We use Fingerprint to catch multi-accounting and linked accounts on our platform, which is a constant issue in online gaming/crypto environments where users try to create duplicate accounts to abuse bonuses or get around bans. It’s been solid for a few months now. The visitor IDs have been stable enough that we can reliably tie new signups back to previously flagged devices, even when someone changes IPs or clears cookies. Integration was straightforward, and it’s made our fraud review process much less manual since we’re no longer relying purely on IP or email matching. Review collected by and hosted on G2.com.

Fingerprint tells us when someone is using a VPN, browsing in incognito mode, or when their browser has been tampered with. Those are signals we never would have been able to catch on our own, so we rely on the flags and act on them. The visitor ID stays consistent even when a candidate switches browsers, clears cookies, or signs up with a new email.

The best part is that we don’t have to configure anything. There are no rules to write, no lists to maintain, and no training required. We simply review what it reports about a candidate and take action, and it has been right almost every time.

Their web app is also straightforward to use. When I need to look up a single event, I paste the event ID into the dashboard and everything related to it like signals, device, browser, IP, and location appears together on one page. Review collected by and hosted on G2.com.

Honestly, nothing specific comes to mind. We’ve been using it for a while now, and it’s just quietly done its job. It hasn’t crashed, it hasn’t unexpectedly changed its behavior on us, and on the few occasions we’ve had a question, the documentation was clear enough that we never needed to open a support ticket.

What I like most about Fingerprint is how accurately it identifies returning users and devices, even when cookies are cleared or users switch browsers. The implementation was straightforward thanks to the well-documented SDKs and APIs, and the response times have been consistently fast. It has significantly reduced duplicate accounts, fraud attempts, and manual verification work. The dashboard is easy to navigate, and the detailed device intelligence helps us make better risk decisions without impacting the user experience. Review collected by and hosted on G2.com.

Overall, the product works very well, but the pricing can become expensive as usage scales. It would also be helpful to have more built-in analytics, reporting options, and customizable dashboards. Some advanced features have a learning curve for new users, although the documentation is comprehensive. Review collected by and hosted on G2.com.

I use Fingerprint to detect high risk and bot suspicious users. It makes it really simple to get all the data I need related to a user and their profile and device. It simplifies the integration complexity and adds a ton of value with its unique fingerprint feature for detecting high risk activities. The SDK was really easy to integrate into React Native and works great for iOS and Android. It provides a significant amount of rich data about the user and their device, and I'm able to use the data and signals it generates to integrate into workflows to detect high risk activity and mitigate risk. I continue to use Fingerprint because it offers rich high signal data when I need it. The initial setup was really easy, and I was able to integrate it within two days.

I really liked how the integration with Fingerprint was extremely smooth. Working with their technical integration specialists and the customer sales representative throughout the process was very enjoyable. I appreciated their transparency around pricing both on their site and in the calls. During a thirty-day pilot, we did a fairly in-depth audit and found the quality of Fingerprint's device fingerprinting to be extremely good, especially when compared to some competitors. The initial setup was extremely easy, with clean and clear documentation and portal. Any problems we encountered were swiftly handled by their very responsive integration specialist who was accessible via Slack. Review collected by and hosted on G2.com.

This is not a dislike, moreso, that Fingerprint is not a full-feature fraud provider, and does not bill itself as one. Building a model ourselves using internal data combined with their device ID to create a composite score for our specific sector is what we ultimately had to do to use this effectively. A lot of the smart signals that Fingerprint collects and exposes are not necessarily 100% correlated with fraud, which mean that the suspect score is helpful, but not the whole picture.

I like that Fingerprint.com is highly accurate and reliable for identifying visitors, even when they use VPNs, incognito mode, or clear cookies. The integration is straightforward, the API is easy to work with, and the documentation makes setup smooth. It also provides very detailed device intelligence, which helps a lot with fraud prevention, bot detection, and understanding user behavior. Overall, it’s a powerful tool that gives us consistent signals we can trust. Review collected by and hosted on G2.com.

It’s not really a downside, but Fingerprint collects a lot of data that can be hard to understand at first glance. It might be helpful to offer more targeted graphs and internal fraud scores that can be tailored to customer preferences, so the information is easier to interpret.

It was user-friendly as it was simple and quick to set up the environment process, and the dashboard navigation is easy. SDK integration is developer-friendly, and it also supports multiple technologies like JavaScript, React, and more. It gives very fast API response with low latency, It performs nicely and is stable even on high traffic applications. The free plan is helpful for testing and exploring the platform. Documentation is clear and easy to follow. It also detects suspicious activities and abnormal patterns in real time. Review collected by and hosted on G2.com.

Scaling costs can be challenging for growing appliaction, High volumne API users should get some better pricing options or discounts, pricing becomes expensive when API usage increases. Review collected by and hosted on G2.com.

We are using Fingerprint to locate users with duplicate accounts, and it provides us with easy identification of these accounts, allowing for more agility in bans and in keeping bans active on the platform. The ease of information persistence is a great benefit, because even if a banned user creates another account using a VPN, thanks to Fingerprint, we can identify and punish these offenders. I love the generous limits for Android on the free plan, as they offer a limit of 500,000 and we barely use 5,000 monthly. The ease of implementation is excellent; it's basically plug and play, everything is very well explained and easy to understand. Our development team didn't have the resources to pay for all the necessary tools, and the initial free plan from Fingerprint was essential, as we like companies that offer initial free services, even if limited. The initial setup was incredibly simple, it didn't even take 24 hours for everything to be up and running. Review collected by and hosted on G2.com.

I believe that the limits for iOS and Web should not be shared. From my point of view, it would be better to have a specific limit for iOS and another for Web. Review collected by and hosted on G2.com.

Fingerprint Pro gives us reliable device identification with minimal engineering overhead. We verify requestIds on the backend, which makes anti-abuse logic much safer than trusting client data alone. Custom subdomain proxying was a big win — better match rates and fewer blocked requests. Setup was fast, and the service has been stable in production. Review collected by and hosted on G2.com.

Pricing can feel steep for early-stage products, and identification isn’t 100% reliable in every environment — adblockers, network issues, or SDK timeouts sometimes mean you need fallback logic instead of blocking users Review collected by and hosted on G2.com.

We started using Fingerprint to stop people from creating multiple accounts just to use our free trial again. It was easy to set up and started working right away. It detects VPNs, proxies and other suspicious signups, which has really helped us reduce fake accounts. We also like that it runs in the background without any extra work from our team.

We haven't had any major issues so far. It would be nice if there were a few more reports in the dashboard to make it easier to understand the data. Review collected by and hosted on G2.com.
