Security - (Identity+Authenticator=Credential)
Identity is typically an account’s user name such as:
- the Security Accounts Manager (SAM) account name
- or the User Principal Name (UPN).
To prove their identity, a secret information called the authenticator must be provided. An authenticator can take various forms depending on the authentication protocol and method. The combination of an identity and an authenticator is called an authentication credential.
Credentials are electronic information that are used to verify an identity.
