Shared insights

As our most active customers needed to remember five different username-password combinations to use our services, it became painfully clear we needed a single sign on system. We looked at a few different systems, but Auth0 allowed us to use a single system for all our B2C, B2B and B2E requirements, had very reasonable pricing and provided a great deal of flexibility thanks to its use of Rules, Hooks, Extensions and Hosted Pages.

You can use any combination of identity providers, without having to make any changes to your app. You can even enable a different set of providers for different applications. We use passwordless, social and database login and plan to add Active Directory soon too.

Integrating Auth0 is incredibly easy, fast and flexible. With just a few lines of code, you're up and running, no matter if you need OAuth2, OpenID Connect or SAML. It provides great quick starts, clear documentation and quick support, both through the community forum and support desk. We're currently running it with various Node.js, PHP and Ruby applications.

All in all, Auth0 provides us with a common user identity across our applications and allows us to focus on the features of our applications, instead of having to spend hours and hours on creating safe login systems.

I use Auth0 because we have multiple projects which were using their own db to authenticate users. After the introduction of GDPR ( we decided to provide SSO functionality to users by maintaining the data at centralized place and for that we have multiple options but Auth0 was the best one in every aspect. So we decided to go with Auth0 and now almost after one year we have successfully exported all of our users in Auth0. Auth0 also has great functionality of configuring social providers like facebook, twitter etc and enterprise connections like Active Directory which is very beneficial. Also it maintains all the logs which is very useful. Overall I would say Auth0 is great in every aspect. It contains all the functionality that I required and Auth0 support team is great and very cooperative. They always respond within a day which is a great thing. Last thing Auth0 community is also another place where we can share our knowledge. It still requires some efforts to become a competitor of big communities like stack overflow and github but the way Auth0 is working, I hope it won't take very long to reach at that level. So in last I wish Auth0 best of luck.

I chose Auth0 because of the simplicity of integration into my current infrastructure. It brings a lot of value with minimal effort and minimal costs. I have used it on .net, angular, vue, node, firebase and many other applications. It is one of the essential tools on all my projects now.

We use Auth0 because it allows us to focus on the business logic of our product and not the "distracting" process of authentication and session management.

Another factor is that authentication and security is of the utmost importance for us so we wanted a solution that this is their main concern.

I use Auth0 because it is very good to integrate social login providers easily and the learning curve is very less to implement Auth0.

PS: Open to exploring options of going completely native ( AWS Lambda, AWS Security but have to learn all)
