Text Messages Forwarding, shows 3 Macs.

[63W]

My iPhone is running latest iOS 13.6 and I never used beta iOS. When I go to Settings, Messages, Text Message Forwarding, it shows 3 Macs. I own and always owned 1 Mac computer. Its the only Mac computer I have ever owned.

Two weeks ago, 2nd Mac showed up in the settings. Two days ago, I formatted my MBA hard drive and reinstalled Catalina 10.15.6 from scratch and 3rd Mac showed up in the settings.

When I log in to my iCloud account (www.icloud.com), I go to settings and it shows 1 MBA. My iPhone, also shows 1 MBA (Mac) when I go to Settings, Apple ID and on the bottom it shows 1 MBA

Anyone know how to remove incorrect entries?

Ive attached images for reference.

Thanks in advance.

If you don’t sign out of iCloud on all your (i) devices before installing or reinstalling MacOS, it will duplicate your device. If you want to get rid of the 2 duplicates, you will need to change your Apple ID password.

Ohh, well that's a lot simpler than I would have guessed.

Thanks.
