General question on tracking single registered users

Hi,
I have a few questions on tracking users within a login area. I use the latest self hosted version of Matomo.
Users to be tracked will log in and get a uniqe user ID. I want to view all users grouped, plus single user’s actions. Is this possible?
Do I need to buy/install/activate a special module for this, or it it covered by standard features?
Thanks

Hi,

I think you want to take a look at the User ID feature:

Just keep in mind that you should follow your local privacy laws when doing so.
