Two-Step Auth
I have a MacBook Air, however do not own any other Apple devices and am trying to set up two-step auth. I have set my mobile number up as a trusted to have my verification code sent via text. When I enter the code is does not accept it and asks me to enter it again. I have tried this on 4 seperate occasions after having a new code sent each time and I get locked out as it claims I have entered the incorrect code too many times.
Help!
MacBook Air, macOS High Sierra (10.13.3)
