Hi,

Is there a way to convert a string to a secure string other than?

$password = Read-Host "Enter password" -AsSecureString

Cannot bind parameter 'ConnectionPassword'. Cannot convert value "string" to type "System.Security.SecureString"

There are two cmdlets you might find helpful - ConvertTo-SecureString and ConvertFrom-SecureString. If you are trying to get credentials (username and password), the Get-Credential cmdlet might work for you. (Its password property is a secure string.)

Oh, if you use the Get-Credential and you need to get the unencrypted password, you can access it like this:
$credential = Get-Credential
$credential.GetNetworkCredential().Password
