I am new to setting up Duo 2FA for Unix, yet new to Linux environment also. I have followed both log_duo and pam_duo instructions. What I am trying to figure out is how to implement Unix 2FA with an existing Duo User. I realized that when I “tested” pam_duo/login_duo, it generates creates a “root” user in the Duo Admin Panel. That is what I did not want. I would like Unix Duo to be carried thru an existing Duo User. Is there a way to divert this to an existing Duo User, such that it does not utilize a license?
Also is there a way to prevent from going to root@“username” after authenticating in Linux?
