SQL Server Credential Password and Secret Difference?
What is the difference between SQL Server secret and password for credentials


A credential has three fields: Name, Identity, and Secret.  Depending on what the credential is used for the fields are used differently.  For instance if the credential is used to store a Windows identity, the user name goes in Identity, and the password goes in Secret.  If it's used to store the access credentials for Azure blob storage, a SAS token is stored in Secret, etc.
