how to I get authorization codes sent to my MacBook
I have a new MacBook. How do I get 3rd party authorization codes sent?
MacBook Pro 13″, macOS 10.15
I think you're going to have to ask the 3rd party app developer. Apple has no control on how such actions are actually invoked in a given app.
If you mean two-factor authorization, that's not 3rd party and the referring article is Apple's definitive instructions. What didn't work for you?
