### "It's needed, and it gets the job done"

September 21, 2023

4.0

It's been fantastic when it works, which is 99% of the time, but man, that 1% is not super fun, but all programs have problems, I'd say this is most likely still one of the best choices.

Pros

What I most like about duo security (considering it's application that basically has one purpose with a few different avenues of getting there) is the simplicity. It also is a bit more modern feeling than your email and text authenticators, which is nice. I'd say that this program, if you're looking into authenticating software's, is most likely one of the best choices, next to microsoft's.

Cons

I've randomly (very rarely) had my duo logins just removed from the app, and it is a HASSLE to get everything back ESPECIALLY if you are incorporating this into a business. You're basically having to prove duo screwed up to try to get your authenticating account back onto the program, without having it on the program, it's not super fun, but at least it doesn't happen very often, other than that, great program.

### "Super easy to use mobile 2-factor authentication software"

June 29, 2022

5.0

I have been using it for over 2 years and have never had an issue. It is very easy to use.

Pros

The way it connects to Cisco AnyConnect VPN so that I can safely connect to my work's network. I don't have to worry that someone will get into their network via my account because Duo is tied to my cell phone. It's very easy to use, you just open the app, click the show button on the 6 digit code, and punch that into AnyConnect when you try to connect. They also have an apple watch app so that you can receive the notifications on your watch to log in.

Cons

No qualms. It does what it's supposed to and does it in the most lightweight and streamlined way possible.

June 30, 2022

5.0

I feel more secure in knowing my personal and work information are safe by using Duo Security.

Pros

I use Duo Security for multifactor aunthentication to log in to my work and univerity email accounts. It is very easy to use through my phone application or sometimes I also request for a phone call to verify my identity.

Cons

It is a bit of a hassle to reinstall the app and get it to work when you change phones.

### "A great option for Multifactor Protection"

December 27, 2023

5.0

Pros

Duo Security was fairly easy to setup and our end users took to it well. There are a lot of customizable settings to protect our district data in the best way.

Cons

I have not run into any issues with Duo Security as a end user or an administrative user.

### "Simplified Security"

April 26, 2022

5.0

I enjoy the endpoint security perspective of the application coupled with the simplistic user interface - this is very good for non-tech users working remotely.

Pros

I like that Duo let's you know what might compromise your experience on a platform. It tells you to upgrade your android/iOS handset and gives a severity level. This is great from an endpoint security perspective.

Cons

At times - the app takes a little time to prompt the user that an attempt is being made. This may be a function of slow infrastructure, but it is hard to assess.

### "Best For MFA"

August 17, 2023

5.0

Duo was an easy transition into the MFA world for external access to our internal systems.

Pros

It can integrate seamlessly with all platforms and apps of our organization. Easy to install, use, track, and recover from lost or damaged phones. It has push notifications and also alternate access via text or call.

Cons

Sometimes it takes a couple of times to sign in to a network.Sometimes due to poor data access on the end user part, a push notification doesn't come up although data is available, Which leads to a timeout. A little bit difficult in the initial configuration.

### "Versatile and Secure"

July 15, 2021

5.0

I feel much more secure with many of my accounts. It provides as overall sense of ease and security.

Pros

Duo security has an easy to use app that can serve as a two-factor identification hub for many types of accounts. I find it especially useful for protecting email and bank accounts. The push notifications are convenient for managing login in attempts and ensuring accounts are not compromised.

Cons

Sometimes the notifications are not immediate, and the login in attempt can time out. The software doesn't function well if network connection is poor.

### "Best Two Factor Identification App"

November 27, 2018

5.0

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.

### "Duo Security is great at multi-factor authentication"

August 31, 2022

5.0

Pros

I liked that it connected to my phone and it was easy to get the passwords and respond to the notification to sign in. I liked that my organization valued my security and was investing in products to keep me and my data safe

Cons

It took some time to adjust to this software but that was because it was the first multi-factor authentication that I used. Now that it has been a few years, I am fully on board and don't find it inconvenient anymore

### "Two-factor authentication that just works!"

September 30, 2019

5.0

Our organization has been using Duo Security two-factor authentication for years. The entire solution is incredibly reliable. The mobile app works great and is very easy to use. End-users can quickly and easily enroll their own devices via a self-service portal. This is very convenient whenever you get a new phone. Approval notifications can also be sent via phone, text or push. Push notifications are also supported on the Apple Watch. Although it's rarely needed, online support documentation is very robust. The best thing about Duo Security is...it just works, every time.

