Error: AWS MFA entity already exists error

The user cannot register an MFA device. IAM throws an error when a user attempts to assign a new MFA –

This entity is already in existence. There is already an MFADevice object with the same path and name. Before we may install a new virtual MFA device, please request that the administrator delete the previous one using the CLI or API.

When we, as administrators or users, visit the Amazon console, we can see that the Assigned MFA device is not allocated to that user.

Resolution for the error

As administrators, we must use AWS CLI to destroy the MFA device (even if it indicates it is not allocated).

To update the IAM user’s MFA, the performer must have IAM permission iam:DeleteVirtualMFADevice on the supplied resource.

Use the AWS CLI to execute the following command:

Run the command in the following:

• AWS account number is the account number where the user exists.
• username is the user’s IAM username.

This should clear the error warning and allow the user to register a new MFA device.
