"Flexible, Industrial Strength Auth for reasonable Rates"
What do you like best about FusionAuth?

It provided a good replacement for Auth0 / Okta for our system as we have been priced out of their "base market". It respects all of the same industry standards and complies with all necessary pieces but provides a bit more configuration capabilties and their docs are more focused on the development community as opposed to market "fluff". Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

Very minor in terms of "dislike" but it requires a lot more configuration to "get going" as opposed to the higher priced options. A higher level executive / manager probably would be put off, but teams implementing loved the options. Review collected by and hosted on G2.com.

"Flexible authentication and authorization platform with excellent support and great documentation"
What do you like best about FusionAuth?

FusionAuth documentation is great. Authentication is a complex subject but you will quickly gain a good level of understanding of how to implement FusionAuth in your stack with the way their documentation is structured.

Their support is excellent. In fact, I think it's the best support we have accross all our third parties. Yes we pay for the 24/7 support, but the fact remains that they take the time to actually understand our issues and go over potential solutions with meaningful suggestions be it via chat or video calls.

FusionAuth API is robust and well made. Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

The FusionAuth admin dashboard is not great for troubleshooting and monitoring users.

We needed to build a lot of internal tooling with their API to meet our needs. On the other hand, their product needs to be generic enough to cover most use cases and flexible enough (through their API) to cover more complex scenarios. However, I still feel like the dashboard could offer more information regading user sessions and user tracking (tokens issued, information added in these tokens, etc).

"Easy authentication management for thousands of system users"
What do you like best about FusionAuth?

Having the option for FusionAuth to host our solution in a single-tenant format giving us total confidence in uptime and availability. Add to that integrating robust security features with easy, out-of-the-box solutions like MFA and SSO. Implementing was well supported and fairly straight-forward - on the essentials plan we had helpful support on the timeline we agreed to. In our migration of 10,000+ users they never missed a beat with the just-in-time migration option keeping our solution online throughout. Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

There is a wide gap in support levels between the Enterprise and Essentials tiers of the service and we would have loved a more middling option with quicker guaranteed turnaround during business hours but not requiring 24/7 access to support. Otherwise our experience so far has been very positive. Review collected by and hosted on G2.com.

"FusionAuth is a great solution for developers needing identity management system."
What do you like best about FusionAuth?

FusionAuth supports multiple authentication protocols (OAuth, OpenID Connect, SAML), making it versatile for various application needs. Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

For those new to identity management, the range of features and configurations can feel overwhelming. A more streamlined onboarding process could help. Review collected by and hosted on G2.com.

Response from Brad McCarty of FusionAuth

Thanks for your kind words, Aakanksha! We're always looking at ways to improve our user experience. I'll pass your thoughts along to the Dev team.

"Good documentation"
What do you like best about FusionAuth?

This is a great auth ecosystem, though it requires becoming familiar with their installation and setup configuration / documentation to get started. Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

Not as clear directions for using a stock docker image how to setup the environment variables fully. Review collected by and hosted on G2.com.

"The product is good, the team is great"
What do you like best about FusionAuth?

The product is very flexible and does what we need it to do, but the support team is great. They're very responsive and willing to lend their expertise to solve our business needs. Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

The organization of some of the features isn't what I expect so it sometimes takes reading the documentation to understand where to find things abd what features are called. Review collected by and hosted on G2.com.

"Developer Friendly Auth"
What do you like best about FusionAuth?

There are a lot of upsides to FusionAuth. The flexibility of the configuration, the ability to host inhouse which increases control,the phenomenal support, very detailed APIs with excellent documentation, full MFA built in without having to move to the enterprise version, unlimited tokens so you don't have to build in a token saving and reuse mechanism. Also, when setup correctly (lol), it works. I'm never left feeling I had to compromise or create some strange hack to get it to work. Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

The only downside, and for us this was actually a bonus, is it took a little longer to get some of the basics going. The quick start guide wasn't as quick as our previous Auth software but with the great support we were able to overcome a couple of issues. We now feel fully in control of the situation and have a deeper understanding of what's goingon. We are excited to dig deeper into the functionality as everything works as you would expect when you do dig deeper. With our previous Auth software we were always wary of digging deeper as it was much harder to get beyond the basics. Review collected by and hosted on G2.com.

"Quality Product, Great Customer Support"
What do you like best about FusionAuth?

FusionAuth took the time to meet with me and my development team to talk through what it was we were looking for. Once it was clear, they presented what options were available and were on hand for follow-up meetings as well. It's not often that a small business like ours gets the kind of personalized treatment that we receive from FusionAuth. When it comes to technical integrations, knowing we can get support when we need it is fantastic. It also doesn't hurt that they were much cheaper than our previous solution and offered straightforward pricing. Review collected by and hosted on G2.com.

What do you dislike about FusionAuth?

There was definitely a learning curve to get started. It took a real deep dive by my lead developer before we felt like we were able to make progress. That said, given the product, I imagine this is true for any such service. Review collected by and hosted on G2.com.
