I am trying to set-up MFA for an AWS user in the organization

Question

       {
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "Stmt1506369084151",
      "Action": [
        "iam:CreateVirtualMFADevice",
        "iam:EnableMFADevice",
        "iam:ListMFADevices",
        "iam:ResyncMFADevice"
      ],
      "Effect": "Allow",
      "Resource": "arn:aws:iam::account_#:user/user_name"
    }
  ]
}

I have this above policy which should enable users to set-up MFA by themselves. However, when I test this policy (by logging in as one of the users, I am not able to perform the desired action)

What am I missing in the policy snippet?

PS: The policy is attached to the user I try to log-in as. So this silly mistake is ruled out.

This works for me:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid": "AllowEnableResyncDeleteListMFA",
      "Effect": "Allow",
      "Action": [
        "iam:CreateVirtualMFADevice",
        "iam:EnableMFADevice",
        "iam:ResyncMFADevice",
        "iam:DeleteVirtualMFADevice"
      ],
      "Resource": [
        "arn:aws:iam::AWS_ACCOUNT_ID:mfa/${aws:username}",
        "arn:aws:iam::AWS_ACCOUNT_ID:user/${aws:username}"
      ]
    },
    {
      "Sid": "AllowDeactivateMFA",
      "Effect": "Allow",
      "Action": [
        "iam:DeactivateMFADevice"
      ],
      "Resource": [
        "arn:aws:iam::AWS_ACCOUNT_ID:mfa/${aws:username}",
        "arn:aws:iam::AWS_ACCOUNT_ID:user/${aws:username}"
      ],
      "Condition": {
        "Bool": {
          "aws:MultiFactorAuthPresent": true
        }
      }
    },
    {
      "Effect": "Allow",
      "Action": [
        "iam:ListMFADevices",
        "iam:ListVirtualMFADevices",
        "iam:ListUsers"
      ],
      "Resource": "*"
    }
  ]
}
