A few years ago I got into improving my knowledgebase of personal security - theory and tools - but it didn't go much farther than reinforcing everything with 2FA and setting up a password manager, plus setting up a VPN and full disk encryption.
It seems like we're amidst a rising tide of data breaches due to, IMHO, laziness and cheapness on the part of many companies storing personal data.
So, recently I've embarked on my second journey to improve my own security via habits and software and teaching myself. Privacytools has been a super helpful resource. My main lesson this time is to take ownership/responsibility for my own data. To that end, I have switched to KeyPass with yubikey 2FA (still trying to figure out how to get 2FA with yubi on my android without NFC), moved over to Joplin for my note taking (away from Google and Evernote) and also switched to NextCloud for all of my data storage and synchronization. I'm also de-Googling myself, current due-date is end of March when Inbox is shut down.
So my question / discussion topic here, is, what are everyone's thoughts on the future of practical personal security and privacy? More decentralization and self-hosting? That's what it looks like to me. Blockchain tech would be cool for public objects like news articles, images etc. but from what I understand that has zero implication for anything personal. The other newish tech is PGP signatures, which I'm still having trouble implementing/finding use for, but surely that will change.
There is this topic but that ended up just being about encryption which I think is a no-brainer at this point. I'm more so looking for the leading edge trends.
