I use a random pass generator.
Avoid all password managers at all costs. I put it down manually.
I am going be getting a subscription to a non Google email. Not sure which one yet. I think it's called fast mail.
Avoid everything Apple.
Avoid everything social media. I still use them for lurking but every single service has its own email and generated pass.
Avoid posting anything anywhere forever. (As little as I possibly can)
Getting my info and my associates info completely wiped from all data brokers and all links from all search engines purged.
Use a custom ROM and a rootable phone. I'm not a fan of how big Google is. I'm not a fan of how little support they offer for their services (let's be honest it doesn't exist). But at the same time Google really does make great software at the cost of zero actionable support. It works for now. There are open source alternatives in the works to replace the core of Google services I just haven't checked if I can use it as a daily driver just yet (without many bugs).
I use chrome with privacy badger extension by the EFF
Another extension which is called uMatrix (have been using it since Beta, HTTPS-Everywhere). It will break your internet experience if you don't know how to use it.
Simply put the only firewall you will ever need. Doesn't use many resources and is extremely straight forward.
I also use the signal app for communication. As much as I possibly can. (It took me a year or two but I've converted over 50+ people into using it)
Stating the obvious. But I haven't gotten a single virus from torrents since the Napster days. You'll get them from software most of the time anyways (crack generators, old software etc...).
