They aren’t really designed to stop people from breaking in but rather to stop intrusive people that you talk to first before deciding to not let them in. With the chain, you can open the door a bit without allowing the person outside to force himself in without too much force, e.g. by blocking the door with your foot as the door can only be opened fully after closing it.
Advanced versions exist where if you put strain on the chain (mostly trying to push the door open from the outside) an alarm goes off.
Door chains are a funny concept to me. They look flimsy and not really suitable to keep anyone out.

LPT for ya: If you feel the need to protect yourself with a chain. Just don’t answer the door.
I don’t answer the door a lot. It’s works out just fine for me.
Yeah this in combo with a peephole solves every situation that a chain would be used for.
just make sure there’s no light immediately in front of the door, you don’t want people to know you’re standing there when you’re blocking the light.
There’s a version that’s more of a sliding bar that’s a lot more common nowadays. You see them in updated hotels.
