User reviews

Makes verification fun

I can’t get enough!

Fast and effective

As an end user, I greatly prefer Duo over other authenticators because validation is always instant, easy and effective.

Unnecessary to solicit reviews.

DUO mobile has asked me to submit a review.

If it weren't for the fact that my job work requires me to use two-factor authentication I wouldn't use this at all.

I am simply reviewing this software in order to stop these pop-up requests for APP review from continuing to interfere with my work.

DUO: would you rather have 1 star reviews or no review at all?

Easy to use

I e been using DUO and it’s just been a breeze so far

I lost all my accounts

I got my phone reset from factory and the duo app got resent and I lost access to the codes and back up codes. There was no way to recover the account and I lost email and social media accounts. It’s TERRIBLE that they don’t have a backup plan when these things happen and it’s pretty normal that sometime people lost all information.
