You can choose whether your connections can see your other connections.
LinkedIn is all about connections — and connections of connections. So it may seem counter-intuitive to hide your connections, but you may have good reasons for wanting to do so.
It all depends on how you are using LinkedIn, and how you view your own, and your connections' privacy.
People can conduct detailed searches that look solely through your connections using LinkedIn. So it's worth consideration.
The shortcut to this setting is at https://www.linkedin.com/mypreferences/d/settings/connections-visibility and there is a simple binary choice.
On means others can see your connections.
Off means only you can see your connections.
It's a binary choice. On or Off.
