My very first key was not a yubiCO . It was a cheaper T100 version I bought on eBay which was nothing in comparison and on top of that it rusted it broke and that's how I ended up needing a yubikey is 100 times better I'm telling you just pay the extra 20 or 30 bucks and buy the yubikey it does to factor it remembers your logins and on top of that it lasts long sure you can get a cheap T100 on eBay but it won't last as much a yubikey my yubikey still works today and the T100 broke

NFC on Android works - you need to be touching the button at the same time as holding the yubi nfc device to your phone. I figured this out after reading another review mentioning tapping the nfc. Baffling that yubico don't update this app or provide any gaddamn support at all. The authenticator app doesn't have a PIN/fingerprint lock option which would be good for leaving a nano in the usb port else if your phone is nicked they have free reign.

Terrible app that doesn't recognize the YubiKey over NFC half of the time. And I hate the UI update. You now have to click one more button the get the code. Please make the app less fancy. It just needs to work. Edit: This is not an issue for customer support. This is an issue for the developers. Simply reverting to the old app is the best. The new app sucks.

NFC does not work with new smartphone. My older smartphone is getting old and the battery starts giving up too early. So I got new one. Yubikey 5 NFC is still working with the old smartphone, but NOT with the new smartphone. Although I already try to connect the YubiKey 5 NFC through USB once with the new smartphone (I was thinking that they might need a more secure intro each other at least once), the YubiKey 5 NFC still can NOT work through the NFC tap.

So far so good!, have had once or twice communication error, either try again or restart app, not a huge deal, alot better having the codes stored on hardware where Fido2 isnt supported. Remember folks, anywhere you have 2fa enabled, print Off or write down your backup codes incase you cant use your key or codes. All in all happy so far with the app, running it on s10 plus on android 10

I like Yubico. It's very easy to use. But, I have an issue. In the past when I plugged my key to my phone, the app would auto appear. Now I have to open app manually and then insert key. If I do it key first and app after, when touching the key, does nothing. Is this a known bug? Help me out here please. Thanks... 3 stars only until problem fixed. 5 after...

TLDR: APP FINE. PROBLEM IS THE YUBIKEY. The NFC function works fine on most devices; if not, get a USB adapter for a few bucks so you can plug it in. Problem is that my Yubikey filled up far too quickly.. maybe when they designed it, 25 slots seemed a lot, like 640K of memory once did in PC's. But in 2022, that's nothing. Now shopping for competitor devices with more slots. PS: Buy 2 devices, keep 2nd in safe as backup

Please fire the manager who decided to "redesign the interface". Getting a code used to be quick and easy, now it's scroll, search, waste time and click. Bring back the old interface. Efficiency, gentlemen! EDIT: New version also breaks the ability to scan QR code to backup key. "Name already exists". Do you test your releases?

Don't upgrade. It still does exactly what it claims but the previous version was leaps and bounds better. The accessibility of this version has jumped ship - the dark mode is grey, not black and the codes are half the size which may cause problems for visually impaired people. There are far fewer settings, many I use. I'd hoped this version would bring the ability to sort accounts but you can still favourite some which helps. I'm rolling back to version 2.2 if I can. This is a backwards step.

Very useful as it is! One function that's missing from the desktop version that I'd appreciate, the ability to program what the two OTP slots do.

Mobile app istotal trash. While the key itself and the desktop app work as intended, I couldn't get any of the accounts that are working with the key /desktop app, to even get acknowledged by the mobile app. While the QR code was scanned and is showing/populating its info in the app, absolutely nothing happens when prompted to touch the key in order to save it. Total waste of time.

Added about 30 TOTP codes and after doing so, suddenly started to get the error: Error In Yubikey Communication. I've tried to uninstall and reinstall, and even tried this app on multiple phones. What's worse is even on the Windows app from Yubico the codes are gone. Fortunately I had made a backup when I realized how ugly the app was, fearing bad development. Sad waste of time. Hope they fix this issue soon.

A while ago an update added an additional tap to copy a code to clipboard. I thought I would've gotten used to it but it continues to cause me friction. I used to be able to tap on a code and it would directly copy to the clipboard. An update removed that functionality and replaced it with a menu selection which requires a second tap to copy the code to the clipboard. The additional tap is frustrating when fighting with the clock before the code expires. Please reduce the number of taps!

Yubikey 5 NFC isn't working with Pixel 2 XL running Android 9 (Security Patch Level: October 5, 2018). Its working fine on my Nexus 9 tablet running Andrdoid 7.1.1 (Security Patch Level: October 5, 2017). I suspect something is wrong with the application and Android 9. I hope its fixed soon. I'm really excited to use my Yubikey. If I put it right on top of the finger print scanner, it seems to be working better. Still not perfect.

For a long time I was trying to figure out how to get my NFC key to work with my phone. I'd tap it and it'd ask which browser to use and then would open an unhelpful web page. Finally, I discovered this app and thought it might be the solution to using NFC on mobile. Nope! Tap is detected but nothing happens. Finally after a few taps it gives "Error in Yubikey communication". Sigh.

The best authenticator hands down. I don't know what other people are experiencing, but as for myself, it is the most reliable and safest way to do 2FA. By reducing the need of an authenticator to depend on a email, password, and/or phone number to retrieve data, you simply allow "the token" to have a "token"( a key), making it super secure. Plus the data is not stored on the phone, making it brilliant if you lose your phone. Avoiding the hastle of changing accounts and passwords. A+++

Recent updates have made the app completely useless. I have a Yubikey 5 NFC, which I can no longer use with this app. Tapping the key summons the app just fine, but no matter what I do from there, getting a code is impossible. The "finger on the dot" buttons to absolutely nothing, the green refresh button prompts me to tap but still grants no code. Edit: turning on "bypass touch requirement" at least gets me codes now, but come on. Test these things, please?

I got completely confused by the UI in this update. You can still get your hardware key via NFC, but the app itself does you no favors in explaining how or giving visual feedback on when it does it. You have to change the settings under "On YubiKey NFC tap" from "Launch Yubico Authenticator" to "Copy OTP to clipboard" or "Launch app and copy OTP". It copies to the clipboard while providing no visuals. Seeing "No accounts" is confusing. This is operation is not OTP, that's misleading.

This works great. It initially threw me because saved credentials only show up when you tap the key with your phone. They really need better documentation of how to use this- I think people are marking it down because they are confused about how this is supposed to work. I think it's pretty cool though.

Except for one glaring deficiency, I really like it. The problem is with the UI ... I can't figure out how to replace an entry. (... or delete it so I can add the new one back in.) It's such an obvious use case, it couldn't have been missed in development, so I figure I must just not be seeing it in the UI.
