Total Defense Security Tip of the Day

How to secure your voice assistant and protect your privacy
Our homes are getting smarter every day. We can turn on the lights with a voice command, check the weather from across the room, and play our favorite songs without lifting a finger. Voice assistants like Alexa and Google Assistant have made our lives incredibly convenient, but with that convenience comes a new set of privacy and security concerns. After all, these devices are always listening for their wake word. So, how do you make sure your voice assistant is a helpful servant and not a digital spy?
Step 1: Secure the Foundation—Your Wi-Fi
Your voice assistant is only as secure as the network it's connected to. Start by making sure your home Wi-Fi is a fortress. Use a strong, unique password for your router (not the default one that came in the box!) and use WPA3 encryption if your router supports it. Also, consider setting up a separate guest network for your smart devices, which isolates them from your main network and keeps your computers and phones safer.
Step 2: Mind Your Microphones
The microphone is the core of your voice assistant, so you need to be in control of it. Most voice assistants have a physical mute button. When you’re having a private conversation, a sensitive phone call, or simply don't want the device listening, hit that mute button. It's the most surefire way to ensure your device isn't accidentally recording your conversations.
Step 3: Delete Your Recordings
Many voice assistants, by default, store a history of your voice commands to improve their service. This means there's a record of everything you’ve said to the device. You have the power to delete these recordings. Go into the settings of the voice assistant's app on your phone or on the manufacturer's website. You can often review and delete individual recordings, or even set a schedule for automatic deletion. This helps ensure that a digital footprint of your commands isn't left in the cloud.
Step 4: Control Your Privacy Settings
When you first set up your voice assistant, it's easy to just click "I agree" and move on. But you should take some time to review the privacy settings. You can often adjust things like:
- Data Collection: Limit what data the assistant can collect and share.
- Voice Match: This feature allows the assistant to recognize your voice and provide personalized results. While it's convenient, it's another data point being collected.
- Opting Out of Human Review: Some companies use human reviewers to listen to a small percentage of recordings to improve their AI. You can often opt out of this in the privacy settings.
Step 5: Secure the Account
The account linked to your voice assistant is your key to controlling the device. Treat it like your most important online account. Use a strong, unique password, and enable two-factor authentication (2FA) if it’s available. This adds an extra layer of security, making it much harder for a hacker to access your account and all the data associated with it.
Step 6: Be Smart About Skills and Integrations
Voice assistants can do amazing things by integrating with other services, but be careful what you connect. A "skill" or "action" might ask for access to sensitive information. Be selective about what you connect, and regularly review the third-party apps and services that are linked to your assistant.
The Bottom Line
Voice assistants offer a fantastic glimpse into the future of technology, but it’s up to you to manage the privacy implications. By taking these simple, proactive steps, you can enjoy all the convenience of your smart device while keeping your personal information safe and secure.
