It's great. **What do you dislike about Cisco Duo?** The login requests time out pretty quickly. I know this is important for security purposes, but sometimes you get distracted or something else comes up and then you have to start the whole process all over again. **Recommendations to others considering Cisco Duo:** yes! **What problems is Cisco Duo solving and how is that benefiting you?** We use this to manage a single sign-on with just about every website and application we use at work.

If I have to use it, at least it's the best to do the job **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in E-Learning | Enterprise (> 1000 emp.) **Reviewed Date:** April 02, 2019 **What do you like best about Cisco Duo?** That it's fairly easy. I'm dislike that my school has switched to multi-factor authentication, however if we HAVE to use it, I prefer it to, say, Amazon, where you have to be texted. **What do you dislike about Cisco Duo?** I dislike that if I don't have my phone or passcode, I can't get in to websites I need. I also dislike that some sites require duo, but don't actually have the duo confirmation page come up (you have to use your phone or change the password to include the passcode). **Recommendations to others considering Cisco Duo:** If you need multi-factor authentication, this is the best possible product to do it. **What problems is Cisco Duo solving and how is that benefiting you?** Protecting valuable data on education as well as billing. ### 9.

Convenient extra layer of security **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Hospital & Health Care | Enterprise (> 1000 emp.) **Reviewed Date:** December 07, 2018 **What do you like best about Cisco Duo?** Compared to other two-factor authentication platforms I’ve used, this one is more reliable and feature-rich. Every time I request a sign in, I immediately get a notifcation on my phone, whether the app is open or not—no delays or inconsistencies. I also like the multiple options for verifying a sign in. I mostly use “Push,” but I have occasional used “Passcode,” and that’s equally reliable if slightly less convenient. Finally, my initally registration with Duo took mere milliseconds, thanks to the option to scan a barcode provided by my company to add an account. **What do you dislike about Cisco Duo?** When my phone broke, I was unable to access my accounts because I didn’t have access to that device to verify my sign ins. Luckily, my replacement phone has the same number, and I got the replacement quickly enough to minimize my time without access, but I wish Duo would come up with a solution for registering a back up device to avoid this problem. Also, if my phone were stolen, I’m not sure how to remotely de-register it with Duo, so having a blurb about that in their “User Guide” that comes with the app might be nice. **Recommendations to others considering Cisco Duo:** It’s the best dual-authentication platform in terms of user experience that I’ve used. **What problems is Cisco Duo solving and how is that benefiting you?** Duo allows me to have another layer to ensure the security of patient information, further preventing possible breaches of health data beyond usernames, passwords, and other access restrictions. The Push notifications are convenient in that I don’t have to enter an extra passcode and would immediately be notified whether someone else were trying to access my accounts, even if the app were closed. ### 12. love the security **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Health, Wellness and Fitness | Mid-Market (51-1000 emp.) **Reviewed Date:** September 29, 2019 **What do you like best about Cisco Duo?** love the way i can secure things with it. we use at work and it's wonderful. **What do you dislike about Cisco Duo?** I think that it is actually perfect.

Full feature 2FA Provider **Rating:** 4.5/5.0 stars **Reviewed by:** Thomas S. | Chief Technology Officer, Mid-Market (51-1000 emp.) **Reviewed Date:** April 24, 2018 **What do you like best about Cisco Duo?** I like how well different integration topics are covered by Duo's knowledge base. **What do you dislike about Cisco Duo?** Automated emails from Duo's billing and sales team seem to go to junkmail because they use some service.
