To sign in to the AWS Management Console as an IAM user, you must provide your account ID or account alias in addition to your user name and password. When your administrator created your IAM user in the console, they should have provided you with your user name and the URL to your account sign-in page. That URL includes your account ID or account alias.
https://My_AWS_Account_ID.signin.aws.amazon.com/console/
You can also sign in at the following general sign-in endpoint and type your account ID or account alias manually:
https://console.aws.amazon.com/
For convenience, the AWS sign-in page uses a browser cookie to remember the IAM user name and account information. The next time the user goes to any page in the AWS Management Console, the console uses the cookie to redirect the user to the account sign-in page.
Note: IAM users can still use the URL link provided to them by their administrator to sign in to the AWS Management Console.
