ResetInstancesPassword

Last updated: 2024-10-22 19:33:02

    1. API Description

    Domain name for API request: cvm.tencentcloudapi.com.

    This API is used to reset the password of the operating system instances to a user-specified password.

    • To modify the password of the administrator account: the name of the administrator account varies with the operating system. In Windows, it is Administrator; in Ubuntu, it is ubuntu; in Linux, it is root.
    • To reset the password of a running instance, you need to set the parameter ForceStop to True for a forced shutdown. If not, only passwords of stopped instances can be reset.
    • Batch operations are supported. You can reset the passwords of up to 100 instances to the same value once.
    • You can call the DescribeInstances API and find the result of the operation in the response parameter LatestOperationState. If the value is SUCCESS, the operation is successful.

    A maximum of 10 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.

    2. Input Parameters

    The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.

    Region Yes String Common Params. For more information, please see the list of regions supported by the product.
    InstanceIds.N Yes Array of String Instance ID(s). To obtain the instance IDs, you can call DescribeInstances and look for InstanceId in the response. The maximum number of instances in each request is 100.
    Password Yes String Login password of the instance. The password requirements vary among different operating systems:
    For a Linux instance, the password must be 8 to 30 characters in length; password with more than 12 characters is recommended. It cannot begin with "/", and must contain at least one character from three of the following categories:
  • Lowercase letters: [a-z]
  • Uppercase letters: [A-Z]

    For a Windows CVM, the password must be 12 to 30 characters in length. It cannot begin with "/" or contain a username. It must contain at least one character from three of the following categories:
  • Lowercase letters: [a-z]
  • Uppercase letters: [A-Z]

  • If the specified instances include both Linux and Windows instances, you will need to follow the password requirements for Windows instances.
    		•
    UserName No String Username of the instance operating system for which the password needs to be reset. This parameter is limited to 64 characters.
    ForceStop No Boolean Whether to force shut down a running instances. It is recommended to manually shut down a running instance before resetting the user password. Valid values:

  • FALSE: do not force shut down an instance after a normal shutdown fails.

    Default value: FALSE.

    A forced shutdown is similar to switching off the power of a physical computer. It may cause data loss or file system corruption. Be sure to only force shut down a CVM when it cannot be shut down normally.
