# ChangePassword
<a name="API_ChangePassword"></a>

Changes the password of the IAM user who is calling this operation. This operation can be performed using the Amazon CLI, the Amazon API, or the **My Security Credentials** page in the Amazon Web Services Management Console. The Amazon Web Services account root user password is not affected by this operation.

Use [UpdateLoginProfile](https://docs.amazonaws.cn/IAM/latest/APIReference/API_UpdateLoginProfile.html) to use the Amazon CLI, the Amazon API, or the **Users** page in the IAM console to change the password for any IAM user. For more information about modifying passwords, see [Managing passwords](https://docs.amazonaws.cn/IAM/latest/UserGuide/Using_ManagingLogins.html) in the *IAM User Guide*.

## Request Parameters
<a name="API_ChangePassword_RequestParameters"></a>

 For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

 ** NewPassword **   
The new password. The new password must conform to the Amazon Web Services account's password policy, if one exists.  
The [regex pattern](http://wikipedia.org/wiki/regex) 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 Amazon Web Services Management Console, might restrict the ability to type certain characters because they have special meaning within that tool.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 128.  
Pattern: `[\u0009\u000A\u000D\u0020-\u00FF]+`

 ** OldPassword **   
The IAM user's current password.
