Answer 2

Authentication is the method of deciding if someone or something is really who or what a person declares to be.

• Authentication offers device access control by testing to see whether a user's credentials fit those in an authenticated user database or a server for data authentication.
• Potential users are typically labeled with a user ID, and authentication is achieved when the user offers a token that carefully matches the user ID, such as a secure password.
• Authentication helps a business to maintain secure and stable networks by allowing only certified users or specific processes to view their protected files.
• These key resources include computer systems, comprehensive databases, extensive networks, active websites, and other applications or services dependent on the network.
