Question about using a friends computer

Hello Guys,

So, it's been awhile since I've posted anything and thats bc my cat decided it was a good idea to dump a cup of water onto my laptop. My laptop is still broken so i decided to use a friends computer to access my account. Is this allowed or do i have to purchase a new computer first? And when i do purchase a new computer, will my friend be able to make an account if they wanted to?

Thanks

I didn't find the right solution from the internet.
