Yesterday I was studying and writing some texts in german. I closed my MBP and went watch some TV which made me forget about the german keyboard layout.
When I came back, my password wasn't being accepted at all. I double checked both shifts, caps lock, everything. (The keyboard layout wasn't being shown at the top)
I gave up and started looking online on ways to reset my password. I found out that anyone in possession of my Mac is able to easily reset my admin password even without knowing anything about me or my computer.
Is there a way to protect myself from this kind of "attack"?
