[ aws . iam ]



Changes the password for the specified IAM user.

IAM users can change their own passwords by calling change-password . For more information about modifying passwords, see Managing Passwords in the IAM User Guide .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--user-name <value>
[--password <value>]
[--password-reset-required | --no-password-reset-required]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--user-name (string)

The name of the user whose password you want to update.

This parameter allows (per its regex pattern ) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-

--password (string)

The new password for the specified IAM user.

The regex pattern used to validate this parameter is a string of characters consisting of the following:

  • Any printable ASCII character ranging from the space character (u0020) through the end of the ASCII character range
  • The printable characters in the Basic Latin and Latin-1 Supplement character set (through u00FF)
  • The special characters tab (u0009), line feed (u000A), and carriage return (u000D)

However, the format can be further restricted by the account administrator by setting a password policy on the AWS account. For more information, see update-account-password-policy .

--password-reset-required | --no-password-reset-required (boolean)

Allows this new password to be used only once by requiring the specified IAM user to set a new password on next sign-in.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To update the password for an IAM user

The following update-login-profile command creates a new password for the IAM user named Bob:

aws iam update-login-profile --user-name Bob --password <password>

To set a password policy for the account, use the update-account-password-policy command. If the new password violates the account password policy, the command returns a PasswordPolicyViolation error.

If the account password policy allows them to, IAM users can change their own passwords using the change-password command.

Store the password in a secure place. If the password is lost, it cannot be recovered, and you must create a new one using the create-login-profile command.

For more information, see Managing Passwords in the Using IAM guide.
