Social media integration: Auth0 supports over 30 social logins with support for the major ones such as Facebook, Twitter and Google. Besides the 30 or so out-of-the-box providers, Auth0 also allows custom social connections through their extensions framework. This to me provides a great amount of flexibility to solution architects.
Ready-to-use modern APIs using JSON/RESTfull
LDAP integration
It enables the concept of identity management.
The feature improvement I would like to see in Auth0 is around authorization. They can borrow Stormpath's (their primary competitor) notion of groups and organizations built-in on their API. Currently Auth0 takes a different approach, i.e., it uses rules to store authorization-related info on the metadata.
I have used it for nine months.
I have not encountered any stability issues.
I did encounter a scalability issue. Auth0 support engineer could have been more descriptive on the infra needs for the on-premise installation. The solution had only one MongoDB instance, which became a single point of failure. Once we hit the bottleneck, the Auth0 team was prompt enough to set up a master-slave structure to fix the issue. They could have thought about it up front.
Level of technical support - 7/10. They keep changing the support engineers (shared resource pool). Every time a new engineer comes, we have to give him/her the complete background before he/she becomes productive.
I did not previously use a different solution.
It is very easy to use the public cloud instance.
Before choosing this product, I also evaluated Stormpath.
Be specific about the number of users, number of transactions, and the amount of data to be transferred.
