Unable to disable MFA

Would suggest try on below:

1. Try to Reconfigure MFA (if you still have access to the original device) If you still have access to the original MFA device:

• Sign in as root.
• Go to IAM > Users > Security Credentials.
• Choose Manage MFA and reconfigure or remove the device.

2. If You’ve Lost Access to the MFA Device You’ll need to submit an AWS support request to recover access. Here's how:

• Go to the AWS Support Center
• Choose Create case > Account and billing support
• Select Type: Account access
• In the description, explain:
• You’re the root user
• You’ve lost access to your MFA device
• You’ve verified your identity via email
• You’re unable to disable MFA or add a new device

Hi Zurab,

You can disable MFA on the root user (but it is not recommended as a best practice). To do this, you must first have a working MFA access. Since your current MFA access is not working, you can reach out to AWS Support and they can get this working again. You can do so using the MFA Support Form.

Thank you.
