When should authentication be used?

Authentication is used by a server when the server needs to know exactly who is accessing their information or site. Authentication is used by a client when the client needs to know that the server is system it claims to be. In authentication, the user or computer has to prove its identity to the server or client.

Why do we need user authentication?

Authentication is important because it enables organizations to keep their networks secure by permitting only authenticated users (or processes) to access their protected resources, which may include computer systems, networks, databases, websites and other network-based applications or services.

How important is it to have a strong authentication process nowadays?

Strong authentication techniques build on that foundation. Strong authentication techniques combine two independent factors to confirm someone's identity and access. Compromising one leaves the other intact, so systems stay safe. And one element isn't ever reused, so it's nearly impossible to steal.
