How to go into my iCloud account

Hey There 🙋🏽‍♂️

For that matter please first:

1. Sign in to appleid.apple.com, then select Devices.
2. Click the device to see its details, then click "Remove from account."
3. Review the message that appears.
4. Click again to confirm that you want to remove the device.

You can also have a look in here if you want to permanently delete a device:

Hope this could help.
