Duo Secure Login
I thought it would end up being another cumbersome addition to accessing our work network but, it is actually very seamless once it is set up. I actually like it way better than many I have to use because it not a situation where I have to receive a text and then type it in on the computer. Simply login the way you normally do and your Duo app will just ask if you want to give permission and it literally gives you two boxes like in those letters kids would write to someone they like asking if they wanted to go steady and at the bottom would be two boxes and they would say check yes or no! It pops up automatically so no need to open the app first. It is actually that easy, way more easy than working up the courage to write a love letter asking someone to be you boyfriend or girlfriend much less giving it too them and going’s crazy waiting for it to be returned with the right box checked!

Non-existent Customer Service
Duo Mobile has no customer service support. I tried reaching out to Duo, but they snootily told me that they only work with Duo admins. Duo Mobile doesn't have logos or labels for many sites including Etsy, PayPal, Zappos, AAA, etc. Since I use the same email address for these accounts (which is tricky because many websites want you to use your email address for your user name. Can anyone say "brain dead"?), there is no way for me to know which account to use for which. For example, Duo Mobile does not have a logo or label for Etsy so my Etsy account shows up in Duo Mobile as "Third Party (user name)" with a pink circle with the first letter of my user name in it. What?! You mean to tell me that if I add an account that isn't already listed in the "Add account" list for your selecting convenience, I'm stuck with about 50 vague, nondescript, misleading "Third Party" logos or labels, most all with the same account name (aka user name which is also your email address)?! But, alas! No help is available. That's only for the very special Duo admins. And I didn't like the confusing initial set-up, where Duo Mobile asks you to save a brand-new password for app recovery (should anything happen to your phone, causing you to lose access to your Duo Mobile app) after the initial account set-up, making it look like they're asking you for the account password but it's really the app recovery password (which is also saved on your phone which makes me wonder how you're going to find that app recovery password. LOL They don't tell you that you're supposed to write the app recovery password down on a piece of paper and put it in your fire-proof safe that is bolted to the foundation of your house. LOL). Grade: F-minus!

Easy to use and effective for folks with brains
I don’t write reviews, but I felt compelled to do so here. I work in IT and since we adopted DUO, it has proven to be effective and easy to use for the vast majority of users. The one’s that have problems are generally the ones that don’t know how to operate their devices, or they take issue with our policies because they have poor personal information security. These are exactly the people that force companies to adopt stricter security in the first place. I cannot speak to the complaints of folks who choose to use it for accounts that are not connected to a work or school environment, but if you get a new phone or lose or damage your phone, of course it locks you out of everything. That’s what it’s designed to do.
