Running Ubuntu 18.04 Server, it seems pam will change the ownership of ~/.google_authenticator on login to root:USER

This means next time I try to login, I will be rejected. Changing the ownership of ~/.google_authenticator to USER:USER enables login again. Logging in with public key does not change the ownership.

Why is this happening and how can I avoid it.

Ok, it was not pam or google_authenticator that was the problem. My nfs mounted home directory got an updated configuration when upgrading to 18.04 that mapped all users to root.
