The MFA champion

5.0 last month New

Pros:

The mobile app for Duo is extremely intuitive and easy to use. As we implemented the product in our organization we were impressed with how little hand-holding was required for our user-base to adapt to the new authentication workflow.

Cons:

This is going to seem nitpicky, and it is, but when the mobile application was recently re-written the location of the "accept/allow" login button switched from one side of the screen to the other. Users who frequently use the app very likely denied their login inadvertently.

Super easy to use mobile 2-factor authentication software

5.0 last month New

Comments: 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.

Duo Mobile

3.0 2 weeks ago New

Comments: Overall, because of these two experiences. I am genuinely going to look into an alternative option and preferably leave Duo as a personal preference. I love how secure it is but it's not okay to have a safety exit that doesn't work - like come on?

Pros:

No one will ever get in to your apps or info

Cons:

If you need to get in, you won't be able to. I had a phone stolen, and then unfortunately lost not long after I got a new phone. I had my back up codes saved when when the first one was stolen - did not let me into any of my apps and the worst part is - they give you 8-10 codes to use for a 'back up'. When the first one was stolen, I was extra safe and careful and then I sadly lost that one and I could, once again, not get into a single app using my back up codes.

Amazing Software for MFA authentication

5.0 2 months ago

Comments: Overall Duo has helped us improving device security and we were able to integrate with our Palo Alto Firewall devices and had pretty smooth experience.

Pros:

This worked pretty smoothly, when logging in the security devices such as firewalls, with duo we made sure no unauthorized users is logging into the devices with Multi Factor Authentication mechanism. With duo we simply were able to compliance with Zero Trust Model, no unauthorized users can make the changes on the system.

Cons:

They can work on their mobile application and make sure to improve the user experience, I feel bit delay while receiving the authentication request. Also on mobile app they can make it like only one finger touch is enough to authenticate the user. So less clicks can make the experience way better.

Duo Security Review

5.0 last month New

Comments: My overall experience with Duo Security is very good. It helps my organisation to secure the company resources or data which I can access via my credentials by adding the real-time authentication system. It helps them to secure the data if their members credentials get compromised.

Pros:

Multi-Factor Authentication is the best feature I like most. It makes my data or resources secure even if my credentials got compromised. Through their real-time authentication process, users can authenticate themselves from anywhere and then they can access their resources. It also helps an organisation secure its data or resources.

Cons:

As of now, I don't have anything which I don't like about this software.
