Trying to Deploy VM using ARM Template

Hey guys. I'm trying to deploy a VM using the ARM template. These are the commands below that was run in PowerShell.

echo "New-AzResourceGroupDeployment -Name "dplisvvm$postfix" -ResourceGroupName "$rgName" -TemplateFile "VHDtoImage.json" -userStorageAccountName "$storageaccount" -dnsNameForPublicIP "$vmName" -subscriptionId "$mysubid" -location "$location" -vmName "$vmName" -vaultName "$kvname" -vaultResourceGroup "$rgName" -certificateUrl https://vaulto.vault.azure.net/keys/Arthur/cf9ba64e6bb24adfa943ed9d5ab72ce0.Id -vhdUrl "$vhdUrl" -vmSize "Standard\_A2" -publicIPAddressName "myPublicIP1" -virtualNetworkName "myVNET1" -nicName "myNIC1" -adminUserName "Aruzki19" -adminPassword "Antwaynio97101#"

New-AzResourceGroupDeployment -Name "dplisvvm$postfix" -ResourceGroupName "$rgName" -TemplateFile "VHDtoImage.json" -userStorageAccountName "$storageaccount" -dnsNameForPublicIP "$vmName" -subscriptionId "$mysubid" -location "$location" -vmName "$vmName" -vaultName "$kvname" -vaultResourceGroup "$rgName" -certificateUrl https://vaulto.vault.azure.net/keys/Arthur/cf9ba64e6bb24adfa943ed9d5ab72ce0.Id -vhdUrl "$vhdUrl" -vmSize "Standard\_A2" -publicIPAddressName "myPublicIP1" -virtualNetworkName "myVNET1" -nicName "myNIC1" -adminUserName "Aruzki19" -adminPassword "Antwaynio97101#"

And below is the error I received 

New-AzResourceGroupDeployment: Cannot bind parameter 'adminPassword'. Cannot convert the "Antwaynio97101#" value of type "System.String" to type "System.Security.SecureString".

Can anyone assist?
