Do I have to sign out between sessions?
You don’t have to sign out of our server, but doing so will prevent anyone else who might use your computer from accessing the server in your name. We recommend that you sign out if you are using a public computer, such as one in a library. Signing out is not necessary if you participate in another Lab project and need to switch between projects.
You can sign out of the server by clicking the “Sign out” link found in the top right of the page.
