Credentials for source authentication in Azure Purview

This article describes how you can create credentials in Azure Purview. These saved credentials let you quickly reuse and apply saved authentication information to your data source scans.



A credential is authentication information that Azure Purview can use to authenticate to your registered data sources. A credential object can be created for various types of authentication scenarios, such as Basic Authentication requiring username/password. Credential capture specific information required to authenticate, based on the chosen type of authentication method. Credentials use your existing Azure Key Vaults secrets for retrieving sensitive authentication information during the Credential creation process.
