Callout Designer with Password

Hi Everyone.
I am learning how to use the Callout Activity and Callout Designer. I need it to get some Login Credentials, I saw on the UiGuide Callout Designer that there exist the possibility to use a Callout it for password, but I can’t find Password in the Basic components categories of the Deisgner. I looked the text Field properties, too, but nothing.
Any one can help me?
Thank you!
