I have a different password for each service I use. Each password is 30+ characters long and completely random with letters, numbers and special characters. There’s no way I could remember any of them and they’d be a hell to type out manually. I use KeePass on every device I own and it’s synced over my NAS. So it’s super convenient and no risk for leaks.
My PC has a i7-4790k overclocked to 4.5 GHz. It runs smoothly since I got it when it came out and it is still not a bottleneck in any of the games I play. But if I wanted to upgrade to Windows 11 I would need to buy a new CPU, new main board and new RAM, and it would not improve my gaming experience at all. It was my last machine running windows which I changed to Linux 2 months ago and I haven’t looked back.
