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.

Our users and administrators have both given positive feedback with using Duo. I would recommend to organizations looking to have reliable and secure logins.

Pros

Multifactor authentication has been effective at making users have to sign in securely to our networks. Duo admin console is easy for our techs to learn and user setup takes a few minutes to complete. The device and user management for sign-ins allows us to manage the authentication more effectively.

Cons

We have experienced the admin console inaccessible at times when there have been updates or outages. The timer for accepting pushes doesn't always sync up correctly.

Alternatives Considered

Microsoft Authenticator

Reasons for Switching to Duo Security

We chose Duo Security over Microsoft authenticator because it was prices better and had better results when testing authentication apps.

Beware! Customer service has been non-existent following Cisco acquisition

Reviewed on 10/03/2020

Pros

We have used Duo for many years. It was easy to implement and has always worked well.

Cons

Last year we negotiated bulk pricing and paid in advance for a 14-month term. Later we discovered that they had never provisioned our licenses and were still billing our credit card. Now, four months later, after numerous phone calls and more than a dozen emails, they have still not provisioned the licenses we paid for. They have acknowledged that this is their mistake and they need to fix it, but they seem incapable of doing so.

I get the sense that their organization is completely dysfunctional following the Cisco acquisition. Given that they cannot solve the challenge of "how does a customer purchase your software?", I am worried what might happen if you came to them with anything more difficult.

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.

We use Duo to provide better security to our end users and to comply with regulatory requirements. The solution is inexpensive, easy to use and integrate with the existing applications.

Pros

Duo is a cheap, flexible solution that allows a company to easily implement MFA on corporate applications.Pros: - Out of the box integrations with applications such as Office365, Salesforce, Microsoft ADFS, etc.- Adding users is easy, with several enrollment methods (automatic, email based, sms based, etc.)- Using the application is easy, it is just a matter of accepting a push, or entering a numeric code.

Cons

So far I haven't had any issues with the solution. It was implemented for Office365 and ADFS in less than an hour.

Overall Duo has helped us improving device security and we were able to integrate with our Palo Alto Firewall devices and had pretty smooth experience.

Pros

This worked pretty smoothly, when logging in the security devices such as firewalls, with duo we made sure no unauthorized users is logging into the devices with Multi Factor Authentication mechanism. With duo we simply were able to compliance with Zero Trust Model, no unauthorized users can make the changes on the system.

Cons

They can work on their mobile application and make sure to improve the user experience, I feel bit delay while receiving the authentication request. Also on mobile app they can make it like only one finger touch is enough to authenticate the user. So less clicks can make the experience way better.

Duo Security is great at multi-factor authentication

Reviewed on 31/08/2022

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

Never had any problems with Duo. I broke my phone once and couldn't authenticate myself to get into any important accounts since it was all tied to my phone only. Duo allowed me to get into my accounts that day fairly easily by giving me temporary backup codes until my phone was fixed.

Pros

Duo is simple to use, user friendly, and does all that is needed for authentication. I work with multiple large organizations that have chosen to use it for their employees. It is easy to pair duo with new organizations as well.

Cons

So many authentication apps exist, that it is hard to distinguish between them. Duo works great, but so does basically every other authentication method in the app store.

Pros

It makes log in authentication very simple. 1 click and I'm in.

Cons

I do not get alerts from Duo when I need to authenticate. I imagine I just have that option turned off and need to look into the settings, however.

Duo Security was the second-in-line when it came to authentication and data security for protecting my device's applications but really fell short when it came to the execution of its actual functionality when the time came. So, within the time period of installing and using the software, I soon uninstalled it in search of another software to satisfy my needs with less complications.

Pros

Duo Security's simplistic design format makes any user, including myself, notice any and every possible feature available and if unsure, can contact their support team who replies in a very short span of time.

Cons

There were times in the past where I would use Duo Security as a two-factor authentication system to login my Instagram account. However, on those times the code that would refresh every 30 seconds was always deemed incorrect. And so I would have to disable the software's functionality and risk my account security to simply login to Instagram.

