Keypair authentication clarification

[purered]

When I want to set up keypair authentication, do I generate the keypair or does the person who needs to access the server generate the keypair and then they send me their public key?
I have read two different segments about key authentication and I'm confused.
Please advise.
Thanks

It's preferable that the client create the keypair and send the server the public key.

The server always uses the public key, regardless of who generates the private key, and the client needs the private key to connect to the server.
