How do you authenticate a database user?
Passwords are one of the basic forms of authentication. A user must provide the correct password when establishing a connection to prevent unauthorized use of the database. In this way, users attempting to connect to a database can be authenticated by using information stored in that database.
Why we need to authenticate your account as users?
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.
