Stranger danger

My almost 2 year old is legit terrified of anyone and everyone. Like literally. In these times it’s not a bad thing but at the same time it’s so extreme and unhealthy. Like not even family and friends he’s seen multiple times. Idk if I should force him to get used to it or if he will outgrow it. I tell him it’s okay but he shuts down and freaks out. I wonder if I made him scared of people or he’s naturally like that or if it’s bc he’s not constantly around others. Anyone else like this. Things that can help?
