Hi priya,

generally we wont get any navigation or top bar for default login screen.

If you use custom page for login, then please look into the Selected layout of that page.

Solution is to create a seperate empty layout for login screen and use for that page.

Create a separate layout or slice layout for the login screen that does not include the navigation bar. When designing your layout, make sure that the username and password input fields, as well as the login button, are the central elements of the screen. Use styling and layout of elements so that the screen looks minimalistic and does not contain unnecessary interface elements.
