What is authentication?
The process of confirming that someone and something is, if fact, who or what it claims to be is known as authentication. By comparing a user's credentials to those stored in a database of authorised users or on a data authentication server, authentication technology controls access to systems. Authentication ensures secure systems, secure business processes, and secure corporate data. There are various types of authentication. Users are often assigned a user ID for identification purposes, and authentication takes place when the user enters credentials such a password that exactly matches their user ID. Single-factor authentication is the procedure of needing a user ID and password (SFA).
The company can also use authentication to help prevent people from exploiting or abusing the deal by requiring users to verify their identity with a government-issued ID.
