The registration and login form displayed is not the same as the demo

I have been using WP v5.6, imported organic 2 demo ( https://xstore.8theme.com/demos/2/organic02/ ) and config it. But in my website, login form and registration form displayed different from demo website:
– In my website, when click My Account icon in top right, i was redirected to login/registration page. But demo website show right drawer navigation.
– In my website, registration form only show email input ( after register, my password will be sent to my email). But demo website show password/ confirm password input/login by Facebook.
How can i fix my website to same demo website?
In addition, how can i add “Login by google” feature? change logo in page footer?

Thanks so much.
