Unknown LUKS key slot enabled

This is my first time posting in any technical forum, but I’ll try to provide all of the relevant details up front. I installed Manjaro Cinnamon a week ago. During the installation, I enabled LUKS encryption for my system, just using the on screen prompts to do so. I only added a single password (I don’t even think there’s an option to add more). Now, however, I’m noticing 2 key slots are enabled when I run “sudo cryptsetup luksDum /dev/nvme0n1p2”. I verified that /dev/nvme0n1p2 was the right device by running “lsblk”. Key slot 0 was enabled and so was key slot 1. Its my understanding that there should be one key slot in use, just the one for the password I set. I know that I never added any other password or key file. Is this something I should be concerned about or am I just not understanding LUKS properly? Thanks.

This is normal. It is the way Calamares (the installer) sets LUKS encryption up.
