In tmux I only have 2 groups, as opposed to the expected 5:
$ groups username sudo staff website1 website2 $ tmux $ groups username sudo Why is this and how do I fix it?

To create multiple windows, you need at least one tmux session running. You can simply type CTRL + b, let go of both keys and type 'c'. This will open up a new terminal. At the bottom, you can see that there are now multiple windows (0, 1, 2) in the session.
ctrl + b + " to make a Horizontal split. ctrl + b + left arrow to move to the left pane. ctrl + b + " to make a Horizontal split.
To enter command mode, type prefix>: followed by list-sessions or ls to view a list of currently active Tmux sessions. By default, list-sessions are bound to the prefix> s key combination. With j and k, you may explore the session list and activate one by hitting enter.
Sharing between two different accounts with tmuxFor different users, you have to set the permissions on the tmux socket so that both users can read and write it. There is only one prerequiste, that there be a group in common between the two users. If such a group does not exist it will be necessary to create one.
tmux allows you to create "session groups" - multiple sessions that can all attach to the same set of windows. In the left terminal, create a new session+window group.
Each terminal is a separate session. This is a problem if you use the tmux attach command as your login shell because then all your Terminal.app windows now synchronizes to the same view and you lose the benefit of having a separate window.
So the correct way to structure commands in Tmux is: That is, we have to press the keys CTRL+B and then the command. For example, to create a new session, the command would be C. So, to create a new session we need to press CTRL+B and next C – CTRL+B, C. Another fantastic feature of Tmux is that we can “save” a specific session.
With tmux, you can create multiple terminal sessions that can be opened (attached) and closed (detached) or displayed simultaneously all from one window. Multiple panes using tmux Learning how to use a terminal multiplexer will save you a lot of headaches if you spend a lot of time in the terminal.
Perhaps your tmux server was started before you were added to the additional groups. The server process and any processes which it starts will only have the permissions that were in place when the server was started.
You can fix this by closing all sessions and starting a new server. Once you've quit any programs that you care about which are running inside tmux sessions you can use tmux kill-server to ensure that the old server process is ended. Then when you run tmux again it will automatically start a new server which should have all of your current permissions.
