I smashed my head with this one for hours.

Fixed issues: The TextInputLayout password toggle is now disabled by default to avoid unnecessarily overwriting developer-specified end drawables. It may be manually enabled via the passwordToggleEnabled XML attribute.

So to have it back, you have to:

 <android.support.design.widget.TextInputLayout
    ...
    ...
    app:passwordToggleEnabled="true">

     <android.support.design.widget.TextInputEditText
          ....
          ....
          .... />

</android.support.design.widget.TextInputLayout>
