Can I use the default ubuntu user in EC2 to do git clone?

So I have spun up a simple ubuntu EC2 istance with lamp.
I installed everything with apt-get as root sudo su

Now I have to clone the repository of the website, i.e.:

git clone ...

inside a dir in /var/www/...

Can I do this as ubuntu, or should I create another user and do git clone with this user?
