Switch account

I have activated account in my computer but I am far from my computer and I have another computer I would like to sign in the new computer how can I do that ?

You should be able to use SketchUp on the new computer. If you are signed in with three computers you may see a message about too many activations. If you do see a message about that, read this article to see how to manage your devices:
