# Device Security Guide

Protect phones, laptops, and tablets with updates, strong account security, cautious public Wi-Fi habits, and a VPN when you need encrypted traffic.

## Why device security matters

A VPN helps on the network path, but device hygiene still decides whether malware or weak accounts can undo that protection.

## Steps

1. **Keep devices updated** — Install OS and app updates so known vulnerabilities are patched.
2. **Harden accounts** — Use unique passwords and enable two-factor authentication on important accounts.
3. **Encrypt untrusted networks** — Use AstraGuardVPN on public Wi-Fi and other untrusted networks.
4. **Review permissions** — Limit app permissions and remove software you no longer use.
