i thought that it must be something like that but i was not sure if this is a technical limitation or a design decision.

however its a sad situation if one wants to use it this way for ssh logins. without being re-asked for the passphrase it would be a really sane solution IMHO.

That is because when you use the HID interface the CCID interface is ejected and then insert again subsequently.

Thus the OpenPGP applet is being re-initialized and you get prompted for pass-phrase again.

gpg-agent (using as ssh agent) ask passphrase again after...

2015-03-31T19:59:17+01:00

Hi,

i'm currently implementing yubikey support in OTPme (http://www.otpme.org). i got HOTP and TOPT (Yubico Authenticator) working without problems. i've also added my gpg keys to the yubikey neo and use them with gpg-agent as ssh-agent replacement.

now i stumbled about the issue that the gpg-agent wants me to re-enter my passphrase after i've pressed the button (slot 1) to send my HOTP OTP as a second factor at ssh login. i've checked the gpg-agent docs but haven't found anything related. so i want to ask if this is by (yubikey) design or an issue?

regards
