How would you be able to differentiate between different people logging on from say the same household?

It depends on the system design, if already exists. Most systems including
social media platforms like Facebook, Snapchat, X use credentials and as long as
different people log in using different credentials, the problem is resolved
instantly. The problem will remain however when the system refers to IP address
or some sort that identify the users from the 'household'. If that's the case
and it is critical to identify, I would suggest the change in the log in method.
If that is hard to implement due to some technical reasons or the behaviors of
the users, we can consider different interactions between each user and the
system to distinguish. For example, if it is a social media account, there's a
possibility the preference on media would be different and/or the people they
interact with. What's also important is to consider why do we want to
differentiate the users. That will determine whether the trade-off of having the
revised system and not having the access to the data, which one is more
preferred.

Users logging in from the same household would probably use different accounts
that would help identify different users even if they are logging in from the
same location. In case the users are logging in from the same location using the
same account I would use the device to potentially differentiate the different
users although this may cause false positives when some users have multiple
devices.
As an example when using a netflix account at home, me, my wife and my two
daughters share the same account and location. However if we use only the phones
we can identify three different users watching very different content. It is
worth mentioning this is just an approximation.
