IAM users in the Amazon Web Services Management Console
IAM users may be able to change their password from the Amazon Web Services Management Console depending on their permissions. Otherwise, they must use an Amazon access portal. An IAM user is an identity within your Amazon account that's granted specific custom permissions. You're an IAM user if you didn't create the Amazon account and your administrator or help desk employee provided you your sign-in credentials that include an Amazon account ID or account alias, an IAM user name, and password. For more information, see IAM user in the Amazon Sign-In User Guide.
If you have permissions from the following policy: Amazon: Allows IAM users to change their own console password on the Security credentials page, you can change your password from the console. For more information, see How an IAM user changes their own password in the Amazon Identity and Access Management User Guide.
If you don't have the requisite permissions to change your password from the Amazon Web Services Management Console see, Resetting your Amazon IAM Identity Center user password in the Amazon IAM Identity Center User Guide.
