Another User Extension contribution - PasswordField (see screen shot attached). Credit goes to http://extjs.com/forum/showthread.php?t=20417 for providing the concept and idea - though not much was shared other than the images.
Add the PasswordField.jar to your lib and the following line to your gwt.xml
The code snip below shows how to use it within a normal FormPanel or FormLayout.
final PasswordField pw1PwdFld = new PasswordField();
pw1PwdFld.setEmptyText("Enter a strong password");
