Total Defense Security Tip of the Day

Is someone else watching your Netflix? How to check for unknown devices
When you settle down for a weekend binge, you expect to see your profile—not random activity from a device you don't recognize. While it might just be a friend sharing a password (bad habit, by the way!), an unrecognized device on your streaming account could be a red flag pointing to a much larger cybersecurity problem.
It’s time to take a quick, proactive step to protect your digital life, starting with your favorite streaming service.
The Hidden Threat of Shared Logins
Subscription services like Netflix, Hulu, Spotify, and others are prime targets for hackers. Why? Because most people reuse the same email and password combination for everything, including their bank and work accounts. If a hacker cracks your weak password or steals your credentials from a data breach at a different site, the first thing they do is test that combination on popular services like Netflix.
If they get in, they gain two things: free entertainment (annoying!) and confirmation that your password works—making your other, more important accounts vulnerable (terrifying!).
Action Steps: How to Check Your Netflix Activity
Stopping unauthorized access is simple. Netflix makes it easy to see exactly where your account has been active. You should get into the habit of checking this page at least once a quarter.
Here is the step-by-step process:
- Open Your Account Page: Log into Netflix on a web browser (not the app) and navigate to your Account settings.
- Find the Settings Section: Scroll down until you see the Settings or Security & Privacy area.
- Click “Recent device streaming activity”: This link is the key. It opens a detailed list showing the location (city/country), IP address, and type of device (e.g., iPhone, Smart TV, Chrome Browser) that recently accessed your account.
- Review and Look for the "Odd One Out": Carefully scan the list. Do you see a login from a city you've never visited? A device model you don't own? Anything that seems out of place is a potential intruder.
Someone’s There. Now What?
If you spot something suspicious, don't panic. You have two crucial immediate actions to take:
- Log Out All Devices: In your Account settings, look for the option to “Sign out of all devices.” This immediately boots everyone—including yourself and any legitimate users—off the account. This is the fastest way to stop the unauthorized access.
- Change Your Password Immediately: This is non-negotiable. Choose a strong, unique password that you have never used anywhere else. Make it long, use a mix of uppercase, lowercase, numbers, and symbols. Using a password manager helps immensely here.
By checking your streaming device activity, you're doing more than just protecting your watch history; you're using it as an early warning system to protect your entire digital life. Make it a routine and keep your accounts secure!
