Business Account Access

Based on the error message you're seeing, it appears you're experiencing an authentication issue when trying to access your AWS account. This is a common problem that can occur for several reasons:

1. You might be attempting to log in with incorrect credentials or using the wrong login method for your account type.

2. If your organization uses AWS IAM Identity Center (formerly AWS Single Sign-On), you cannot log in using the standard AWS console login page with just the account ID. Instead, you need to use a specific access portal URL, typically in the format: https://d-xxxxxxxxxx.awsapps.com/start.

3. You may not have been properly assigned permissions to access the account through IAM Identity Center.

To resolve this issue:

• Verify you're using the correct sign-in process. If your organization uses IAM Identity Center, you should sign in through the access portal URL provided by your administrator.

• After authentication, you should see a list of AWS accounts you have access to. Select the appropriate account to access its AWS Management Console.

• Check with your AWS administrator to ensure your user has been properly assigned permissions and has been assigned to the account you're trying to access.

• If you're the account owner but have lost access, you may need to follow the account recovery process, which might involve verifying your identity with AWS Support.

• If you're using MFA (Multi-Factor Authentication), ensure you're entering the correct codes when prompted.

If you continue to have issues, contact your AWS administrator or AWS Support for personalized assistance with your account access problem.

Hello.

What IAM policy is attached to the user you are using to sign in to your AWS account?
Normally, if the IAM policy is configured appropriately, resources in the management console will be displayed correctly.
I recommend that you check the IAM policies attached to the user you are currently signing in with.
If you are accessing using the root user instead of an IAM user, there may be a problem with your AWS account, so I recommend contacting AWS Support.
