution and the price of it should be reduced."
What is our primary use case?
We were evaluating Auth0 as centralized authentication solution for our in-house development. We are searching for the best solution to take care of this because our product development is ongoing, and we want to find just the right fit. Ultimately, we did not choose Auth0.
What is most valuable?
The most valuable feature is that it is simple to integrate, irrespective of your codebase.
What needs improvement?
This is a costly solution and the price of it should be reduced.
For how long have I used the solution?
We had been evaluating and testing Auth0 for between three and four months.
What do I think about the stability of the solution?
It is pretty much stable. We did not encounter any issues with respect to integration and testing.
What do I think about the scalability of the solution?
Considering we are conducting a PoC, we are not able to fully test scalability. However, our understanding is that it scales well.
How are customer service and technical support?
My team was in touch with their counterparts from marketing and technical resources, but because it was a PoC engagement, we did not take it further.
Which solution did I use previously and why did I switch?
We did not use another SSO product before our current PoC began.
Which other solutions did I evaluate?
We have been evaluating multiple single sign-on solutions including Auth0 and Okta.
We run a successful proof of concept but we did not select Auth0 because their entire structure is hosted on AWS, and we are a data center company so we thought that having the backend hosted on AWS was not the right choice for us.
Had this same solution been available as a private deployment then it would have been the right fit for us.
What other advice do I have?
During our exploration and evaluation, Auth0 and Okta were the top contenders from a pure authentication point. My advice for anybody who is considering such a system is to have multiple authentication systems evaluated from a technical point of view, and adopt the one which rightly suits your use case and requirements. Different products have different features sets, but what matters most is that it is purely compatible with your use case. Scalability is probably the most crucial factor.
I would rate this solution an eight out of ten.
Which deployment model are you using for this solution?
Public Cloud

Security Architect at a construction company with 10,001+ employees
Provides login authentication for mobile apps and has good stability
Pros and Cons
- "It has improved our organization by providing login authentication for a mobile app."
- "The product could use a more flexible administration structure"
What is our primary use case?
I'm a security architect. The product is used by our customers, not by our company people directly, so I expect we would have several thousand people using this solution.
How has it helped my organization?
It has improved our organization by providing login authentication for a mobile app.
What is most valuable?
The most valuable feature would have to be authentication using OpenID Connect.
What needs improvement?
The product could use a more flexible administration structure in the next release. It could be improved by extending the administration model.
For how long have I used the solution?
I've been using Auth0 for about two years.
What do I think about the stability of the solution?
There is no problem with product stability.
What do I think about the scalability of the solution?
We haven't had any problems with scalability.
How are customer service and technical support?
We've had good experience with technical support.
Which solution did I use previously and why did I switch?
We previously used a different solution which was an open-source solution that was on-prem. I can't recall the name of that, but it was an open-source tool. One of the main reasons we switched to Auth0 is that supporting an on-prem version required a certain amount of expertise and management and we didn't need to be spending money on that if we were using a software as a service provider.
The other aspect was that on-prem you have to manage the security yourself. By using a software product as a service provider in the cloud, we were able to outsource those security concerns to them. The security was their responsibility and no longer our problem.
How was the initial setup?
The setup is straightforward. We've deployed it in a number of applications, some of those would have taken less than a couple of days of development and deployment, and some of them would have taken weeks. But it's dependent on the complexity of the deployment. That's not a function of Auth0, it's a function of what our digital transformation is trying to do. We used an Auth0 consultant for deployment.
What about the implementation team?
We used an Auth0 consultant for implementation and he was very good and very knowledgeable. There is nobody in our company dedicated to maintaining the system for our customers.
What's my experience with pricing, setup cost, and licensing?
There are licensing costs for this product. We have an enterprise agreement with Auth0.
Which other solutions did I evaluate?
We evaluated a couple of other options before choosing Auth0. We looked at Microsoft and Okta. We went with Auth0 because at the time Microsoft was about to renew, so it wasn't as easy to set up, although Microsoft is a fine product and Okta is also a fine product, at that stage, it was more aligned on-prem authentication than it was to B2C.
What other advice do I have?
In terms of advice, I think that if your application is developer-driven, then Auth0 provides extremely good developer support and supports multiple development tools and strategies. That's where I believe the product comes into its own. If you're enterprise, then Okta or Microsoft are probably a better solution. It's worth watching.
I would rate this product an eight out of 10.

