For me, the basics are using strong passwords, turning on two-factor authentication, and always checking for HTTPS before entering any sensitive info. It’s like locking the door and checking the peephole!
Strong passwords and 2FA are def a must. I also like to use a good password manager to keep things organized. And gotta have a solid firewall and anti-malware setup. Oh and don't forget to keep all your software patched and up to date - security bugs get found all the time!
