Pattern: Use of Username/Password parameter

Issue: -

Description

Either set the type of the Password parameter to SecureString or replace the Username and Password parameters with a Credential parameter of type PSCredential. If using a Credential parameter in PowerShell 4.0 or earlier, please define a credential transformation attribute after the PSCredential type attribute.

How

Change the parameter to type PSCredential.

Example of incorrect code:

function Test-Script
{
    [CmdletBinding()]
    Param
    (
        [String]
        $Username,
        [SecureString]
        $Password
    )
    ...
}

Example of correct code:

function Test-Script
{
    [CmdletBinding()]
    Param
    (
        [PSCredential]
        $Credential
    )
    ...
}
