None of the links are exactly what I was looking for, however I have found a solution based on the plugin you posted. I have tried force login before, but users were redirected to their profile in the backend after logging in, which is what I want to avoid.
When I change the role of an existing user to “no role for this site” though, they seem to be redirected to the actual website instead of the backend when they log in, which is what I wanted. So problem solved, thank you for your help bdbrown ??