Pros

\- User-friendly self-service portal for new device enrollment and management - New account setup is easily done via scanning a QR code - Multiple options for approval codes or notifications including phone, text or push (includes Apple Watch) - Push notifications can be approved directly from the iOS lock screen - Approval is also compatible with Face ID on iOS devices - One-time bypass codes can be used for lost devices or temporary access - Support for Universal 2nd Factor (U2F) security tokens - Great online support and documentation library - Flexible subscription plans with affordable pricing

Cons

When using an outdated version of the app, iOS push notifications just stop working without any error message or notification

### "Duo is a standard and effective tool for secure access"

April 29, 2021

4.0

Duo security is my main program for two factor authentication, and I will continue to use it for this! I like how simple and easy to use it is, and I am thankful that I can trust this program to help secure my accounts.

Pros

I like how simple and straightforward Duo is as a tool -- when I need to connect to a program requiring two factor authentication, I can simply attempt the login and Duo prompts me via my phone, which I can then authorize. I like how simple and straightforward this tool is, and I am grateful that it helps me secure access to my private accounts.

Cons

What I like least about Duo is how limited the features are of this tool. Sometimes I need to connect to an account using Duo but don't have internet on my phone, and I wish Duo provided alternatives for authentication via computer or phone, but this program lacks these features.

### "Robust and easy to use"

January 13, 2023

5.0

Protecting network security is essential for higher ed, and tricky (many users, many types of devices, etc.); this product has stayed stable and reliable.

Pros

Duo seems to work consistently, can be updated without issues, and automatically transfers when I change mobile devices

Cons

Initial installation took a while, at least on my iPhone

### "Increase the security of your accounts"

April 15, 2020

5.0

I like to app and I recommend it to anyone who wants to increase the security of the accounts.

Pros

It has been three years that I'm using Duo. This is the app that my university has decided to use to increase the security of accounts of faculties and students. I feel secure when I use the app. You can use several options for second authorization. it can send a push message to your mobile, you can enter a passcode, which is great. In addition, it does not take too much time to confirm the authorization.

Cons

I think it is a nice app. But I think if it had some other options to log in, that would be great. I myself prefer receiving a passcode in my email rather than using my cell phone all the time. All in all, I think if they work on the app and improve some sections, it would get better and better.

### "I love the different options provided for authentication "

May 18, 2023

5.0

Pros

I love the different options provided for authentication such as duo push, phone code, and phone call. These options make it more accessible to use the software. In instances where I can't use my phone, I can simply use a code for authentication. I also like that some sites allow me to authenticate just once a week as opposed to every time. Furthermore, I like how it can connect to my other devices. I often use my Apple watch to accept the Duo code and it makes it just much easier to use.

Cons

Sometimes the code doesn't work and I have to write down a bunch of code to find one that works

### "Essential additional layer of network protection "

November 24, 2023

5.0

Pros

Provides an additional layer of security when logging into servers, firewalls, switches etc when offline MFA security or local administrator accounts. If the internet is detected a simple notification to Approve/Disapprove is set out to the mobile app. If the internet is offline you can use rolling codes to still login whilst maintaining essential security.

Cons

The administrative interface can be still confusing when setting up Users and Groups and often links are hidden away in large sections of text. Try setting up RDP and locating the Duo EXE and you'll know what I mean

### "If DUO doesn't work, expect your company to be shut down for an unknown amount of time"

April 4, 2022

1.0

I was solving authentication, I will be investigating switching to another MFA solution as soon as possible.

Pros

Our company switched Managed Service Providers, and we used DUO. When we switched over, DUO authentication stopped working. We had multiple users who DUO simply stopped working for. We and our MSP were unable to contact DUO support after multiple hours. I did get through to a person who put the phone down and appeared to be watching a video on YouTube in the background for about 10 minutes and then hung up on me. This had a serious negative impact on our business and I'm surprised that we were unable to get anyone to assist at all with such a business critical feature.

