I have added the password font as an attachment.

Maybe it is useful for other people.
password.ttf

Hello Sergey,

I have tried the password project, but it works not as I expected.
But I have found an easier solution. Now I have used a password font, what visualize each charcters as a bullet.

Maybe it's an idea to implement a password property to the editbox item in a next version of iRidium?
