I have created an SFTP storage account, and I would like to know if it is possible to change the default port 22 used for connection.

    Hi Gerald Ortiz Candela,

    It is not possible to change the default port 22 used for SFTP connections in an Azure Blob Storage account. SFTP is a platform-level service, and port 22 will remain open even if the SFTP account option is disabled. SFTP connections in Azure Blob Storage are designed to use port 22 for communication.
    Azure's SFTP service operates on a multi-tenant platform. Allowing each customer to customize the port would complicate the service architecture and could lead to security and management challenges.
    To manage costs effectively, it is advisable to disable the SFTP service when it is not in use. This helps prevent unnecessary charges associated with the service.

    Hi Gerald,

    Unfortunately there is no documented ability to change the default port used for Azure Storage SFTP. The SFTP service is multi-tenant platform service (as opposed to dedicated) so you can see how allowing each customer to have custom port would be difficult.

    As a reminder, to reduce cost it is best to disable SFTP when you are not actively using it. The reason is, you are charged every hour that SFTP is enabled, whether you use it or not.
