AIM User - Cannot Change Payment VISA

Hello.

Is it possible to reset the root user's password and sign in using the steps in the document below?
https://docs.aws.amazon.com/IAM/latest/UserGuide/reset-root-password.html

If you don't know the email address associated with the root user, try searching for emails from AWS as described in the document below.
https://docs.aws.amazon.com/IAM/latest/UserGuide/troubleshooting_root-user.html

When you create an AWS account, you provide an email address and password. These are the credentials for the AWS account root user. If you aren't sure of the email address associated with your AWS account, search for messages sent from @signin.aws or @verify.signin.aws to any email address for your organization that might have been used to open the AWS account.
If you know the email address but no longer have access to the email, try to recover access to the email. Use one of the following options to regain access to your email:

• If you own the domain for the email address, you can restore a deleted email address. Alternatively, you can set up a catch-all for your email account. A catch-all collects all messages sent to email addresses that no longer exist in the mail server and redirects them to another email address.
• If the email address on the account is part of your corporate email system, we recommend that you contact your IT system administrators. They might be able to help you regain access to the email.

If you still cannot sign in, I recommend contacting AWS from the URL below.

Since our root user has passed, and his access with it, I cannot create a case. I cannot locate a support phone number and cannot get an email with the case (#3). I could also prove ownership to perform account recovery (#4) but only a root user can submit for their lost credentials. Please help. Thanks.

I understand you're in a difficult situation with limited access to your AWS account. Here are some suggestions that might help:

1. Root account access: The most straightforward solution would be to use the root account credentials (email and password) associated with the AWS account. The root user has full access to all AWS services and billing information. If you don't have these credentials, you may need to go through AWS account recovery processes.

2. IAM user access to billing: By default, IAM users don't have access to the AWS Billing console. This access needs to be explicitly enabled by the root user or an administrator. If this wasn't done, it explains why you can't change the payment method despite having permission to make monthly payments.

3. Contact AWS Support: Since you mentioned you can't create a support case due to lack of permissions, try reaching out to AWS through alternative channels. AWS provides general support contact options that don't require logging into the AWS console, such as phone support or email.

4. Account recovery: If you don't have root account access and can't reach AWS through other means, you might need to go through the account recovery process. This typically involves proving ownership of the account through various means.

5. Legal routes: In extreme cases where the account owner has passed away and no one else has root access, you might need to explore legal options to gain control of the AWS account, especially if it's critical for your business operations.

Remember, it's crucial to establish proper account access and management procedures to avoid such situations in the future. This includes setting up multiple administrators, securely storing root account credentials, and implementing a robust IAM strategy.

Given the sensitivity of this situation, it's advisable to contact AWS directly as soon as possible to explain your unique circumstances and seek their guidance on the best way to proceed.
