Dynamic Page URL

Hello,
I am creating a dynamic members only page area. How do I get the URL to show like this:
for example :https://www.mycompanyname.com/username ← this would be the members name or business name.

Is this possible?

like this…

I am sorry I should have been more clear on what I am asking. Can I remove the dataset from the URL and just add my website / the username. Without it messing with the dataset on the page?
right now its mywebsite/members/ID
Aslo could I have private member only page without using the ID field?

@emsimmons77 the link i posted does not require or say anything about a dataset

@mikemoynihan99 I appreicate the information. Thanks
