“Two-factor authentication that just works!”

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ConsWhen using an outdated version of the app, iOS push notifications just stop working without any error message or notification

“Great Security Software”

OverallOverall I have found Duo to be a great method for securing my data and private accounts. It has allowed me to make sure that sensitive information stays safe and away from prying eyes. It also gives me a sense of security financially, as some of my accounts secured by Duo are linked to payment portals.
ProsDuo is a great way to ensure that your electronic information and accounts are secure. I have used it as a student and I have found that it is reliable and provides peace of mind. It provides a dual authentication process so that no one can access my accounts but me. I like that any attempt to login to an account sends a notification instantly to my personal cell phone, allowing me to approve or deny access.
ConsI have experienced a few technical bugs with the software in my time using it, though they are relatively infrequent. There are times when Duo will push a login approval to my phone and then fail to allow me to log in to my profile even though I have accepted the push. It can also be confusing trying to figure out how to change settings with Duo. For example, if you have set the software to preferentially send an automatic push upon requesting login, it can be difficult to change that setting. There could be a little more clear direction regarding that process from Duo.

“Amazing Two-Factor Authenticator”

OverallGreat experience, user friendly and having this installed as an app on your Smartphone and not a physical key is amazing!
ProsYou get push notifications instantly, and you don't even need to get into the app, it can display a notification in your notifications bar (Android User) and you can approve/deny from there. Also, if by mistake you deny the login attempt, it gives you a "second chance" to get into the app itself and approve it.
ConsNothing to complain about this as of now, I was an RSA SecurID user and having to carry that small key was a nightmare. One thing I'd like is to get Duo Security for Windows, I work remotely and I could have that installed on my home's PC. What if I get my phone stolen and unable to buy a new one???

“Best Two Factor Identification App”

ProsI 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.
ConsEarlier 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 important”

ProsI have been introduced to Duo security the last year. The institute I am affiliated to insists on using the Duo security for access to emails and other sensitive data. Initially, I used to feel it is a little out of the way effort to have a two-factor authentication via Duo Security. But lately, I have it is a rather important safeguard for sensitive data, emails, etc. It adds another level of protection. With technological advancement stealing important information from the internet is a child's play. Using Duo security gives the users benefit of knowing when their emails or secured accounts are accessed (at least it does that for me). Besides, two-factor authentication allows me to restrict suspicious users from logging on.
ConsDon't know but can the Duo also work by pushing login request via email? That would mean I wouldn't need to have my mobile phone next to me 24x7.
