There are several ways to change your current group:

1. On a mobile phone or tablet, you can swipe right and the list of groups will appear.  Simply click on the group name and you will automatically switch your current group.
2. You can also on all devices click on the group icon in the top left hand corner and this will also reveal all the group names. On the desktop app, the group names are visible most of the time, until the page becomes too small.
3. You can also click on the groups tab, view the list of groups and click on the name to switch immediately to that group.

On the desktop and browser apps, the groups are visible on the left hand menu bar at all times. Simply clicking on the group icon will switch you to view the logins within that group.
