Displaying User Details in top right corner

[Jupyter123]

I have a created a login page which contains username, password and a sign in button.

So whenever the user signs in, he will be navigated to next page , only if the username and password matches the data in sharepoint list.

So, once the user is in next page, i should display the username in top right corner. Like Welcome User XXX!

So, how do i do that?

If you take it as USER().Display Name//User().FullName it will help