Cons

That when support is needed you can spend multiple hours on hold without any assistance. When someone does actually pick up the pick up the phone and place it on their desk and do not actually answer the call.

Reason for choosing Cisco Duo

I would not choose DUO over any product

### "Duo Security - Easiest DFA hands down"

December 10, 2019

5.0

We love Duo Security. The implementation on our remote servers and web servers gives us piece of mind knowing that our important infrastructure is secured with DFA/2FA (Dual or two factor authentication). It's very easy to setup DFA on a remote server which is good too.

Pros

I like the integration with mobile and smart watches. I use Duo on a daily basis to login in to servers and online services. What I love the most is that as long as I'm wearing my smart watch I can approve logins directly from it. No passwords, no pins, biometrics needed. The authentication push is instantaneous which keeps the login on the target device/service from timing out.

Cons

What I like least is the quality of the hardware tokens. They don't seem to last very long (less than 1 year) and have to resync'd once or twice annually. For me this is no longer an issue because I authenticate using mobile or smart watch pushes. It would be nice to know that if my watch or phone were to die that the token is always reliable.

### "Secure but Time-Sensitive"

May 4, 2021

4.0

Pros

I use Duo on a daily basis to login to my company's VPN and again for internal company resources. Once it's setup it's pretty easy to use. I appreciate that it syncs with my phone so I can just click a button on my phone to ensure it is me.

Cons

I have to login to Duo twice a day and I usually do it at the same time. If I do them too closely together, one of them will say it timed out and I have to start the process all over. If I close all of my internet windows, I have to re-certify everything again so that can be annoying. Also, I purchased a new cell phone after several months of using Duo. It did not recognize my new phone and kept sending my codes to my old phone. It was a frustrating process to reconfigure everything to log on for work. On top of that, I don't love that I have to use my personal device to log on to my work device. It's another app that takes up space on my personal phone.

### "Nice Little Authenticator App"

May 5, 2022

5.0

Pros

It's quite simple and easy to incorporate into simple software/systems that require multiple user access. Easy to add systems and accounts to its setup and easy to navigate.

Cons

It doesn't allow for automatic pushes to be sent once you are trying to log into a software or system. So you have to click to send the push every time and with the experience of other authenticator apps, you might end up forgetting you have to manually pushing it.

### "It's all about security"

March 3, 2020

5.0

Overall, Duo gives me peace of mind knowing that I am the only one that can access my personal data base from log ins and websites. I like knowing that I can approve or reject any log ins from the commodity of my phone.

Pros

Duo is a great option to keep your personal information secured. I like that it requests security validation before logging into websites, and that you have the option to use the app to sign in to any device with a few taps. It is easy to use once everything has been set up correctly.

Cons

It can be hard to understand at first, and it might seem a little annoying to have to confirm you are the one logging into your websites every time, but it gets easier if you have the app. Another thing Duo could improve on is the fact that it only lets you "remember" one device at a time. Sometimes I need to log in from my work laptop or my personal laptop and it becomes tedious to remember which device I have registered.

### "2FA For the Enterprise"

September 5, 2018

5.0

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

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.

### "Duo Security will make your account secure "

October 29, 2019

5.0

I started using Duo Security since 2017 when I started working as graduate assistant. The app had allowed me to make sure that my account at my job is secure and no one can easily access to my account without an approval on my phone. If you are using this app, you don't have to call or text your number to access to your account. You just press the push button and approve it from your phone and access to your account.

Pros

The app is very functional and easy to use. It makes the users to secure their accounts and make sure that no one can easily login to their account.

Cons

You should make sure that your phone has sufficient battery. If your phone battery dies, you might not be able to access your account on your computer. The slight side effect of using this app is that you just have to have an open phone.

### "Great program for security"

December 8, 2023

5.0

Overall great. Easy to use. Quick verification. Like the test or call option.

Pros

Easy to use. Love the access to this on my phone. Provides great security measures to avoid unauthorized log in.

Cons

Requires multiple log in pushes when changed from different applications within the same program. One verification per program would be nice.
