Best practices, recommended tools and tips to protect your digital life every day.

Cybersecurity isn't just for experts. A few simple habits are enough to dramatically reduce the risks. Here are the essentials, organised into clear, actionable blocks.

checklist Best practices

key

Strong passwords

Use a unique password for every account
At least 14 characters with uppercase letters, numbers and symbols
Prefer a passphrase that's easy to remember (e.g. MyCat!Loves3Treats)
Never share your passwords by email or message

verified_user

Two-factor authentication (2FA)

Enable 2FA on every account that offers it
Prefer an authenticator app (Aegis, Authy) over SMS
Keep your backup codes in a safe place
SMS is still better than nothing — enable it if there's no other option

update

Updates

Install updates as soon as they're available
Turn on automatic updates for your OS and your apps
Updates fix critical security flaws
Outdated software is an open door for attackers

Safe browsing

Always check for the HTTPS padlock in the address bar
Don't click suspicious links in emails or texts
Use an ad blocker (uBlock Origin)
Be wary of public Wi-Fi — use a VPN if possible

backup

Backups

Apply the 3-2-1 rule: 3 copies, 2 media, 1 off-site
Back up your important files regularly
Test restoring your backups
An external hard drive or an encrypted cloud will do the job

Phishing & scams

Check the sender's email address, not just the displayed name

When in doubt, go directly to the official website (without clicking the link)
Official organisations never ask for your password

lightbulb Quick tips

Check for data breaches

Visit Have I Been Pwned to check whether your email address has been compromised in a data breach.

Turn off unused Bluetooth & Wi-Fi

When you don't need them, turn off Bluetooth and Wi-Fi. It reduces your attack surface and saves battery.

Use email aliases

Services like SimpleLogin or Apple/Proton aliases let you create disposable addresses for each sign-up.

Encrypt your hard drive

Enable BitLocker (Windows) or FileVault (Mac) to encrypt your disk. If it's stolen, your data stays inaccessible.

Audit your app permissions

Regularly review which apps have access to your camera, microphone, location and contacts. Revoke anything unnecessary.

Separate your activities

Use a different browser (or separate profiles) for personal and work use. It limits cross-tracking.
