Answer 1

Building on Briantist & Graham: This will ask for a credential and store it on first run, then reuse it on subsequent runs from the same code. In my case drive H is the user's home directory, used for tidiness, not security.

# the path to stored credential
$credPath = "H:\Secrets\Cred_${env:USERNAME}_${env:COMPUTERNAME}.xml"
# check for stored credential
if ( Test-Path $credPath ) {
    #crendetial is stored, load it 
    $cred = Import-CliXml -Path $credPath
} else {
    # no stored credential: create store, get credential and save it
    $parent = split-path $credpath -parent
    if ( -not ( test-Path $parent ) ) {
        New-Item -ItemType Directory -Force -Path $parent
    }
    $cred = get-credential
    $cred | Export-CliXml -Path $credPath
}

This block of code can be chucked in any script that needs it and the problem is more-or-less solved from then on.

Could possibly also check for a successful credential before writing it if the application permits it. Note that if the password changes the user must delete the file. [edit: missing parenthesis in code]
