What is "stingray identity" in my sign in log?
I've been having some issues with my laptop and my phone (running slow, random stuff appearing, etc...), so I reformatted my hard drive. After I set everything up I went to check my logs and found one for Protected iCloud Storage SignIn. Apparently I have stingray identities. What does this mean? I haven't signed in to iCloud since before the reformatting.
