Accountsd wants to use the "Local Items" Keychain
Problem
Today, when I was looking through my keychain access (no idea why), I found that the Login and Local Items keychain was unlocked. So of course, I proceeded to locking it. Immediately after, a popup came up with this: "accountsd wants to use the Local Items/Login keychain". Then it asked for my password. This made me feel suspicious because I recently downloaded something off of the Internet and I am paranoid that it might be malware. I feel like the Login and Local Items keychains have been both unlocked for some time now because otherwise I would have experienced this problem sooner.
Here are some details about my mac:
