I got this after my wife's boyfriend hacked me he hacked my cell phone and my computer and stoled my peacock and Origins account but basically for the damage he did I had to pretty much had to replace every account I had I find this to be the perfect fix to my problem I now have this installed on my Google account and my Microsoft account, and I found it to also work with my Samsung account letting me know that no one can fully take over my account without the key

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

This app works great, but you will still need the desktop version to manage PIV certificates and slots. Version 7.0.0 added FIDO/Wealth management through the app, so it's now very easy for me to plug in my USB-C YubiKeys, see which resident FIDO keys are loaded and change PINs.

A great, open-source authenticator from a company focused on security and privacy. This app is non-invasive (requiring minimal permissions, only Camera for QR codes and NFC). Made to work for the physical key and is all done on the device, It is simple and does its job as intended, with no unnecessary features or advertisements. Highly recommended for its transparency and simplicity.

I have created passkeys on YubiKey 5 using passkeys.eu demo. I am able to log in to it using passkeys now. But YubiKey authenticator says there are no passkeys on my YubiKey. Why? Also NFC is flimsy on Android 14. What is happening?

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.

Got 2 one as a spare, waste of $s. Does not work on my phones, (Android - 13 OS), or Apple iPhone. When plugged into USB on Samsung ph, Keyboard disappears. Support say OS is the problem on Both phones¿. Any Free authenticator app, works on both, so it's the 5ci key which is bad, NFC is not seen, on either Ph: Save your Time & Money: Support is a Joke; AVIOD, Use any of the Many free app for your Wallet instead:🚫🗑
