Cant turn off two-factor authentication
I just rebooted my macbook pro to factory settings. Before I did this I had two-factor authentication turned on.
I now have the oldest OS and I want to download Mojave. When trying to download Mojave I have to use two-factor authentication, and thats fine, but my appstore app on my Macbook is to old. So when Im getting a notification on my phone, and Im going to write in the 6 numbers on my macbook, the 6 lines dosent show up. I cant turn it off in settings either, because the OS is to old. Cant turn it off on my phone either. The "turn off two-factor authentication" dosent pop up.
Please help.
Macbook (2015 or later)
