Set the text field’s
When a user enters a password into a field, you generally do not want observers to be able to read the password. This is a basic security precaution. The common convention is to display only asterisks in the field as the user types. This way, the user can see that he is successfully entering a value without observers being able to easily read the password.
To create an input field that is automatically masked with asterisks,
you only need to set the
myTextField.password = true;
When you set the password property to

myTextField.password = true; myTextField.text = "some text"; // Text field displays: *********
Recipe 8.5. Password text fields only obscure the display of the text; the value contained by the text property is unaltered. Therefore, when you send the password value across an Internet connection, it is not encrypted. If you need additional security when sending the password, you should use HTTPS or use an encryption technique such as a cryptographic hash algorithm, as Branden Hall discusses at http://www.macromedia.com/desdev/mx/flash/extreme/extreme003.html.
