Resetting the Passwords for Logging In to ECSs in a Batch

Function

This API is used to reset the passwords of the ECS management account, root or Administrator, in a batch.

Constraints

Before using this API, you must install the password reset plug-in. For instructions about how to download and install the password reset plug-in, see "Installing the One-Click Password Reset Plug-in on an ECS" in the Elastic Cloud Server User Guide.
After the request for resetting the password is issued, this API does not report an error if executing the script failed.
A new password takes effect after the ECS is started or restarted.
This API allows you to reset passwords when the target ECSs are running or stopped.

**Table 1** Parameter description

Request

Table 2 describes the request parameters.

**Table 2** Request parameters
Parameter	Type	Mandatory	Description
new_password	String	Yes	Specifies the new password. This field is mandatory only if dry_run is set to false. A new password must comply with the following rules: Contain 8 to 26 characters. Contains at least three of the following character types: uppercase letters, lowercase letters, digits, and special characters (!@%-_=+[]:./?). Cannot contain the username or the username spelled backwards. For a Windows ECS, the password cannot contain the username, the username spelled backwards, or more than two consecutive characters in the username.
dry_run	Boolean	No	Specifies whether to check the request and reset ECS passwords. true: indicates that only the password reset request is sent and the passwords for logging in to the ECSs will not be reset. Check items include mandatory parameters, request format, and service restrictions. If the check fails, the system returns an error. If the check result is as expected, the system properly responds. false: indicates that only the password reset request is sent and the passwords for logging in to the ECSs will be reset if the check result is as expected. The default value is false.
servers	Array of objects	Yes	Specifies the IDs of the target ECSs. For details, see Table 3.

**Table 3** **servers** field description
