How can I start a second user in the same browser (via a tab) who of course has a different password.
For example, 2 teams play in the same room and want to enter results on the same computer from 2 different users.
thx

It depends on how cookies are handled in different tabs in the browser. For example, in Google Chrome the cookies are shared among tabs so you cannot have different sessions in different tabs.
