It keeps prompt me to enter password

Here is my code but it keeps asking me for password instead of inserting the password 

 $Users = Import-Csv -Path "c:\csv\test.csv"
$UserPassword = ConvertTo-SecureString "Pa$$w0rd!" -AsPlainText -Force

ForEach ($User in $Users) {
    New-localuser -name $User.name -Description "user"
    Set-LocalUser -name $User.name -Password $UserPassword -Description "Password"
    Add-LocalGroupMember -Group "Users" -Member $User.name
    Add-LocalGroupMember -Group "vpn" -Member $User.name
}
