   Field Name	Description
   Provide a name for this account. e.g. "MyAccount"	A short, descriptive name that helps you re-use this account in future.
   Access Type	This field governs the type of authentication you choose to connect to your Azure Blob. Note: You can select Azure AD, Shared Key, or Shared Access Signatures as the Access Type. Based on your selection, the next field will ask you for the required input (Id, Key, or Signature) to proceed. For example, if you select Azure AD as the Access Type, the next field in the form will be Tenant Id where you’d need to enter the Tenant Id of your Azure Blob account. You can also use HashiCorp Vault to fetch the Shared Key and Shared Access Signatures secrets. Before you use HashiCorp Vault, ensure that you have cleared the browser cache. If you ever change the secrets for this activity in HashiCorp Vault, ensure that you have cleared the cached secrets to bring the change into effect. Each secret is maintained as a key-value pair in Hashicorp Vault. Enter the variable in the following format in the field for which you want to fetch the secret from Vault:  ${Vault:<Key1>} Where, <Key1> is the key in Hashicorp Vault that is defined for the field for which you want to fetch the secrets.  For example, you need to enter ${Vault:SharedAccess.Signatures} in the Shared Access Signatures field, if you have defined SharedAccess.Signatures as the key for this field in the Vault. For more details refer to this page. You can also enter the values manually. You can select one of the following Access Types: Azure AD – This option facilitates OAuth based authentication and the user experience will be the same as the other OAuth apps. Once you select Azure AD as Access Type, you’ll require the Tenant Id to enter in the next field. To know how to get the Tenant Id refer to this page in the Microsoft Azure documentation. After clicking Continue, the user would need to enter the Azure credentials in a new window. Shared Key – Facilitates non-OAuth based authentication.
