Pros:

It does a great job of being straightforward and keeping your accounts secure. It provides new codes on a 30-second basis, making it difficult for hackers to do what they do.

Cons:

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.

Cisco Duo is more than 2-factor Authentication

5.0 6 months ago

Pros:

Duo not only provides 2-factor authentication but also provides security posture checking for a dynamic behaviour of an endpoint.

Cons:

Duo is purely cloud-based and does not have an on-premise setup.

Outstanding MFA Security

5.0 last year

Comments: 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.

Duo Security is a bit of a double-edged sword

3.0 last year

Comments: 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.

J.L. Duo Security Review

4.0 2 years ago

Comments: 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.

Doesn't Get Much Simpler...

5.0 3 months ago

Pros:

Duo Security made it quick and easy to sign into the desktop computer and additional computer programs requiring authentication. It only required a fingerprint rather than typing in a number like other authenticators.

Cons:

It would prove tedious if I did not have access to that specific phone for any reason, but that's probably the case with all authentication devices.

Reliable and Fast

5.0 3 months ago

Comments: Very positive, it always functions the way I expect.

Pros:

The mobile app makes MFA less of a pain by speeding up the process by being able to select "approve" rather than receiving SMS codes to tediously type into a website

Cons:

Can't think of any negatives, it functions fast and exactly how I need it to.

Pros:

I liked how easy it was to log in with it, as the notification pops up and works instantly. the app was easy to use once connected

Cons:

setting up a new device was challenging, for example if you did not have your phone with you bypassing the authentication with another device was not easy.

Duo Security is the best for Two Factor Authentication

4.0 last year

Comments: I've had too use it to access my work accounts for many years, I can use my smartphone or my own USB fob which was given to me, so you can see I've been a captive user for a long time.

Pros:

It's the best Two Factor authorization solution. Most convenient as I can use either my smartphone or a USB fob, as the 2nd factor.

Cons:

Just like any two factor solution it takes much more effort than just a single factor login.

Best For MFA

5.0 last year

Comments: 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.

Duo Review

5.0 2 years ago

Comments: 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 2FA Daily Use

Comments: Duo has made it simple to login everyday as 2FA and single sign on

Pros:

You can easily approve your Two Factor Authentication right from the notification or open the app to approve. Can have multiple Duo programs under the same app.

Duo Security for Enterprise Authentication

5.0 2 years ago

Comments: High level of performance solved our remote worker VPN security issue.

Pros:

We use Duo for MFA, Desktop security, VPN security and they all work from an employee's mobile device.

Cons:

Sometimes the connection between the user's mobile device and Duo will unlink which requires IT support intervention - frustrating for the end user.

A decent way to add security

4.0 last year

Comments: I think it's fine as I rather verify using the app then using a code as that takes a bit longer.

Pros:

I like that it gives an extra level of security to our accounts for school. The verification process is simple and quick.

Cons:

I think that it fails to recognize that I am the user logging in on the same computers. It's not a big issue though.

Duo Security is Duo Thumbs Up!

5.0 2 years ago

Comments: Overall, I can confidently navigate the digital landscape with Duo Push Login, knowing my information is secure. Their real-time verification gives me confidence in the protection of my online accounts.

Pros:

Using Duo Push Login has been a game-changer for enhancing my online security and providing peace of mind—there is versatility and compatibility across various platforms and devices. The flexibility it offers makes it convenient for both personal and professional use.

Cons:

Duo Push Login relies on having a compatible mobile device and an active internet connection. If I misplace or lose my device, or if it runs out of battery, I may need help accessing my accounts or be unable to access them all together.

Duo Security Review

Comments: I use DUO to sign in securely into my work computer. I haven't had any issues and I'm able to add as many computers and devices on there as I want.

Pros:

I like how quick my computer is able to communicate with the app on my smart phone in order to log me into my computer quickly and safely.

Cons:

It took some knowledge from my IT team in order for me to use the app properly. So some training is needed and it would be nice for a have quick help guide.

Super Easy MFA on Your App

5.0 2 years ago

Comments: Absolutely excellent because it does what it's supposed to do without issue.

Pros:

The thing I like the most about Duo Security is the ease of use. You simply download and utilize the app on your phone.

Cons:

This is simply another MFA application. It seems that different vendors have different preferences when it comes to MFA. I wish this was more consistent.

I liked the safety aspect of it the most. Duo security makes sure that no random device can get into your account, by making sure you approve on your phone.

Cons:

The only thing I did not like is sometimes it would lag.
