Hereof, how does client certificate authentication work?

In server certificates, the client (browser) verifies the identity of the server. In client authentication, a server (website) makes a client generate a keypair for authentication purpose. The private key, the heart of an SSL certificate, is kept with the client instead of the server. It's stored in the browser.

Subsequently, question is, why do we use authentication certificates? Certificates replace the authentication portion of the interaction between the client and the server. Instead of requiring a user to send passwords across the network continually, single sign-on requires the user to enter the private-key database password once, without sending it across the network.
