AWS - 为现有 IAM 用户创建独立沙箱

您打开的控制台（在最后一个屏幕截图中）适用于 IAM 用户，但您正在尝试使用根账户凭证（基于您用于创建账户的电子邮件地址）登录。

It sounds like you want to sign in as an IAM User in the new account you have created. To do this need to create an IAM User in that account. You need to assume a role in the new account, or sign in with the root credentials (i.e. the email [email protected] and password), and then create the IAM User.

You can get to the root user sign in via the "Sign in using root user email" link below the sign in button in your screenshot. If you don't have the password for that root user (because you created it via AWS Organizations), you will need to do a reset password on it.

理想情况下，您不会为人类使用 IAM 用户，而是使用 SSO 来管理访问权限，但听起来您目前并未使用它，并且设置它超出了 StackOverflow 帖子的范围。AWS 提供 SSO 服务，如果您愿意，可以相对轻松地开始使用它。
