Those are dojo widget. Mendix migrated to the React. So you cannot use them anymore. 

Hello Suraj,

In Mendix 11.4, the Login ID Text Box and Password Text Box are not fully removed.

But they are old Dojo widgets and they do not work in the React client. If you use the React client, they will not show in the Toolbox. (Dojo client deprecated and will be removed in Mx12)

Login ID Text Box | Mendix Documentation

Password Text Box | Mendix Documentation

Sign-In Button | Mendix Documentation

Mendix recommends using the normal Text Box (set password mode for the password) and a Button like in the Atlas login page template.

Notes from Mendix Docs:

"The sign-in button/login ID text box/password text box widget is a Dojo widget.

This widget is not supported on native mobile pages.

This widget is not supported in the React client.

Upgrade it to the normal input and action widgets as shown in the Atlas login page template. See the Mendix React Client's Migration Guide for more information.

If you switch to the React client, the widget will not appear in the Toolbox.

The Dojo client is deprecated and will be removed in Mendix 12. It continues receiving security and stability updates until the end of support of Mendix 11.24."

the ID, password, submit button, are all usable without dataviews.

does this mean we need to remodel how loggin in works?

edit:

It looks like thsi is how atlas does this.
