Hello,
how can I select by default the app to open when I tap with my yubikey my phone? So far I failed trying to do so.

Thanks

gonzalo you need be more specific.
What's your use case?
But I will try to help you.

Yubico offers two great user experiences on Android employing a simple tap for NFC or a physical connection with USB.

Native Support

Natively, the following features of the YubiKey are supported on Android over USB.

OTP* (Yubico OTP, Static Password, and OATH-HOTP)
U2F (requires Google Authenticator to be installed)

The following features are not supported natively by Android over USB.

HMAC-SHA1 Challenge-Response*
PIV
OpenPGP**

*Native OTP support excludes HMAC-SHA1 Challenge-Response credentials
**The YubiKey's OpenPGP feature can be used over USB or NFC with third-party application OpenKeyChain app, which is available on Google Play

Extended Support via SDK

Android apps can add support for the following YubiKey features over both USB and NFC by incorporating our SDK for Android.

OTP (includes Yubico OTP, Static Password, and OATH-HOTP)
OATH (Yubico Authenticator)
PIV

Basically, when I tap with my yubikey on my phone, instead of automatically open the Yubico Authenticator it gave me the option, which I select as "always" and yet every single time I tap still give me option to select the app.

Does the Yubikey work without Google Services on GOS?

dirksche For certain features, yes. And with Google Play Services installed, it works with all features of the yubikey.

With Onlykey nothing works without Google Services beside the build in Password Manager. But no webauthn no passkeys....

I don't know of any applications that will allow webauthn to work without Google Play Services. Most delegate FIDO related tasks to Google.
