So you probably know how to use 2 accoutns at once. Be in incognito mode AND regular mode. Well, on some mobile devices, there is a desktop site button. If you press that, it shows the desktop site. You can still use everything, but its slightly zoomed out. And you arent logged in...... SO MAKE A NEW ACCOUNT!! If you do this in both incognito and regular, you can be on 4 accounts simultaneously!

It saved my login data.
