A solid identity platform that just works for our apps
Reviewed on Feb 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
Reviewed on Feb 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
Reviewed on Feb 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
Reviewed on Feb 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
Reviewed on Jan 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.
