The app has significantly improved its behavior over the last two years. If NFC is being iffy, the usb connection works wonders.

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.

Have used for years. Once had an issue, but the documentation available from YubiKey was sufficient to fix. I recommend this app and YubiKeys

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

Always open authenticator app when key is inserted is not working. This setting is not persistent or there's some other issue with Android 15. Also, why does Android say it's charging the key when it's inserted?

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 feature does not work, fortunately I bought the usb-c version, otherwise I could not use it in my phone
