This may be a dumb question, but I'm at a loss. I don't want to install another app if I can help it (authy..). If I don't install or log into Authy, will SMS be my default authenticator? If not, how can I enable SMS authentication?
Had this as a comment on my going live tweet. I have never spoken to this person, they do not follow me and have never been in my stream. Is it just me, or is this not right?
