IAM Debugging
MFADevice entity at the same path and name already exists⚑
It happens when a user receives an error while creating her MFA authentication.
To solve it:
List the existing MFA physical or virtual devices
aws iam list-mfa-devices
aws iam list-virtual-mfa-devices
Delete the conflictive one
aws iam delete-virtual-mfa-device --serial-number {{ mfa_arn }}
