Pros: I have used Duo for Two Factor Identification Security at two different employers so far in my career. It is such an easy to use, efficient and effective application. It eliminates the need to keep track of external network keys, passwords, and other redundant programs. I feel safe and secure with Duo Two Factor Identification because it requires both my phone and fingerprint in order to gain access to protected software.

Cons: Earlier this year I had to replace my iPhone and after I restored my new device from backup my Duo Two Vactor Identification was no longer linked. To my surprise, It took several hours to restore and reset my security settings at work the next morning. Although the Duo reset was quite inconvenient for me that day, restoring software is both an infrequent and uncommon occurrence for me.

Pros: Duo has made it easy for our company to use 2FA across several of our services. It's easy to implement and easy to manage. Duo integrates easily with 3rd party applications and services. Users can use multiple ways to authenticate to Duo.

Cons: Push notifications to Cellphones can be spotty if a user has poor cell reception. Not necessarily a failure on Duo's part but it should be considered if you are going to use the App Push for authentication.

Overall: We wanted a 2FA solution for our VPN and password management solutions. Duo integrates with both. We also needed a 2FA solution that can be used by a wide variety of users. We have many remote users so being able to authenticate via app, text, or phone call makes it easy for all of our users to gain access in a way that is secure and available to them.

Pros: Security Features, Ease of Use, Apps

Cons: Their website is not easy to use because there are so many features available, which might be overwhelming to someone not familiar with it

Overall: Ever since I've started using DuoSecurity to access my website admin interface, I haven't had any breaches in security and I feel safer knowing that hackers can't access my website easily.

I've been using DuoSecurity for several years now and offer it as part of my Security Packages when I launch a client's website, because it's a quick setup and for ease of mind.

I use an app on my iPhone that sends me a notification when I go to log in to my site, allowing me to "Approve" or "Disapprove" access to the site's admin interface easily. I also use it to access other accounts online that allow for a Code to be entered, giving me that piece of mind that my personal information is secure.

Highly recommended!

Recommendations to other buyers: None.

Pros: Unlike other 2-step authentication services that require you to punch in a short, "random" code in order to access your account, Duo Security makes securing an account simpler. Got a smartphone? Download the Duo Security app, link it to an account (typically an email account, though Duo can work with other services as well,) and decide how you want to be alerted about log-ins. The next time you try to log in, Duo will contact your phone, and you'll be able to authenticate your log-in with a simple button-press. That's it.

There are other options as well. If you don't want to use the smart phone, Duo will call a landline and ask if you're the appropriate user for the account. You can also save multiple methods to the same account.

Cons: Linking Duo to my email account took some doing. By and large, it was a simple, step-by-step process. However, I could imagine easily fouling up one of those steps and getting lost and frustrated. There's no problem with the service itself, it's just getting started with it requires a little time and focus. Once it's set up, however, using Duo is completely painless, and its recovery features are simple (in the event you get a new phone, computer, etc.)

Pros: I think it keeps accounts really secure because you can set up the account to be able to send push requests to a finite amount of devices. It's also pretty easy to use because you just press one button and it works very quickly to grant/deny access.

Cons: The 6-digit passcodes that are there that you can regenerate whenever you want are a bit confusing and it's hard to know what those entail. This could be a problem with the school system but it would be helpful if Duo gave some sort of instructions when downloading the app.

Pros: Duo Security makes 2-step authentification simple. After an initial registration of the website that requires 2-step authentification on the Duo app, all I have to do to grant access to the website is clicking approve button on the app on my phone or entering passcode on the website. This software makes 2-step authentification take only 5 seconds.

Cons: I cannot think of any negative aspects of this software. This software is so simple and doesn't have any unnecessary features. There are no parts to be improved.

Pros: I use this as an inbound sales marketer for Carnival Cruise Lines and thoroughly loved it I had no issues with my computer whether I was working or not it did not allow any viruses to get through and no breach of security

Cons: That I had to help make sure my cell phone was right there to confirm my signing in

Overall: I had no issues with Duo security the company I was with I was taking credit cards and personal information and I had no breach of any sort no one getting in and no information getting out so overall it was an awesome experience and if we get back to doing that on our construction side that is definitely a program I would use again and definitely refer others to

Pros: Duo integrates out of the box with a lot of SaaS systems, and it is easy to set up for users. For unsupported SaaS, or in house apps, it possible to set up a lightweight agent running locally on your network that will extend 2fa functionality to unsupported systems. This agent is easy to set up.

Cons: Onboarding users onto the platform in bulk is a bit of a challenge. I wish there was more instructional resources for introducing the product to the company. Sometimes the app freezes when the user is expecting a push, and therefore they are unable to complete the 2fa process.

Pros: We go to Duo after Clef closed shop - Clef was ridiculously easy to use. After trying three other options (dismal failures) we hit on Duo and it has been perfect since. It works fast every time and has good supporting documentation available online. Authentication options are all good and they are all fast, pretty much instantaneous. Duo is well worth it for the peace of mind knowing the website has this layer of security in place.

Cons: Some difficulty getting re-set when I upgraded my phone; followed the simple instructions and had to do it all over a couple of times before it finally "took". Could have just been me, I wouldn't consider this as a real con, more likely user error.

Pros: Duo Security for the most part just works. I very rarely have connectivity issues, I've never had token mismatches or problems of that nature. It does the job it's supposed to do, and does it very well.

Cons: Really my only complaint is that sometimes the push notification doesn't work properly, in a variety of different network settings. But it's infrequent, and I've yet to have a case where I've missed it (because if I'm trying to log in to something, I know I'm doing so and can pop open the app if need be).

Pros: It is very good that it is compatible with Apple Watchcon. The design is very intuitive and has an excellent Interfax, you do not need training to use it. In addition, the documentation they provide is well written. Support is quick answer any question. The end-user experience is very simple and easy. The product works and they have given us great support by bringing systems online. DOU is the best product I found in the market.

Cons: I'm just saying it's expensive. It is the only bad thing that this product has. I think we are getting all the quality we want ... DOU is necessary for the company and I do not regret using it.

Overall: DOU was a great choice in everything. Compared to some of the other multi-factor platforms, this is by far the easiest to manage and configure. This product gave the company a clear and clear documentation, which reflected its platform as one of the best. It is the best choice.

Cons: I wish I could include other websites/softwares to my duo token but it doesn't seem to work just yet with my other accounts. I'd love to eventually be able to keep all of my accounts secure through a quick easy app and I think with a little time Duo could be that app

Overall: So far it has been a breeze. I have yet to encounter any bugs, and it is pretty straightforward once you link your account to it.

Cons: It's a bit difficult to set up and get going. Adding users can be complicated depending on how the individual accounts are configured.
