Hi Ramzy,
How to: Create a new page, add the login widget(s) to it and make it available for anonymous users
Where to start: Rapid developer learning path https://learn.mendix.com/link/path/10
Good luck, Rene
Dear Ramzy,
The "Login form widget" should be deprecated as Mendix now natively Authentication widgets
