Managing user passwords in Amazon

You can manage passwords for IAM users in your account. IAM users need passwords in order to access the Amazon Web Services Management Console. Users do not need passwords to access Amazon resources programmatically by using the Amazon CLI, Tools for Windows PowerShell, the Amazon SDKs or APIs. For those environments, you have the option of assigning IAM users access keys. However, there are other more secure alternatives to access keys that we recommend you consider first. For more information, see Amazon security credentials.
