"The act of proving an assertion, such as the identity of a computer system user."
The process of verifying the identity of a user or system.
Password-Based Authentication: A method of authentication in which a user must enter a password to confirm their identity.
Two-factor Authentication: More secure method of authentication that requires the user to provide a second factor, such as a code sent to their phone or a security token.
Single-Sign-On: Allows a user to log in once and access many different applications or services without having to enter their credentials repeatedly.
OAuth/OpenID Connect: Standards that provide a way for users to grant third-party applications access to their accounts without sharing their passwords.
SAML: A standard for exchanging authentication and authorization data between parties, often used in enterprise environments.
JWT: A JSON-based format for creating and sending claims between parties, often used for secure communication.
Identity Federation: A mechanism that allows different organizations to share user authentication and authorization information.
Active Directory: A centralized database that stores user account information and authentication data, often used in enterprise environments.
LDAP: A protocol used to manage and access directory information, often used in combination with Active Directory.
Biometric Authentication: A method of authentication that uses physical characteristics such as fingerprints or facial recognition.
Multi-Factor Authentication: A combination of two or more methods of authentication to provide stronger security.
Access Control: The process of granting or denying access to resources based on a user's identity and permissions.
Authorization: The process of determining what level of access or privileges a user has to specific resources.
Kerberos: A protocol used to authenticate users in a network environment, often used in conjunction with Active Directory.
Public-Key Cryptography: The use of asymmetric cryptography to verify a user's identity or encrypt data.
Password authentication: User provides a unique combination of characters to authenticate.
Biometric authentication: Authentication using physical traits such as fingerprints, face, iris, etc.
Two-factor authentication: Also known as 2FA, it requires two methods to validate identity. For example, a password and a fingerprint.
Multi-factor authentication: Similar to 2FA, but involves three or more methods of authentication.
Certificate-based authentication: Authentication based on digital certificates issued by trusted third parties.
One-time password (OTP) authentication: Password generated for a single use, typically delivered through SMS or mobile apps.
Public key infrastructure (PKI) authentication: Uses a public key infrastructure certificate to authenticate users.
Smart card authentication: Authentication using a smart card, similar to a credit card with a chip.
Risk-based authentication: Analyzes user behavior and location to determine if additional authentication is necessary.
Token-based authentication: Authentication using a physical token that generates a unique value for each transaction.
SAML-based authentication: Authentication using a security assertion markup language (SAML) assertion.
OAuth-based authentication: Allows users to authenticate using credentials from a third-party provider, such as Google or Facebook.
OpenID-based authentication: Allows users to authenticate using credentials from an OpenID provider.
Windows integrated authentication: Authentication using a user's Windows credentials.
"Authentication (from Greek: αὐθεντικός authentikos, 'real, genuine', from αὐθέντης authentes, 'author')."
"In contrast with identification, the act of indicating a person or thing's identity, authentication is the process of verifying that identity."
"It might involve validating personal identity documents."

"Determining the age of an artifact by carbon dating."
"Ensuring that a product or document is not counterfeit."
