                                </Style.Triggers>
                            </Style>
                        </TextBlock.Style>

There is the PhoneTextBox in the official Windows Phone Toolkit, covered here.

Sample code:

<toolkit:PhoneTextBox Hint="Password"/>

To add toolkit to your project : Type the following into your package manager console :
PM> Install-Package WPtoolkit
And

xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"

inside <phone:PhoneApplicationPage tag in the xaml page
