Reset the administrator password for a server.

Important

The recommended REST commands to work with SQL Database are the Resource Manager based Azure SQL Database REST API. While there is no change to SQL Database, be aware that the classic deployment model command in this article is scheduled for deprecation on December 1, 2019. For a table providing links to the specific new commands you should use, see Operations for Azure SQL Databases.

Request

The Set Server Administrator Password request must be specified as follows:

Replace {subscriptionId} with your subscription ID.
Replace {serverName} with the name of the server to change the password.

Method	Request URI	HTTP Version
POST	https://management.core.windows.net:8443/{subscriptionId}/services/sqlservers/servers/{serverName}?op=ResetPassword	HTTP/1.1

If an operation returns success, the operation is complete and changes are effective immediately. If an operation fails because of a user error, no changes are applied. If there is a communication error or internal server error, you should check the status of the operation using List Servers (classic).

URI Parameters

None.

Request Headers

The following table describes the required and optional request headers:

Request Header	Description
x-ms-version	Required. Specifies the version of the operation to use for this request. This header should be set to 2012-03-01.
x-ms-client-request-id	Optional. Provides a client-generated, opaque value with a 1 KB character limit. Using this header is highly recommended for correlating client-side activities with requests received by the server.

Request Body

The format of the request body is as follows. Replace {myNewPassword} with your new password.

<?xml version="1.0" encoding="utf-8"?>  
<AdministratorLoginPassword xmlns="https://schemas.microsoft.com/sqlazure/2010/12/">{myNewPassword}</AdministratorLoginPassword>

The following table describes the elements in the request body:

Element Name	Description
AdministratorLoginPassword	The new administrator password for the server.

For more information about password requirements, see Password Policy

Response

The response includes an HTTP status code and a set of response headers.

Status Code

Response Headers

The response for this operation includes the following headers. The response may also include additional standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.

Response Header	Description
x-ms-request-id	A value that uniquely identifies a request made against the database management service. This request id is used for request tracking. If a failure occurs that requires the user to contact Microsoft Support, the request id should be provided to Microsoft to assist in tracking and resolving the failure for the request.

Response Body

None.

Example

The following console application resets the administrator password for a server.

Replace the following values:

{subscriptionId} – replace with the subscription identifier for your subscription.
{serverName} – replace with the name of the server.
{myNewPassword} – replace with the new password for the server.
{thumbprint} – replace with the thumbprint of a management certificate in your subscription.
