I use iOS with an old Apple Account which is connected to a proton mail adress (changed from gmail)
I would delete the whole account and send a data deletion request. After that I would create a new one.
I use 2FA app (Ente Auth) and a password manager (Bitwarden) and use password with over 30 characters.
Try to buy two FIDO2 Keys and use Passkeys as well as MFA with FIDO2.
My recommendation: USB-A YubiKey 5 NFC Two Factor Security Key | Yubico
Besides Reddit and Goodreads where I use aliases and fake names, I have no other social media. I deleted Facebook and Instagram where I didn’t post anything anyway.
Is there a reason for that? Especially reddit is pretty hostile.
I have a Windows laptop with a local account and I disabled as much of the telemetry as possible and deleted One Drive and Copilot from the PC.
Get away from Windows and switch to Linux.
For browsing the web I use Brave, Mullvad, Firefox and Librewolf for different purposes and I use DuckDuckGo and Ecosia as a search engine. All browsers are set up to delete search and browsing history upon closing and I have shields on in Brave.
LibreWolf can’t auto-update itself on Windows, so please check for updates every time you boot up your device.
I use private DNS system wide on my PC and on my phone, I don’t use a VPN.
Maybe something over TLS like DoH(DNS over HTTPS) with blocking? NextDNS as an example.
I don’t know really. I’m kind of scared of everything turning into a giant police state in the EU the most.
This will not happen so fast.
