10 Habits to Stay Safe Online

We are living in a world with about 5.5 billion internet users, according to Forbes. Each person has an average of 8 to 12 active accounts, ranging from banking to entertainment and more. As the number of accounts and internet users continues to rise, it has become essential to maintain a secure online presence.
In this blog, I will dive into the 10 best habits to stay safe online.

1) Use strong, unique passwords

Why it matters: Stolen or guessed passwords are still the #1 way accounts get compromised. Reusing the same password across sites creates a domino effect.

What to do

• Use 12–16+ characters (passphrases are great: Correct-Horse-Staple-Cloud!).
• Include a mix of words + numbers + symbols (but readability > randomness you can’t type).
• Use a password manager to generate/store a different password for every site.
• Change passwords immediately after a breach notification (from the site or your password manager).

Pro tips

• Favor passphrases over short complex strings.
• Secure the password manager with a long master passphrase and 2FA.

Common mistakes

• Reusing passwords across banking, email, and social media.
• Storing passwords in browsers or notes without a lock.
• Relying on “security questions” with true answers—use fake answers you remember (and store them in your manager).

2) Turn on two-factor authentication (2FA/MFA)

Why it matters: 2FA blocks most account takeovers, even if your password leaks.

What to do

• Prefer app-based codes (TOTP) or hardware security keys over SMS.
• Turn on 2FA for email first (it’s the key to your other accounts), then banking, cloud storage, and socials.
• Save backup codes in your password manager.

Common mistakes

• Using only SMS when safer options exist (still better than nothing).
• Ignoring 2FA prompts due to “MFA fatigue.” If you get unexpected prompts, deny and change your password.

3) Spot (and stop) phishing

Why it matters: Phishing fuels ransomware, wire fraud, and identity theft.

What to do (the 10-second check)

• Sender: Does the domain match the brand? (support@paypaI.com with a capital “I” is fake.)
• Link: Hover to preview; the domain should match the real site.
• Tone: Urgency, threats (“account closed”), or prizes = red flag.
• Attachments: Unexpected invoices/ZIPs/PDFs—treat as hostile.
• Second channel: If unsure, verify via the official app/website or call using a number you find yourself.

Variants to know

• QRishing: Malicious QR codes.
• Vishing/Smishing: Phone/SMS phishing.
• Look-alike domains: micr0soft.com (zero, not “o”).

Common mistakes

• Clicking “Login” from email links instead of typing the known URL.
• Replying to verify requests with personal data.

4) Keep everything updated (patch early)

Why it matters: Updates patch known vulnerabilities used by attackers and malware.

What to do

• Turn on automatic updates for OS, browsers, and apps.
• Reboot weekly so updates finish installing.
• Update routers, smart devices, and plugins (set reminders if they don’t auto-update).

Common mistakes

• Postponing updates for weeks.
• Updating the OS but ignoring browsers, extensions, and drivers.
• Never updating router firmware (a common weak link).

5) Use secure Wi-Fi (and a VPN on public networks)

Why it matters: Unsecured networks allow snooping and session hijacking.

At home

• Set Wi-Fi security to WPA2-AES or WPA3.
• Change the default router admin password and SSID (don’t use your address/name).
• Disable WPS, enable auto-updates if available.
• Create a guest network for visitors and IoT devices.

On the go

• Assume public Wi-Fi is untrusted; use a VPN when you must use it.
• Prefer your mobile hotspot for sensitive work.
• Avoid logging into banking or email portals on café/airport Wi-Fi without a VPN.

Common mistakes

• Using open Wi-Fi without a VPN.
• Keeping factory router credentials.
• Mixing IoT gadgets with your work/personal devices on one network.

6) Click carefully (links, pop-ups, downloads)

Why it matters: Malicious links and attachments deliver malware and steal credentials.

What to do

• Hover before you click; check the actual domain.
• Download software only from official sites/app stores.
• Be cautious with browser extensions (install minimally; review permissions).
• If a page asks you to install a “codec/update,” don’t—go to the vendor site yourself.

Common mistakes

• Clicking “Enable Content/Macros” in unexpected Office docs.
• Installing cracked software (often bundled with malware).
• Trusting pop-ups that claim your device is infected.

7) Back up your data (and test restores)

Why it matters: Ransomware, theft, or hardware failure can wipe everything.

What to do

• Follow the 3-2-1 rule: 3 copies of your data, on 2 different media, 1 off-site.
• Use built-in tools:
  • Windows: File History or Backup & Restore.
  • macOS: Time Machine.
  • iOS/Android: iCloud/Google backups.
• Turn on versioning if available (lets you roll back before ransomware encrypts files).
• Test a restore quarterly to ensure backups actually work.

Common mistakes

• Keeping the only backup plugged in (ransomware can encrypt it).
• Never verifying that backups restore cleanly.
• Backing up only documents and forgetting photos, emails, and app data.

8) Protect your mobile devices

Why it matters: Phones hold email, MFA apps, banking, and location data.

What to do

• Use a strong screen lock (PIN/passcode) and biometrics.
• Turn on Find My Device and remote wipe.
• Update OS and apps; remove apps you don’t use.
• Review permissions (location, camera, mic); disable sideloading/unknown sources.
• Use app-based 2FA (and secure it with a device lock).

Common mistakes

• No screen lock or a 4-digit PIN like 1234/0000.
• Installing apps from random websites/APKs.
• Backups off—then losing the phone and the data.

9) Limit what you share online

Why it matters: Attackers use public info for targeted scams and password resets.

What to do

• Set social profiles to private where possible.
• Avoid posting real birthdate, address, school schedules, live location.
• Use different emails for public sign-ups vs. banking.
• Use non-obvious answers to recovery questions (store them in your manager).

Common mistakes

• Sharing photos that reveal addresses, travel dates, or badge details.
• Using the same public email for everything (increases spam and attack surface).

10) Stay informed (but avoid fatigue)

Why it matters: Threats evolve; light, continuous learning keeps you ahead.

What to do

• Follow a few reputable sources (official cybersecurity agencies, major vendors’ blogs, university CERTs).
• Subscribe to a weekly recap rather than real-time feeds if you get overwhelmed.
• Enable breach alerts in your password manager and change passwords promptly.

Common mistakes

• Doomscrolling every incident (burnout) or ignoring all news (out of date).
• Acting on unverified “breaking” posts—stick to credible sources.
