create_vault.ps1

$password="super secret value"
$VaultName="SomeName"
 $KeyName="KeyToStorePassword"
 $ResourceGrpName="MyExistingResourceGroupName"
 $loc="chose a valid value"
 
 New-AzureRmKeyVault -VaultName $VaultName -ResourceGroupName $ResourceGrpName -Location $loc # (This creates a vault)
 
 $PasswordAsSecureString = ConvertTo-SecureString -String $password -AsPlainText -Force
 Set-AzureKeyVaultSecret -VaultName $VaultName -Name $KeyName -SecretValue $PasswordAsSecureString


# Retrieve vault key and create a Credential object.
$UserName="mysuer"
$PasswordForCredentials = Get-AzureKeyVaultSecret -VaultName $VaultName -Name $KeyName
$PasswordAsSecureString = ConvertTo-SecureString -String $PasswordForCredentials.SecretValueText -AsPlainText -Force
$Credential = New-Object -TypeName "System.Management.Automation.PSCredential" -ArgumentList $UserName, $PasswordAsSecureString

# This credential object can be used to create a VM (for example)
# An advantage is: you can fully automate VM Creation without storing password in version control.
