Online Security FAQ
Straightforward answers to common online security and privacy questions.
How do I know if my home Wi-Fi is secure?
The first step is always changing your router’s default password, since those are easy for attackers to guess. Make sure your network uses WPA3 or WPA2 encryption, turn off remote management, and keep your router updated with the latest firmware to stay protected.
How can I tell if an email is a scam?
Look for strange sender addresses, spelling mistakes, and unexpected attachments. Scam emails often try to create a sense of urgency to get you to click something quickly. For a simple walkthrough, see my guide How to Spot Scam Emails.
Do photos really reveal my location?
Yes. Most phones add hidden GPS data to every photo, which can show where and when it was taken. You can remove this information easily by following my guide: Stop Oversharing: Remove Hidden Data from Photos.
Should I use a VPN at home?
Yes. A VPN keeps your internet activity private from apps, websites, and your internet provider. It is also very useful when you use public Wi-Fi. If you want a beginner overview, check out VPN 101: Keeping Your Business Your Business.
What’s the easiest way to protect all my accounts?
Use a password manager and enable two-factor authentication (2FA). These two steps alone prevent most account compromises.
Do smart home devices collect more data than I think?
Many devices collect more information than people expect, including voice data, usage habits, or location details. Adjusting permissions, turning off features you do not need, and keeping devices updated helps limit what they collect. For more details, see Smart Devices: The Biggest Gossips in the House.
