Presentation: what is double authentication?
Two-factor identification, also known as double identification or authentication, helps to ensure your identity. This is to verify that it is not someone else who knows your password. Indeed, even if it is not necessary to do it, a lot of people use the same password everywhere (to a small variation close). This increases the risk of leakage of your password, even if it is not the only factor.
How it works ?
Everything will revolve around your trusted devices . As soon as a new device, browser or application connects with your username and password, your trusted devices receive a notification. This notification will indicate that “Your Apple ID has been used for a connection to a new device” by locating, more or less precisely, the connection. You can then Authorize the device, a code is provided. You will need to enter this new device.
By accepting it for the first time, the new iOS or macOS device will become a new trusted device. So yes, if you have a lot of Apple devices, when connecting a new one, it can sound everywhere!

Trusted devices, what is it?
Trusted devices are your security. It is safe for them that the notification for this receive the validation code will arrive. They can be Mac, iPhone, iPad, iPod touch. Apple TV and Apple Watch are devices that require the validation code, but can not be trusted devices.
