This is a great article. Crisp and clear. Thank you so much
But I had this question on how this can be done that the verification code is asked again when sudo <command-name> is done or account is switched using su - <username>

Hello, @mail2mohitjoshi

You can try adding the following code to the /etc/pam.d/su file and then restart the ssh daemon.

  • auth required pam_google_authenticator.so

Hope that this helps!
