I have always been curious about this. Did you get them to use other services or did they stubbornly refuse and you just accepted it? I am talking using Chrome, using Windows, using social media like Tiktok or Facebook or Instagram, etc. Bonus points if you have kids because that is even more work in the privacy realm
I got my SO to use a password manager.
She got sick of pihole and my firewall blocking her Facebook memes, so she has her own segregated WiFi network, then she’s less of an attack vector for me.
Aslong as she uses 2fa on her main accounts and has a password manager I’m happier than most.
