[!INCLUDEappliesto-ss-asdb-asdw-pdw-md]
A credential is a record that contains the authentication information (credentials) required to connect to a resource outside [!INCLUDEssNoVersion]. This information is used internally by [!INCLUDEssNoVersion]. Most credentials contain a Windows user name and password.
The information stored in a credential enables a user who has connected to [!INCLUDEssNoVersion] by way of [!INCLUDEssNoVersion] Authentication to access resources outside the server instance. When the external resource is Windows, the user is authenticated as the Windows user specified in the credential. A single credential can only be mapped to a single [!INCLUDEssNoVersion] login. And a [!INCLUDEssNoVersion] login can be mapped to only one credential.
For credentials that are stored in the master database and can be used throughout the instance of [!INCLUDEssNoVersion], see CREATE CREDENTIAL (Transact-SQL). For credentials used by a specific database, and portable with that database, see CREATE DATABASE SCOPED CREDENTIAL (Transact-SQL).
System credentials are created automatically and are associated with specific endpoints. Names for system credentials start with two hash signs (##).
For more information about credentials, see the sys.credentials and sys.database_scoped_credentials catalog views.
