I want to set up 2 factor authentication by having a code texted to my mobile device but when I go to Settings/Security/Set-up-2-factor-authentication the only choices that it's showing me is either, 1. An authenticator App, or 2. A security Key. Why is there not an option to have a code texted to my mobile device? I don't want to use a 3rd party app. When I click on "Use a security key" nothing happens and it just take me back to the previous screen with the only choice of "3rd party security app" for an option. I have a personal account, is having a code texted to me not an option for people with personal accounts?
