No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

Fans call it easy to set up and a solid MFA layer, while others report it suddenly failing, stale releases with no PHP 8 support, and developers who don't answer.

    Love having this plugin because it adds an excellent layer of much needed security

    This used to be an awesome plugin. It offered seamless integration with Duo, blocking admin access to my site in the case of a password compromise or brute force attack. Sadly, it recently just stopped working. No Duo verification page, no errors in the logs; and the only way to get back into my site was ssh in and delete the plugin. Duo has apparently given up on the plugin, according to their github repo.They should just pull this plugin from listings.

    Best 2FA addon for WordPress – if it wasn’t so neglected. No updates for half a year, no PHP 8. Too bad. Could have been so great. Now it’s out. This topic was modified 3 years, 7 months ago by sotte. Reason: Correction

    I use Duo Security for many different apps and it works great. The negative reviews typically mean the person is not familiar with how to implement Duo Security correctly.

    The configuration and integration was super easy and I am using this for my Office 365 and VPN access as well. It’s great to be able to use a single MFA for multiple application.

    Its a solid plugin for allowing MFA to be integrated into your website. It allows you to use the DUO app on your phone, call your phone or enter a passcode. Make sure to setup a Duo account before installing and activating the app. I would also suggest that you “test” the login after install while still logged into your website on another computer as a just in case. I am not sure why people are dumping on this plugin. I only have a few users and it seems to work fine and I am thankful they provided this app to the store.

    Do not use. A Huge wordpress logo is at the top of the Duo login screen for all to see. It cannot be removed. Support are pretty useless saying “well that is how it works” yet you wont find that on any of their documentation. Also, it lets you use SMS only as an option yet your users see a weird message asking them to “choose an option” (there is only one). Plus the entire wording of their web prompt is simply confusing – a horrible UX which they charge $3 USD per use for! I wish I never heard of Duo – has cost me a fortune and now need to unwind it from this project. Trust me – Abort – if you are using the wordpress plugin.
