It's all about security

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.

J.L. Duo Security Review

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.

Duo Security is a bit of a double-edged sword

Duo Security is necessary and useful when trying to protect your secure access to portals and data online. However, this company hasn't quite worked out the delays and programming bugs that still come with the app.

Pros

Duo Security does resolve many issues with sensitive information and secure access, as the approved user is given sole access by having this app on the user's phone.

Cons

There are numerous delays in alerts and sometimes it appears that programming bugs cause the app to malfunction, even when using the latest version of the app.

Great Security

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.

Duo Security Review

Pros

One thing I really like about Duo Security is that you can secure many things with the app. I mainly use it to log into anything that's school related, but there can another layer of security for other things like social media accounts.

Cons

One thing I don't like about Duo Security is how often it tells me to redo the two factor authentication. I get the importance, but it's so annoying when you're in a rush and you see that you need to log in to the Duo Security app to continue. It's even more frustrating when it refuses to connect at times.

An Extra Layer of Security

Overall, it's been a great experience. We implemented it so that we could have unified MFA over multiple platforms--VMware and M365, for example. It also gives users who don't want to use an app on their phone the option of using a hardware key. Setup and integration isn't too rough and the support is excellent.

Pros

Being able to manage multi-factor authentication from a single point is the biggest benefit to this software. When you have disparate systems, all offering their own implementation of MFA, management becomes an issue. Duo solves that issue.

Cons

The administration interface takes a while to get used to. If you stay away from it for a while (when no one has any issues with it) it takes a bit to re-orient yourself.

Excellent security app for authentiction

This is the best security feature for authentication. It makes sure no one else logins to your account but only you. The main benefit of this software is that our work done till date is secure in our machines.

Pros

The best thing about this software is that we can not login to our work station until and unless we pass through Duo Security. There is a mobile app for this which makes it easy to authenticate. We just need to tap "Approve" on the login request sent to mobile app. there are three types of login. One can choose any type based on our convenience. One can login using passcodes, call on spot or just clicking approval system.

Cons

There was issue when I lost my mobile phone and I wanted to configure duo again to login to my work station. Adding account was so time consuming that I had to wait for the Administrator to add my account again. If administrator is on leave then we have to wait for another complete day to login to work station.

The best tool for MFA

Pros

Duo provides a layer of protection that companies need to keep their employees protected. Strong passwords alone are not enough to keep social engineering attacks and credential harvesting schemes at bay. This is why Duo is the product companies need in order to keep themselves protected.

Cons

Sometimes setup can be laborious. Users may have a difficult time with adoption, especially those who are resistant to change.

Two-factor authentication that just works!

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 Security a MUST have!

The software was literally installed in less than 5 minutes with the help of our IT departments. Multiple questions along with your personal log in allows this to serve as a protection not only for the clients we serve but for me as well should anyone ever attempt to access using my identity.

Pros

This process is ABSOLUTELY a must have in todays cyber world. Using a dual authentication system to access your internet services was easy to set up and even easier to install and use. Any work environment where sensitive or personal data, demographics, or financial information should all be required to provide their employees with this type of DUO security. It is installed easily with the use of your IT department and changes, revisions, updates are also handled by them as well. It truly is a better way to make sure we are doing all we can to keep our internet and services safe.

Cons

Honestly I had no issue with the install or the software.

A simple solution that works

Duo Security performs as it claims and works well. It's simple, and I don't have to think when using it, which is great.

Pros

I like the convenience factor most. Some two-factor authentication solutions take some time (entering a code, etc.), but I love how Duo has an Apple Watch widget that allows me to make a single click to authenticate. I also appreciate the simplicity of the UI. I also like the QR code pairing that some sites have to set up the Duo config. It's quick and easy.

Cons

I have no complaints, so it's difficult to write about what I like least. If I were forced to make a suggestion, it would be to make the mobile app more visually appealing.

Duo Security: Secure yes but keep phone close

Maybe Duo should incorporate other ways to allow access alongside mobile devices. The reason being many a time mobile phones are not connected to the internet or not in the vicinity.

Pros

Our university switched to Duo securities some time back for authentication purposes. Security, of course, increased several folds. Also, Duo allowed multiple login/authentication. The enhanced security becomes very prudent when dealing with sensitive data.

Cons

Be ready to keep your mobile phone close to you when you want to access the accounts that need authentication via duo. My biggest issue is the extreme dependence on mobile phones. If the phone is lost or not in your vicinity, it becomes cumbersome to log in. Also, once you login the software sends a push notification to your mobile. The duration that push notification remains active is significantly less. There have been many instances when a notification was pushed to my mobile device, and my device was not within my reach. By the time I retrieve my device, the push notification expired.

Increase the security of your accounts

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.

Pros

Easy to use. Allows smooth and detailed authentication of unknown users which protect the company from cyber frauds. Very secured tool by cisco and widely deployed in many organisations. Their application on mobile is also smooth and great. It protects user's data in the safest way

Cons

Third party integrations with tools and software in which we want to add MFA or authentication can be hard sometimes due to compatibility issues with this tool. Secondly, there are lots of tools in market which provide similar features and IT security protection in cheaper prices.

Duo Review

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.

Duo Security will make your account secure

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.

1-click for Two-Factor Authentification

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.

Good

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.

Super easy to use mobile 2-factor authentication software

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.

Great for keeping you secure

My institution uses it to keep our information secure and it does a great job of keeping it secure.

Pros

Duo is used by my institution to keep our information safe. We use the DUO factor login and it is easy to set up and to use. You download an app on your phone and it will call/text/ or send a push notification when you login to your website. It works seamlessly and never seems to have a problem.

Cons

It can be a bit of a pain when you leave your phone in your office or somewhere else and then go to login to a company site that needs the authentication with DUO. You can't login with out your phone and it can end up being a hassle. But, it does keep your information secure.
