$iamUsers = Get-IAMUserList

foreach ($user in $iamUsers) {

Write-Host "User: $($user.UserName)"

$mfaDevices = Get-IAMMFADevice -UserName $user.UserName

if ($mfaDevices.Count -gt 0) {
Write-Host "MFA: enabled."
} else {
Write-Host "MFA: not enabled."
}

$accessKeys = Get-IAMAccessKey -UserName $username
$thresholdDate = (Get-Date).AddDays(-90)

foreach ($key in $accessKeys) {
if ($key.CreateDate -gt $thresholdDate) {
Write-Host "AccessKey: created within the last 90 days."
} else {
Write-Host "Access key: NOT created within the last 90 days."
