Once a user is logged in

I have done the freeCodeCamp MERN tutorial and several MERN - build Login/Auth tutorials. I want to now add a login feature to the freeCodeCamp exercise logger app .

Any suggestions as to how to manage what data is rendered once a specific user has logged in? Is it as simple as adding the user’s name value to any GET requests? Should I store the user’s name in a state variable and then input that variable into any GET url? Does this sound right?
