Unmatched Ease and Flexibility for Identity Management

  • March 20, 2026
  • Review provided by G2

What do you like best about the product?
We use FusionAuth as our primary identity system for user authentication and facilitating SSO with larger clients. I love its full-featured identity management with added security, like MFA. It's very easy to implement, offering almost unlimited flexibility for any desired solution. The onboard and pilot team is fantastic, providing invaluable insights on advanced features as we grow. There's no easier identity solution to set up and deploy, and I wouldn't change a thing as we've had zero issues.
What do you dislike about the product?
Nothing. I would not change a thing.
What problems is the product solving and how is that benefiting you?
We use FusionAuth for identity management and SSO, benefiting from its full-featured security and MFA capabilities.

Affordable, API-Driven, and Stellar Support

  • March 18, 2026
  • Review provided by G2

What do you like best about the product?
I use FusionAuth to handle customer identity management across our product suite, and it has been valuable due to its affordability at our scale compared to Auth0 or Okta. I really appreciate that the platform is fully API-driven, which allows us to automate client and user onboarding, saving us time. The direct communication with FusionAuth solution architects via a private Slack channel was crucial in meeting tight implementation deadlines. With FusionAuth, we can get faster results by going directly to the source, unlike Okta and Entra where we relied on the general developer community. Moreover, the initial setup was relatively straightforward, and we were able to purchase FusionAuth for less money while obtaining more functionality than we had with our Okta subscription.
What do you dislike about the product?
We ran into some challenges with mixing single tenant applications and multi-tenant applications but we were able to work around it.
What problems is the product solving and how is that benefiting you?
FusionAuth offloads the risk of managing sensitive credentials, is more affordable than alternatives like Okta, and its API-driven nature allows us to automate onboarding. Direct access to solutions architects accelerates problem-solving.

Flexible, Developer-Friendly Authentication with Easy Integration

  • March 18, 2026
  • Review provided by G2

What do you like best about the product?
What I like most about FusionAuth is its flexibility and ease of integration. It provides strong authentication features while still being developer-friendly and customizable to different use cases.
What do you dislike about the product?
At times, the configuration and setup for more advanced, out of the box scenarios can be a bit involved, but overall it’s manageable once you’re familiar with the platform.
Also reporting could be more dynamic
What problems is the product solving and how is that benefiting you?
It takes away the complexity of building and maintaining authentication from scratch. With features like social login and user management handled in one place, it saves time for the team and makes the experience smoother for users.

Flexible Self-Hosted Solution with Great Documentation and Support at an affordable price

  • March 15, 2026
  • Review provided by G2

What do you like best about the product?
Supports self-hosting. The documentation is solid for setup and for automating workflows using APIs. Support has been responsive in my experience. It also covers multiple scenarios without compromises, including multi-tenancy, user and group management, federation, and M2M tokens. Finally, the pricing model is clear and attractive.
What do you dislike about the product?
There’s a lack of a built-in tenant discovery flow on the login screen.
What problems is the product solving and how is that benefiting you?
We were looking for a solution to manage authentication for our SaaS application, where multiple tenants can either manage “local” users and groups or import their own users through SSO. Our application manages thousands of devices per tenant (while each tenant only has hundreds of users), so we need far more M2M tokens than user tokens, which FusionAuth handles at no additional cost. On top of that, the ability to self-host significantly reduces the compliance requirements we have to meet with our customers.

A solid identity platform that just works for our apps

  • February 26, 2026
  • Review provided by G2

What do you like best about the product?
I like how easy it was to get FusionAuth up and running and having a full login and user management system in place. The documentation was clear and helpful and I could plug it into our web app with little fuss. The dashboard is simple and gives me quick access to users roles and settings without having to dive into the database manually. I also appreciate the support for multiple authentication methods so our users can sign in in ways that fit them.
What do you dislike about the product?
The theme customization felt limited and took extra time to bend it to look like our brand. Some of the more advanced workflows were not intuitive and I had to piece them together by trial and error.
What problems is the product solving and how is that benefiting you?
FusionAuth took the pain out of building our own user identity system. Before we were juggling custom code for login sign up password resets and session handling. Now all of that is handled properly and securely which has freed our team to work on our core product. We were also able to add two factor authentication quickly which gave our customers more confidence in our security.

