Add register login at top right corner

Hello,

I am using the HitMag WordPress theme. On the website, register & login is showing on the sidebar (widgets). But I want to show register & login at the top right corner in button form. I want to display like this https://i.imgur.com/1COhH97.png

Could anyone let me know how to display buttons?
