A safe, easy-to-use platform for authentication made our SaaS projects much simpler.

What do you like best about the product?
I love how FusionAuth is so developer-centric and flexible. It took me just days to integrate it into our SaaS platform, rather than the weeks of authentication setup we used to go through. The flexibility related to user authentication flows, specifically multi-tenant login, social login, passkeys, and biometrics, is just outstanding. Universal logins along with two-factor support were quite a professional first-day undertaking in terms of security setups.
What do you dislike about the product?
The major drawback that I have faced has to do with pricing clarity as one scales. For startups or teams who have just started with user authentication, it is not always obvious wherein the long run the cost implications lie. It would be very useful if FusionAuth was clearer on its cost structures at scale.
What problems is the product solving and how is that benefiting you?
We have pretty much brought all our authentication systems for numerous web apps onto one platform through FusionAuth. Creating and keeping up login and confirmation functionalities had been quite tedious and chaotic for our team to do piecemeal. But after implementing FusionAuth, we were able to fastly deploy secure APIs along with MFA and Single Sign-On without reeling under many errors.

FusionAuth Is a Beast Once You Tame It — Secure, Powerful, and Occasionally Infuriating

What do you like best about the product?
What really won me over with FusionAuth is how naturally it fits into our Microsoft-heavy environment. Setting up SSO across Outlook, Teams, and SharePoint felt like flipping one big switch — suddenly, people weren’t forgetting passwords or pinging IT for access issues every other day. Conditional Access is one of those features I didn’t know I needed until I had it; I can allow access based on location or device, which has been huge for our remote team. Also, being able to roll out MFA using the Microsoft Authenticator app made our compliance team very happy without annoying our staff.
What do you dislike about the product?
The initial setup almost broke me. Trying to integrate FusionAuth with our older on-prem Active Directory was like stitching two universes together, and don’t get me started on SAML — it feels half-baked compared to Okta’s clean implementation. Also, some of the policies become a labyrinth over time; one misstep and you’re locked out of your own admin portal wondering what went wrong.
What problems is the product solving and how is that benefiting you?
Before FusionAuth, managing user access felt like whack-a-mole — new hires, password resets, inconsistent MFA rules across tools. Now, I can onboard a new employee in minutes: create the user, drop them into the right group, and they’re good to go with full device-level security via BitLocker and conditional access.

Strong, Scalable MFA with Some Friction: FusionAuth Delivers Where It Counts
Reviewed on Jul 13, 2025
Review provided by G2
What do you like best about the product?
What I appreciate most about FusionAuth is how seamlessly it secures our environment using multi-factor authentication (MFA) without compromising on usability. The FusionAuth Push feature is by far the most convenient — I just tap my phone to approve access, no codes needed. Its integration with Microsoft 365, on-prem Active Directory, Meraki, and even third-party apps like AWS and Falcon Antivirus has made deployment very flexible across our stack. I also really value the Unified Endpoint Visibility dashboard — it gives me a clear view of every device accessing our systems, from corporate laptops to BYODs.
What do you dislike about the product?
FusionAuth’s setup process can be overwhelming, especially when configuring SSO with on-prem systems — the documentation is there, but it demands careful reading. It’s also frustrating that you need internet access for it to work; there's no offline mode fallback. And while the mobile-first experience is great, it becomes a problem if the phone is lost or forgotten — you’re effectively locked out.
What problems is the product solving and how is that benefiting you?
By enforcing MFA and verifying the security posture of each device (OS version, encryption, etc.), it reduces our exposure to phishing, stolen credentials, and insider misuse. FusionAuth has been very helpful in meeting insurance and compliance needs for me as someone who works in a regulated field. Compared to free alternatives like Google Authenticator or Microsoft Authenticator, FusionAuth stands out by offering push notifications, endpoint trust policies, and integration support — features we rely on every day.

FusionAuth: Serious Security with a Surprisingly Smooth User Experience
Reviewed on Jul 07, 2025
Review provided by G2
What do you like best about the product?
What I appreciate most about FusionAuth is how seamlessly it balances strong multi-factor authentication (MFA) with flexible integration into our existing infrastructure. The Duo Push-style interface, where users can just tap a notification instead of putting in codes, makes it more easier for people to use, even teams who aren't very tech-savvy. We’ve even been able to scale usage across over 2,000 endpoints without breaking a sweat.
What do you dislike about the product?
The initial setup, especially configuring SSO with on-prem Active Directory or federated 365 domains, required a lot of careful reading and re-reading of documentation. It’s not something you want to rush, and integration with legacy systems wasn’t as plug-and-play as we’d hoped. Sometimes, the authentication pop-ups don’t appear unless the app is manually opened, which frustrates some of our users.
What problems is the product solving and how is that benefiting you?
FusionAuth has helped us make sure that only authorised people may access critical data in a safe and compliant way. This gives IT admins and end users piece of mind. We operate in a regulated industry, and FusionAuth's flexible MFA methods (push notifications, passcodes, biometrics, etc.) meet those security requirements without adding friction. We considered Microsoft Authenticator and Google Authenticator, but FusionAuth won out due to its granular device tracking and integration-friendly architecture.

Reliable Identity Management for Modern Fintech Needs

Review provided by G2
What do you like best about the product?
FusionAuth has been a bit of a game-changer for us—not in the flashy, overhyped way some tools promise to be, but in a grounded, reliable kind of way. What I’ve come to appreciate is how it quietly takes care of the identity chaos that used to haunt our stack. Setting up OAuth2 and SSO was surprisingly smooth; I had our core app talking to FusionAuth in under ten minutes, which honestly shocked me after wrestling with tools like Keycloak in the past.
What do you dislike about the product?
Multi-tenant setups took some brainpower and trial-and-error, especially since our team doesn’t live and breathe IAM. The reporting side also feels undercooked—it gives you the basics, but if you’re used to slicing and dicing access logs like you can with tools like Okta, you’ll feel a bit boxed in. And while support is helpful, I’ve had moments where I wished for a bit more than just a link to the docs when tackling edge-case scenarios.
What problems is the product solving and how is that benefiting you?
We no longer have five different half-baked login flows duct-taped together, and managing access across environments doesn’t require a prayer and a late night. The fact that we can host it ourselves gives us peace of mind—especially in Fintech, where compliance paranoia is kind of the norm. Compared to Auth0, which got expensive fast, and rolling our own solution (which was a nightmare I’d rather not revisit), FusionAuth hits that sweet spot: flexible enough to grow with us, stable enough to trust, and just opinionated enough to keep us out of trouble.
