How long is the usual wait for a root password reset on a droplet?

Hello, so I’ve had some problems in the last hour. Completely new to both setting up a website and ubuntu and wordpress and was having great success with wordpress installed, a theme up and running, until…

I updated wordpress and then logged out, tried to log in again and my site disappeared. I couldn’t access the log in or the website at all. I hadn’t set up an ftp service until I found out now… realised I couldn’t set one up due to not adding a new user on the console. So I tried to access the console, it was asking for a username and password, I assumed it was the same as the SSH key I set up with the droplet but these details were not accepted. So in frustration and definite beginner action, removed the SSH key and clicked reset root password.

It has been processing this action for over 20 minutes now. Is this usual or have I done something terrible?

Also, how do you remove a droplet and add a new one if it comes to that?
