Google authenticator on C8
by Patrick DERWAEL 05 Jun '20

05 Jun '20

Hi folks I have installed Google authenticator on a few C8 boxes This is working fine on all of them except one... - google-authenticator is installed and the box is added to my Android app - /etc/pam.d/sshd contains auth sufficient pam_google_authenticator.so - /etc/ssh/sshd_config contains ChallengeResponseAuthentication yes - sshd restarted When logging in, I'm prompted with the password (i.e. no request OTP request) I have already uninstalled/reinstalled/rebooted and compared the config files across boxes... but I can't see what I have done wrong Any clue about what I could have missed? Thanks! -- Patrick Derwael
