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

"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."
"Auth0 Platform has been working as expected, and we only need to scale our system."
"The most important feature for me was the ease of use, as it needed to be easy to integrate into my platform."
"When comparing Auth0 Platform with Azure, you have to do a lot of things yourself if you want it to work and look and feel in a certain way, but with Auth0 Platform, that comes more out of the box."
"The most important feature for me was the ease of use, as it needed to be easy to integrate into my platform."
"Auth0 Platform's best features include automating the entire login stream in a secure way, providing storage for user credentials, offering a robust password reset facility that users can use by themselves without involving any of my support personnel, and providing a log of all user interactions in terms of logins, logouts, and password resets."
"The best features of Auth0 Platform are that it is easy to integrate and is cross-platform, as we use it with the Angular front end, the UWP application, and the iOS application, and it is really easy to integrate within the dashboard without any complications."
"It has improved our organization by providing login authentication for a mobile app."
"Most of the features are related to banking within this particular IT industry. Security and the market are also important features."
"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."
 

Cons

"In the past, there was an issue with the multi-tenant where there wasn't the ability to manage them."
"This is a costly solution and the price of it should be reduced."
"I find it surprising that there is no access to a standard user profile."
"There is a possibility to improve the machine-to-machine authentication flow. This part of Auth0 is not really well documented, and we could really gain some additional knowledge on that."
"This is a costly solution and the price of it should be reduced."
"There could be easy integration with IoT devices for the product."
"The reporting in Auth0 Platform could use improvement."
"In my previous experience a couple of months ago, I checked and the permissions assigned to the user were not working, but then I had to update it by going to its company and then providing the particular permissions."
"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."
"I would like to see features around federation, authentication, authorization, and AI APIs with a ChatGPT interface."
 

Pricing and Cost Advice

"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."
"It is a relatively inexpensive product in the industry."
"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."
"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."
"The price is reasonable."
"The tool is cheaper compared to typical German products. I rate the product’s pricing a four out of ten."
