Yubikey not initially working with MacOS client about keymaster HOT 15 CLOSED

This is a daily problem. I can recover without plugging in a second token by just re-running the Keymaster client. Usually on the third attempt it works.

from keymaster.

I'm also experiencing this when running keymaster on macOS. As @rgooch says, it tends to work on the third attempt.

from keymaster.

Now I seem to be getting this error instead of the read response error:

top of doU2fAuthenticate
manufacturer = "Yubico", product = "YubiKey OTP+FIDO+CCID", vid = 0x0407, pid = 0x1050
hid: privilege violation

from keymaster.

@prydonius : if you diable the OTP on the yubikey is this still an issue? (I think this would be a workaround)

from keymaster.

I think I disabled OTP mode and still experienced the problem.

I just disabled OTP, let's see if that improves anything

from keymaster.

@cviecco for the last couple of days I haven't been seeing these errors with OTP disabled. Will update this if I start seeing them again.

from keymaster.

I get this repeatedly

top of doU2fAuthenticate
manufacturer = "Yubico", product = "YubiKey OTP+FIDO+CCID", vid = 0x0407, pid = 0x1050
hid: privilege violation

Even though I enter the same password again and again, I am literally copy pasting the password to make sure that I am entering the right thing.
After 4 attempts it succeeds.

@prydonius do you still see the hid: privilege violation ?

from keymaster.

@nikunjy have you disabled OTP? After doing so, I no longer get either of the two errors reported here.

from keymaster.

I turned off OTP a long time ago and I've seen this problem occasionally.

from keymaster.

@rgooch : what version of yubikey do you use(paste the whole -checkDevices string) and what version of MacOS?

from keymaster.

@cviecco I have MacOS Catalina 10.15.4. Output:
`manufacturer = "FT", product = "U2F KB", vid = 0x0854, pid = 0x096e

manufacturer = "Yubico", product = "YubiKey FIDO+CCID", vid = 0x0406, pid = 0x1050`

from keymaster.

Currently the incidence of this is very low for me (I have OTP disabled and am running MacOS Catalina v10.15.4). I don't see a way to debug this without being able to reproduce it on-demand.

An idea.. test with using libfido2.. which is mady by yubico? https://github.com/keys-pub/go-libfido2
