"Reliable Two-Factor Authentication with Hassle-Free Cross-Device Use"
5/5
What do you like best about Cisco Duo?

I really like how Cisco Duo works very smoothly across devices. It gives me notifications on my phone and while using wearables like my Apple Watch, making it very hassle-free. It's really valuable because I don't need to pull out my phone all the time, especially if I'm in a rush to log in to my computer during classes. The prompt through my Apple Watch is very easy, it's like a split second, and I can just confirm and verify my identity. The setup was very easy, so much so that I don't even remember how it was done. It didn't take me long at all to get it set up. Review collected by and hosted on G2.com.

"Versatile, Cross-Platform Authentication with Strong Admin Controls"
4.5/5
What do you like best about Cisco Duo?

Duo is versatile and can be used to work on multiple platforms easily. The management and administration functions allow for more consistent deployment and management of users and their authentication devices. It works well. Duo integrates fairly easily with any authentication provider. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

If a client is a Microsoft 365 or Azure heavy environment, they are likely to be covered by Microsoft Authenticator, which is a free product. Otherwise, I think Duo is essentially the gold standard. Review collected by and hosted on G2.com.

Sometimes when I verify myself, the token doesn't go through, and I'm not able to verify my identity. I have to redo it in such cases. Review collected by and hosted on G2.com.

"Easy, Reliable 2FA with Fast Prompts and Strong DevOps Access Control"
4.5/5

Dual authentication for logging in to our critical servers is easy and secure. It’s been reliable, and it gives us solid access control for our DevOps team. The mobile app is easy to use, and the notification prompts are much quicker than with any other 2FA tools I’ve used. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

When phone is discharged it troubles and other options are limited, even when replacing the account verification and request to IT team is bit complex. Review collected by and hosted on G2.com.

"Trusted, High-Class Security with DUO Push Multi-Factor Authentication"
5/5
What do you like best about Cisco Duo?

It has great security and compliance. It offers multi-factor authentication functionality. There is a user-friendly DUO Push mobile application that we can download on our smartphones, and whenever we need to authenticate on our websites, we can use the notification code to access them. With the DUO Push mobile app, there are also different methods available, such as phone calls, SMS codes, and token functionality. Overall, we can trust the DUO app, and it really helps keep our things secure. They will be having active customer support In case you stuck somewhere. It's easy for use and implementation in any handset it could be IOS or android. I need to use this daily as it's mandatory to authenticate while using the websites. Review collected by and hosted on G2.com.

What do you dislike about Cisco Duo?

There’s nothing to dislike, because they provide high-class security in this scam-filled world and help keep your things secure. Review collected by and hosted on G2.com.

"Integrates Seamlessly but Needs Better Third-Party Support"
3.5/5
What do you like best about Cisco Duo?

I like how Cisco Duo integrates well with the rest of the Cisco stack. It's useful for our setup since we're a Cisco shop, making the integration with firewall, network access, and so on quite convenient. Review collected by and hosted on G2.com.
