how to setup 2 step verification

That is the second time you helped me, Thank you very much,
Answer is I am trying to log into a vpn and i pressed 2step verification and what a mistake,
because I cannot get the google authenticator in my android phone to work for some reason?
In the mac I downloaded a 2FA and that also is not helping, so I had to finally log in with my apple ID.
now i hope to get 1password to be my authenticator if that is possible or else I have
to turn off 2 step. sincerely thanks
