Apple securely stores unique identifiers like serial numbers and iPhone EID numbers to recognize trusted devices.
Additionally, some screenshots of the iPhone configuration are included below for reference.

Trusted devices are Apple devices (iPhone, iPad, Mac, etc.)
that youve already signed in to with your Apple ID.
Once signed in, these devices can receive verification codes to complete 2FA.
