Illustration of safer everyday device habits

In plain words

This guide keeps the security basics simple. You do not need technical knowledge to use these habits.

Core idea

Good device hygiene lowers the blast radius of mistakes. The goal is resilience, not perfection.

Why this matters

Most account incidents happen through predictable behaviors, not advanced attacks. Good basics create margin for mistakes and reduce recovery pain.

Common mistakes

  • No screen lock or weak unlock PIN
  • No tested backups
  • Installing apps from unofficial stores

Practical checklist

  • Use strong device unlock settings and auto-lock timers.
  • Keep encrypted backups and test restore occasionally.
  • Review app permissions quarterly.
  • Remove software you no longer need.