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

Very easy to use and integrate into daily life. Makes me have peace of mind that no one can hack into any of my accounts. Even if they try to login, I can simply deny their login request. I have been using this for almost two years now, never encountered a problem.

Pros

The ease of use is the best feature. It is simple to operate and makes logins more secure. You can easily link your google account or your bank account from the link option available. To login you can choose to receive a call, or a push notification (phone internet connectivity required) or enter a passcode (provided by the duo app). You also have the option to remember your device for a maximum of 60 days. You can still login if you don't have internet connectivity on you phone by using the "enter passcode option" or simply receiving a conformation call to you phone. And that is pretty much all you need!

Cons

There is nothing to dislike about this software. Although, I would like to point out that you have to be careful of not giving your phone to anyone. Just don't lose your phone.

Really, my experience is very positive. When I am disappointed, it is usually because it work well All The Time so I expect to be perfect, but perfect it a high bar to set for anything. I use three different Dual Auth apps and three physical tokens for different applications and Duo it in the top two in terms for favorite in ease to use.

Pros

The PUSH to mobile functionality is just about as easy to use as you can get. Also, I can use the same app for different authentication of different unrelated systems.

Cons

The Duo PUSH does not ALWAYS work 100% of the time, but does work 90%. Usually when inside or around electronics, but that is to be expected like with text messages or regular phone calls.

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.

Cons

Secure but Time-Sensitive

Reviewed on 4/05/2021

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.

Overall Dou mobile does a great job at storing access codes and having easy access to them.

Pros

The product is very simple and easy to use. After the one-time setup to any 2fa-enabled website or application, you only copy the access code and you're in. The implementation with Canvas, which Oregon State University requires, is seamless. After inserting the university's login information, a notification is sent to the device of preference. You only have to click a button and you're in. This one-click access is dependent to applications that support it, otherwise a copied code is required.

Cons

For mobile application: The only concern is the application doe not have the ability to enable lock, such as FaceID or fingerprint. Therefore, other individuals could access those codes if the phone is unlocked.

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.

1-click for Two-Factor Authentification

Reviewed on 15/01/2019

Pros

I have been an end user of Duo Security for the last 2 years, and I think that this is the best software for 2-factor authentification. The Duo App has a simply designed platform. When we sign into the website that requires authentification, we can just type a passcode provided by Duo App on the website or click an authentification request given by Duo App. Yes, it is that easy with Duo.

Cons

Setting up the Duo from the scratch can be challenging to some people who are not familiar with two-factor authentification. It is important for organizations or companies to provide a step-by-step installation procedure to users before they start using Duo as their sole authentification method.

Pros

I use Duo Security as a part of dual verification sign-in process for university. The phone app was initially difficult to set up and I actually gave up at one point, but once it was on my phone it has been no issues. (I've actually installed and verified a few phones and it always a hassle..) The three options for verifying identify is convenient - call, message, or notification. I generally use notification, but have used call when I had poor cell service. The notification is handy because I do not have to unlock my phone and the notification disappears after you approve the log-in. The time out feature is meant to keep your account secure but can be an issue if you don't have your phone close by/ don't approve in time.

Cons

Selecting "Stay logged in for 7 days" only works sometimes for some reason.

Security at your fingertips... Literally!

Duo has helped me meet my university single sign on security requirement for access to my account. I especially appreciate that I can use Duo with multiple accounts at once. That feature has been the best because I didn't actually have to set up anything new.

Pros

This product keeps your accounts safe and secure. With increasing use of single sign on for workplace accounts, Duo has been useful in providing the multifactor authentication my university requires in order to access my account. One benefit has been the ability to use Duo for security authentication with two additional accounts. Having one program to help manage access has been critical. It's easy to use, once you have made the initial installation, and provides secure authentication with the simple selection of "approve" or "deny" from the notification message itself.

Cons

The initial integration was a bit counterintuitive. Maybe it was that I was new, but once I got over that initial hurdle, it was great.