The Good News About Password Sharing - FusionAuth

  • February 25, 2026
  • Review provided by G2

What do you like best about the product?
The most valuable part of the software is the shared folders themselves (that was the real game changer) - You provide the Servicedesk Team with what they need to know, the Systems Team gets all that AND more, and NO ONE is putting their login credentials into Slack or trying to keep a Google Sheet that has three people with EDIT ACCESS as a way to avoid password sharing. Credentials remain encrypted and no one will ever have to look at your password unless you want to show them.
What do you dislike about the product?
Autofill shows up in almost EVERY INPUT FIELD on EVERY PAGE, regardless of whether it is a password field or not. And there is NO WAY to quickly disable Autofill for a particular site without going through the Settings options. That becomes old FAST. Switching from a Personal Account to a Business Account is CLUMSY - I am unable to View both Accounts at the same time, I just bounce back and forth, which BREAKS Autofill HALF THE TIME. Petty One: Save Prompt comes up for 2-3 pages AFTER you have already DISMISSED it ONCE, one reminder is ENOUGH. Also, no SubFolder Structure, which makes Organizing a LARGE Vault much more annoying than it should be.
What problems is the product solving and how is that benefiting you?
Prior to this, our passwords were being stored in SPREADSHEETS on SHARED DRIVES OR SENT THROUGH EMAIL/CHAT, which is a terrible situation waiting to happen. FusionAuth stores all of our passwords in an Encrypted Place WITH ACTUAL ACCESS CONTROLS, so each user can ONLY see what they are allowed to, New Hires receive Access to what they need on DAY ONE, and when someone Leaves, YOU KNOW EXACTLY WHAT THEY WERE ALLOWED TO ACCESS. It also eliminates the use of duplicate passwords, since the Generator does all the heavy lifting. THAT IS IT. THAT IS THE ENTIRE VALUE OF THIS PRODUCT, and it DELIVERS.

Flexible and Reliable Authentication Solution

  • February 25, 2026
  • Review provided by G2

What do you like best about the product?
I like FusionAuth because it is flexible and developer-friendly, allowing full control over authentication and user data. It saves me time, makes integration smooth, and lets me customize authentication the way my application needs without fighting the system. It's also reliable and handles login, registration, and roles seamlessly. Plus, the initial setup was relatively straightforward with clear documentation.
What do you dislike about the product?
Some parts of the documentation and advanced configuration can feel overwhelming at first, and simplifying the onboarding experience would make it even better
What problems is the product solving and how is that benefiting you?
FusionAuth handles login, registration, password resets, roles, and API security, freeing me from building authentication from scratch and letting me focus on product features.

FusionAuth manages passwords securely with ease

  • February 11, 2026
  • Review provided by G2

What do you like best about the product?
Honestly I think the biggest benefit is that I don’t have to remember a million different passwords anymore and since we use it for work and it handles everything from generates strong passwords whenever I want one and stores them automatically and populates passwords when I log in somewhere. The password sharing feature has been especially convenient because our whole team needs to get into some accounts and before we would just send them over slack which likely isn’t ideal.
What do you dislike about the product?
They had me make a master password which made sense but then they wanted me to make another password as well? And I wasn’t entirely sure if these two passwords were supposed to be the same or if they should be different as the wording of that section wasn’t very clear. And sometimes it even comes up randomly on forms fields that don’t require it, and I have to navigate past it to complete things normally.
What problems is the product solving and how is that benefiting you?
We are a small team and everyone had kept their passwords in notebooks or reused the same ones all over the place which obviously was not secure. FusionAuth solved that problem for us by providing an easy-to-use solution for our entire team to safely share login credentials without sending them via chat or email.

FusionAuth: Essential for Security Research with Easy Setup

  • January 16, 2026
  • Review provided by G2

What do you like best about the product?
I like that FusionAuth helped me in getting some details about my past accounts, like where the account was created and by which server and browser. It gives me partial access to important information, which is crucial for my research on vulnerability and identity theft. Also, the initial setup of FusionAuth was quite easy.
What do you dislike about the product?
I don't like how FusionAuth is available for everyone, which means while I'm using it for my research, others can use it against me to get my information reversed or changed. It would be better if there was a way to enhance privacy, like adding face or retina authentication so that no one can misuse it.
What problems is the product solving and how is that benefiting you?
FusionAuth helps me research data lost due to security vulnerabilities, providing partial information about account creation details like server and browser used.
