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.

FusionAuth offers several valuable features that stand out to me: control, development flexibility, deployment flexibility, and extensibility. Unlike competitors, it allows me to host it anywhere. I can deploy locally via Docker or on Kubernetes, so I am using a hybrid approach. Another valuable feature is that there is no cap on scaling. Many CIAM providers use a pricing model that starts cheap and then spikes drastically based on monthly active users, but FusionAuth's pricing does not penalize growth—you pay on feature, not per user. The deployment flexibility has helped my team from an engineering perspective and directly solves some of our biggest infrastructure challenges. If an enterprise client requires all their auth data to remain within a specific AWS region, we can support that without changing our application code. FusionAuth has positively impacted my organization by providing significant engineering cost savings. Building and maintaining a secure, compliant authentication system is difficult and requires a dedicated engineering team. This solution helps us with both time savings and cost savings since we are a fast-paced startup. Additionally, it has led to improvement in developer velocity, as when authentication is decoupled, our development teams can ship features significantly faster while meeting strict enterprise compliance. Regarding specific outcomes or metrics, I can say our developer velocity has nearly doubled, as our engineering focuses more on developing features rather than dedicating resources to authentication systems. In terms of financial impact, there has been a 150% improvement.

Quotes from Members

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

Pros

"Auth0 Platform gave everyone a single, consistent way to handle authentication and authorization across our organization, which reduced bugs, made code reviews easier, and made onboarding new developers much faster because they only had to learn one auth system."
"Auth0 Platform is effective for businesses looking to simplify authentication and identity management, and I would strongly recommend it."
"It is easily connected and easy to put our app in single sign-on."
"We use this solution for authentication and authorization, and we deploy it on cloud, where it supports identity federation, FSO and multi-tenancy."
"Thanks to Auth0 Platform, we are ISO 27001 certified."
"This solution does what we want it to do."
"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."
"There have been many improvements in our cloud technology since we are using Auth0 Platform, and it reduces our development time while providing many features to integrate and utilize so that everything is available in one place and we can develop our application faster, which minimizes our time and maximizes utilization."
"Regarding specific outcomes or metrics, I can say our developer velocity has nearly doubled, as our engineering focuses more on developing features rather than dedicating resources to authentication systems."
 

Cons

"Better documentation for Salesforce integration is suggested."
"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 is not as flexible compared to ForgeRock or IBM Security Access Manager."
"One of the sought features in our company that we would like Auth0 Platform to improve is the adoption of new features and how quickly they are integrated."
"The tool's price should be improved."
"The pricing should be lower. A reduction of 20-25% would be great."
"The Management API could be improved so it's easier to get user information."
"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."
"FusionAuth could improve its UI customization for the admin console and enhance the documentation to make it more user-friendly."
 

Pricing and Cost Advice

"There are different price levels: B2B, B2C, and enterprise. The basic plan is about $1,500 per month."
"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."
"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."
