Apple ID trusted devices list is not available

Hello man1836,

Thanks for that info and choosing the Apple Support Communities. If I understand correctly, you are unable to see a list of trusted devices for your Apple ID. To do this, please follow these steps from this Apple resource on two-factor authentication.

You can view and manage a list of your trusted devices in the Devices section of your Apple ID account page.

Go to your Apple ID account page.

Sign in with your Apple ID.

Go to the Devices section.

The device list shows the devices that you're currently signed in to with your Apple ID. Select a device to view the model, serial number, and other useful information, including whether or not the device is trusted and can be used to receive Apple ID verification codes.

You can also remove a trusted device. Removing a trusted device will ensure that it can no longer display verification codes and that access to iCloud, and other Apple services on the device, is blocked until you sign in again with two-factor authentication. If you need to find or erase your device before you remove it from your trusted device list, you can use Find My iPhone.

Check your Apple ID device list to see where you're signed in

Cheers!
