Detailed explanation-1: -Authentication is the process of determining whether someone or something is, in fact, who or what it says it is. Authentication technology provides access control for systems by checking to see if a user’s credentials match the credentials in a database of authorized users or in a data authentication server.

Detailed explanation-2: -Authentication is the process of determining if a user is who they say they are. Authentication is needed where a user must be verified in order to access a secure resource on a system. Form-based authentication is where a user is presented with a form allowing them to enter username and password credentials.

Detailed explanation-3: -Authentication factors can be classified into three groups: something you know: a password or personal identification number (PIN); something you have: a token, such as bank card; something you are: biometrics, such as fingerprints and voice recognition.

Detailed explanation-4: -Identification is the act of identifying a particular user, often through a username. Authentication is the proof of this user’s identity, which is commonly managed by entering a password. Only after a user has been properly identified and authenticated can they then be authorized access to systems or privileges.
