You do not need to be a security expert to stay safer online. A few consistent habits can stop most common account takeovers and scams before they start.
Use a password manager, turn on multi-factor authentication everywhere it is offered, and treat unexpected links and urgent payment requests with skepticism. Keep phones and laptops updated, and separate personal and work accounts when possible.
Small routines beat complicated tools. Review app permissions once in a while, and back up important files so a lost device or ransomware scare does not wipe out years of work.
