Various stuff, some not best practice per se but here it is (more focused on digital sovereignity than anything else these days):

• Degoogled my android phone to the greatest degree without breaking essential stuff. Noticed better battery life so a unintended win
• moved off from Outlook to paid hosted email in my country. Cheap, reliable and have full control over it. Also in case of any issues way easier to get support
• Cancelled M365 subscription as I don’t use office and was using it purely for cheap OneDrive backup for family
• Moved all my files for me and my family off of OneDrive to my Synology NAS. Ended up using more of its functionality, happy with the purchase. Doing the occasional backup to the external drive just in case
• Ditched proprietary authentication apps in favor of Keepassxc. TOTP codes on any synced device so if I lose my mobile phone I don’t get locked out of anything. Local only was mandatory
• For work stuff I use ente auth, separating work and private MFA
• Replaced windows on all my machines with linux. Its become more user friendly in recent years and does not get in my way.
• Replaced all US service providers with EU ones where possible, if any service gets cut off for EU I won’t lose access to anything important, never know with Trump these days…

KDE plasma. Coming from 30 years of running exclusively windows it’s just the most comfortable and easy for me to use (way more than Gnome). Easily configurable, works. Can’t ask for more.
