[ aws . iam ]



Changes the password of the IAM user who is calling this operation. The AWS account root user password is not affected by this operation.

To change the password for a different user, see UpdateLoginProfile . For more information about modifying passwords, see Managing Passwords in the IAM User Guide .

[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--old-password (string)

The IAM user’s current password.

--new-password (string)

The new password. The new password must conform to the AWS account’s password policy, if one exists.

The regex pattern that is used to validate this parameter is a string of characters. That string can include almost any printable ASCII character from the space (\u0020 ) through the end of the ASCII character range (\u00FF ). You can also include the tab (\u0009 ), line feed (\u000A ), and carriage return (\u000D ) characters. Any of these characters are valid in a password. However, many tools, such as the AWS Management Console, might restrict the ability to type certain characters because they have special meaning within that tool.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


To change the password for your IAM user

To change the password for your IAM user, we recommend using the --cli-input-json parameter to pass a JSON file that contains your old and new passwords. Using this method, you can use strong passwords with non-alphanumeric characters. It can be difficult to use passwords with non-alphanumeric characters when you pass them as command line parameters. To use the --cli-input-json parameter, start by using the change-password command with the --generate-cli-skeleton parameter, as in the following example:

aws iam change-password --generate-cli-skeleton > change-password.json

The previous command creates a JSON file called change-password.json that you can use to fill in your old and new passwords. For example, the file might look like this:

    "OldPassword": "3s0K_;xh4~8XXI",
    "NewPassword": "]35d/{pB9Fo9wJ"

Next, to change your password, use the change-password command again, this time passing the --cli-input-json parameter to specify your JSON file. The following change-password command uses the --cli-input-json parameter with a JSON file called change-password.json:

aws iam change-password --cli-input-json file://change-password.json

This command can be called by IAM users only. If this command is called using AWS account (root) credentials, the command returns an InvalidUserType error.
