Duo Security Provides Authentication Services that are Easy to Implement

Verified reviewer

What they liked

The Duo Security App is an easy-to-download feature that integrates well with software solutions, multiple passwords, and is quick to access on a variety of devices

Room for improvement
  • It bugs me that we need this software solution, honestly
  • But I don't have a negative thing to say about Duo Security
  • I use it every day and it works

Awesome security app

Duo security has been easy to use and I would recommend to anyone who is looking to protect their passwords

What they liked

I enjoy how easy it is to review a request in security, it pops up as a notification, you approve and that’s that

Room for improvement

The thing I like least is that it isn’t as secure as other apps but Duo is still one of the better security apps

Indispensable - use it every day!

I use this daily for access to company website for updates and posting. It travels wherever I go and is lightning fast. Definitely recommend!

What they liked
  • Had another authentication app that went out of business and after much trial and error (and frustration) found Duo
  • Set up was easy and this app works perfectly every time
  • It's fast and easy to use
  • In my opinion, this app should be promoted/recommended to companies like GoDaddy when they're selling a website - this protection is so easy and simply invaluable
Room for improvement
  • Only one slight issue when I upgraded from iPhone 6 to iPhone 8 - it was a bit confusing to register the new device
  • At a certain point I thought I would have to disable the app and then it just started working - so I might suggest better documentation/walk through on changing devices

A security tool which you can rely for MFA

We were asked to implement MFA for cisco anyconnect and we found DUO could do this job as cisco did not have their own solution for MFA. Implementation took less than a day and it was super easy to use. License cost is also cheap. It supports Push notification, sms and even phone call. Support is very awesome as they respond quickly.

What they liked

Nice UI Easy to integrate with security products like cisco ASA Very cheap to implement if your organisation is looking for MFA Supports SAML Supports Radius

Room for improvement

I have not found any cons as such as the implementation was for MFA and it worked like a charm

Duo is the best

Fantastic experience overall. Helped several clients set the service up and gotten no complaints from them.

What they liked
  • Easy to use, and set up
  • Works really well and is easy to try and explain functionality to clients
Room for improvement
  • A necessary evil so to speak, when I'm in and out of systems that are protected via Duo it's annoying for me
  • That being said it's the nature of the beast

Duo Mobile Review

I enjoy using Duo Security everytime rather than using email confirmation

What they liked
  • It is quick to use and pops up even on my watch
Room for improvement
  • That I have to do it every time I log in, but no fault of the company

Frequent Duo Security User

Higher Education

What they liked
  • I like how seamless Duo Security integrates into my authentication process
  • The mobile app makes 2FA easy with a variety of methods to navigate authentication
Room for improvement
  • I don't have any cons about Duo Security from the end-user perspective
  • An initial concern was that 2FA would be excessive, but with how integrated mobile devices have become with everyday life, it only takes a few seconds to add an additional layer of security to protect my organization's data
