Assuming they log onto this PC with the same credentials but need to log onto Qlik Sense
with their own credentials... Otherwise if they log onto the same pc with different credentials it should
just work.
Which Browser are you using and version?
Under IE, Security Settings (Custom) there is the option under User Authentication - Logon
Select "Prompt for user name and password"
Not sure about the other browsers but I am sure they will have something similar
