- Ditch Chromium.
- Use a Password Manager instead of "log in with Google/Facebook/whatever"
- Keep tabs on Mobile App permissions and revoke as many as you possibly can. I revoke location permissions from every single app except Navigation apps, which have to ask for location permissions. If possible, remove apps in favor of Native Alpha / Hermit web apps
For me the real value is that a good password manager makes it easier to not use "login with Google" for everything
