Sign in to savethumb|ATM user authenticating himself Authentication (from authentikos, "real, genuine", from αὐθέντης authentes, "author") is the act of proving an assertion, such as the identity of a computer system user. In contrast with identification, the act of indicating a person or thing's identity, authentication is the process of verifying that identity.
Authentication is the process of verifying that someone or something is genuinely who or what they claim to be, rather than just stating an identity. It matters because it allows systems like banks and computers to confirm your identity before granting you access to sensitive information or services.