Security Architect at a construction company with 10,001+ employees
Secure, developer-friendly, and the support is good
Pros and Cons
- "The valuable features are that it is extremely secure and that it's developer-friendly."
- "In the past, there was an issue with the multi-tenant where there wasn't the ability to manage them."
What is our primary use case?
The primary use case of this solution is to authenticate APIs, customer authentication, and business-to-business authentication.
What is most valuable?
The valuable features are that it is extremely secure and that it's developer-friendly.
What needs improvement?
In the past, there was an issue with the multi-tenant where there wasn't the ability to manage them. For example, if you have three tenants you couldn't have different managers, but that has been sorted out through the release tool.
For how long have I used the solution?
I have been using Auth0 for three years.
What do I think about the stability of the solution?
This solution is stable, we have not had any issues.
What do I think about the scalability of the solution?
It's a scalable product.
How are customer service and technical support?
We have contacted technical support and find that they are good.
How was the initial setup?
The initial setup of the solution was simple, but our requirements were complex.
The deployment time varied depending on the complexity. Some would have taken a week while others would have taken three months.
What about the implementation team?
We used external consultants and consultants through Auth0 to help with the implementation.
What other advice do I have?
This solution does what we want it to do. It's good and I don't see any issues.
For anyone wanting to use this solution, make sure that your developers are fully engaged. They have to know how Auth0 works and what the best way to leverage it.
I would rate this solution an eight out of ten.

Manager at IDAZCO
It's more efficient than regular session management through a database because I only request profile data when needed.
Pros and Cons
- "I simply use the JWT from the client on the server side to process requests and push updated profile data to a database/queue as needed and end the process without having to persist data in the web server (sessions)."
- "I think they can do a better job in explaining what you're supposed to do next in order to correctly follow an idiomatic approach to using the solution beyond simply passing a JWT token to a server and having the server check then signature to validate the token."
What is most valuable?
I implemented the use of authentication workflow entirely on the client side (S.P.A./Single Page Application). This gives the client app a JWT and makes the infrastructure a lot easier to manage in a distributed way since I don't need to track user sessions on the servers anymore. Now, I simply use the JWT from the client on the server side to process requests and push updated profile data to a database/queue as needed and end the process without having to persist data in the web server (sessions).
How has it helped my organization?
We are now able to dockerize stateless containers quote easily. A typical solution for managing session data is to put it into a database, but now we don't need to do that either. Auth0 essentially acts as the database backend. However, unlike regular session management through a database, whereby one needs to touch the database every time to re-hydrate session data for every request, I only make requests to Auth0 to query for profile data when needed, thus making the application more efficient.
What needs improvement?
The documentation and getting started guide is excellent for JWT and client-side authentication. However, I think they can do a better job in explaining what you're supposed to do next in order to correctly follow an idiomatic approach to using the solution beyond simply passing a JWT token to a server and having the server check then signature to validate the token.
For how long have I used the solution?
I've just started using it.
What was my experience with deployment of the solution?
No issues encountered.
Which solution did I use previously and why did I switch?
We used regular OAuth in conjunction with our own database for people without social accounts. This is much better because everything is wrapped and normalized through one service. It even supports non-OAuth solutions such as Active Directory and LDAP which is good.
How was the initial setup?
It was extremely simple and their site even generates sample code in various languages.

Update: Auth0 just announced a FREE plan that allows for up to 7000 monthly users. There are limitations, such as allowing for just 2 OAuth providers ... but for development purposes that's not a big deal IMHO. Check out the details here: bit.ly
On the down-side, they don't offer a reasonable pricing structure for solution providers who service small businesses that require Enterprise connections (AD / LDAP etc). In that area their pricing is aimed more toward singular .. large corporations.
