What do you like best about the product?
Have been using FusionAuth as our primary identity provider for a few years now. It's been fantastic. Their documentation is professionally written and well organized - that along with their "Ask AI" feature has made it possible to accomplish some sophisticated configurations to meet our customer needs without having to reach out needlessly for support. Speaking of support... they are very friendly and quick to respond to messages. Various installation methods (managed or self-hosted) and different plan tiers make it quite flexible for various product needs. The starter plan is very generous and compared to other offerings on the market the cost is minimal. Overall I'm very pleased with selecting FusionAuth as our identity provider.
What do you dislike about the product?
Minor gripe, but I would find it helpful to be able to generate more advanced reports on users, usage, sessions, etc from the dashboard directly. Some of the reports I've had to generate in the past were easier to generate by using their API, then writing a quick script to roll-up results. Otherwise, not much to "dislike" about the service - it's frankly been one of the easiest to incorporate into our stack. Very pleased with our decision.
What problems is the product solving and how is that benefiting you?
We needed an affordable way to implement multi-tenancy in a B2B scenario, are were particularly interested in the "Identity Provider" support so we could offer customized SSO for each tenant individually. Achieving this with competitors would be possible, but at significant cost. The primary benefit to FusionAuth for our team has been the ability to fully isolate tenants and configure them to meet varying customer needs. Furthermore, their API has made it possible to automate much of the provisioning and deprovisioning of tenants, users, and other bits of configuration.

What do you like best about the product?
What we truly like is that it is quite seamless to utilise several separate client environments with only a single FusionAuth instance. The flexibility of the theming of our online onboarding process of new B2B customers has allowed us to add a branded login experience without any glitches. We also found the custom data fields so helpful in assigning specific fields of data to user profiles, in order to drive some of our internal analytics.
What do you dislike about the product?
The configuration settings that are not used often, at times, are a little less transparent to navigate the console. We also would have liked to see an easier way to export/import whole application setups between our development and production servers. There was also a steep learning curve to using some of the advanced webhook event triggers, although this got easier as time went on.
What problems is the product solving and how is that benefiting you?
We found it very difficult to offer different branded identity experiences to each of our B2B clients, and then have a single user database. Previously to FusionAuth it could take weeks of custom development to implement a new customer inviting them to use a customized portal into their company and managing their user account. Once, it takes weeks to spin up a new client tenant with its own branding, and user roles, now it only takes a matter of hours. It has turned onboarding client workflows into a fast repeatable procedure.

What do you like best about the product?
What I like most about FusionAuth is its flexibility. It’s really intuitive to set up. I’m not a full-time developer, but I’m pretty sure I can configure logins, SSO, and integrations in a much easier way without spending days reading documentation. Fine-grained customization allowed me to form the login experience around my company’s brand perfectly, a process that other avenues made extremely cumbersome. It feels like the control is with me and not that I require external consultants.
What do you dislike about the product?
The main drawback is the learning curve once you want to go beyond the basics. Some of the more advanced workflows, such as complex triggers or esoteric identity provider integrations, take a bit of trial and error. Also, while being more approachably priced than Auth0, the add-ons can add up if you’re not careful.
What problems is the product solving and how is that benefiting you?
Earlier, we were trying to patch homegrown login systems together with each other as well as with third-party solutions that didn’t speak to each other. This was creating these huge security holes as well as friction for the user. Every one of our sales, support, and engineering teams use the same platform to authenticate and track their interactions.

What do you like best about the product?
The flexibility and developer-friendliness are my favorite things about FusionAuth. It can be a real challenge to configure multi-step authentication processes when you’re not a full-stack security engineer; however, it is enough to get it done in a few simple tweaks due to the existing functionality and lucid documentation. I hardly ever need anything that’s not already onboard, but if I do, the API is robust enough to not struggle to hammer it into other systems.
What do you dislike about the product?
Indeed, the depth of the system might be overwhelming for a novice, and it will take some time to get accustomed to the functionality before all settings are configured properly. Comparing it with Auth0 or Okta, it is reasonably priced, though some advanced enterprise features may feel expensive for a micro-enterprise. More so, file limits concerning logs, and event data may also prove a limitation in case you would want to archive an extensive history.
What problems is the product solving and how is that benefiting you?
FusionAuth centralized identity and access management so there are no more scattered authentication systems for different applications. We’ve reduced our risks by using fine-grained role and permission settings and the integration of our external systems means less time building one-off login solutions. Provisioning real-time insights into user activity enhances accountability while avoiding repetitive provisioning tasks for my team due to the automation of most workflows by this system.

What do you like best about the product?
It gives me full control over user management without forcing me into a specific workflow. The documentation is clear and the admin dashboard is easy to navigate. I like that it supports multiple authentication methods like OAuth, SAML, and passwordless so I can adapt it for different clients.
What do you dislike about the product?
The initial setup takes some patience especially if you are hosting it yourself. Some advanced configurations feel a bit buried in the settings.
What problems is the product solving and how is that benefiting you?
I needed a way to handle logins and registrations securely across multiple apps without building everything from scratch. FusionAuth let me plug in robust authentication quickly while keeping user data safe. It’s saved me a lot of development time and reduced maintenance headaches.
