My little brother was giving his Netflix login to half his school. Tried to explain account security risks like credential stuffing. He shrugged it off, said it was no big deal. So I changed the password on him as a wake-up call. Cue the frantic texts from his friends asking why they got logged out. He was furious, but I walked him through setting up individual profiles. Now he gets why shared passwords are a bad idea. Whole thing felt like a mini cybersecurity intervention in our living room.
