Identity workflows have transformed how we secure logins and manage user access daily
There are different elements to the best features Auth0 Platform offers, and I have touched on them, particularly the ability to help applications authenticate and authorize their users and manage their identities. A big point is identity federation, allowing connections across multiple identity providers, enabling users to log in using existing accounts due to databases and enterprise identity systems. A strong security feature is provided, particularly with their MFA, multi-factor authentication, which includes bot detection and brute-force protection, along with breached password detection, which is really good as an added extra. Auth0 Platform has positively impacted our organization, particularly in terms of usability. While we are not selling it directly, I find the platform easy to use for authenticating different users. Our own services team handles the implementation, so I cannot comment on the ease of that process. However, whenever we have had contracts and bids to roll out services, it has been really easy. We have seen improved security due to the implementation of Auth0 Platform. User management, such as creating and deleting users, is all about enhancing the user experience, which is massive. We assist with password resets and account linking. The time to implement is shorter, and we maintain a consistent user experience with a secure login flow, benefiting from a faster implementation due to the universal login, providing a hosted login page customizable by developers.

Gluu has a mobile app catering to field workers. Normal workers use the web app, a complete cloud-based solution. They log in on any device and access the system. Gluu filters and displays relevant information based on the user's role in the processes. Users can set it up to view as a viewer, worker, manager, or controller of the area. The front end offers different views but provides an easy dashboard for employees. On the dashboard, users can configure it to show tasks, related work instructions, and connected processes. It's very user-friendly, allowing end-users to understand their tasks and processes without needing in-depth knowledge.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's a very powerful platform. It has the ability to do the usual stuff, according to modern protocols, like OIDC and OAuth 2. But the real benefit of using the platform comes from its flexibility to enhance it with rules and, now, with what they call authentication pipelines. That is the most significant feature, as it allows you to customize everything regarding the authentication and authorization process."
"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)."
"If we had to develop our own and manage it, it would take years of development and maintenance. In those terms, it’s definitely beneficial."
"Auth0 Platform is effective for businesses looking to simplify authentication and identity management, and I would strongly recommend it."
"Auth0 Platform is especially helpful if you are dealing with a customer-facing application."
"What attracted me to Auth0 Platform is how simple and easy it is to implement with my applications."
"After migrating to Auth0 from a custom authentication system, we noticed substantial improvements in developer productivity, auth-related implementations, and reduced login flow flaky tests."
"Auth0 supports over 30 social logins with support for the major ones such as Facebook, Twitter and Google, and also allows custom social connections through their extensions framework, which provides a great amount of flexibility to solution architects."
"Gluu has a mobile app catering to field workers. Normal workers use the web app, a complete cloud-based solution. They log in on any device and access the system."
"Most of the features are related to banking within this particular IT industry. Security and the market are also important features."
 

Cons

"Even now, it is a pain to back up to an offline location or it is hard to back up everything to your own data center or your own location."
"In the past, there was an issue with the multi-tenant where there wasn't the ability to manage them."
"As your user base grows, Auth0 Platform pricing can become a concern in an enterprise context."
"Auth0 Platform could improve by allowing more than three enterprise connections, as I remember it being three."
"The reporting in Auth0 Platform could use improvement."
"The product support for multi-tenancy could be improved."
"Regarding improvements for Auth0 Platform, during the last time I used it, I observed that during log analysis or when using the search or filter options, I missed some features."
"Auth0 Platform works pretty well, but ways it can be improved include the universally cited complaint that the free tier is generous, but the jump to paid can be steep for a growing startup."
"I would like to see features around federation, authentication, authorization, and AI APIs with a ChatGPT interface."
"The tool integrates AI into the process modeling aspect. I believe this addition will significantly enhance usability. Additionally, it might be beneficial to have the capability to import content from other tools into this platform. Our platform follows its business process modeling notation standard, which differs from BPM. It uses a simpler notation, making it easier. The ability to import content from other tools could accommodate users accustomed to different standards."
 

Pricing and Cost Advice

"Pricing of Auth0 is a pain point. Their pricing model is very confusing, at least for an enterprise. I don't like their pricing model. I think it's too aggressive. It's not very cheap for a service that only does authentication."
"There are different price levels: B2B, B2C, and enterprise. The basic plan is about $1,500 per month."
"I am pretty happy with the pricing model of Auth0. It is very clear for me. Considering our scale, the features that we are using, and additional features that we bought, we still find it great. If you split the costs for the whole year and calculate the number of people you needed to hire, it always comes out to be much lesser than what we would have spent on building our own solution."
"The tool is cheaper compared to competing solutions. Those alternatives tended to be more expensive. Consequently, Okta purchased it because it was considerably cheaper. The solution even offered some free services while still providing excellent functionality."
"It is a relatively inexpensive product in the industry."
"The tool is cheaper compared to typical German products. I rate the product’s pricing a four out of ten."
"The price is reasonable."
