my friend wants to do work on my computer, but wants to log onto her jotform account, how does she do it?

There are different options.

1. Your friend can use another browser on your computer and log in to JotForm from that browser. If they don't have an account, they can Sign Up from this page. https://www.jotform.com/signup/

2. It is also possible to use the same browser but open it in Private Mode (Incognito).

3. You can always log out from your account, then your friend can log in to her account and when finished, you can log in to your account again.
