Bluetooth connectivity can expose you to numerous security risks if you’ve not taken steps to prevent unauthorized access to your devices.

Keep reading for detailed info that you need to enhance the security of your Bluetooth speakers and how to prevent unauthorized access to Bluetooth speakers. 

There are simple steps you can take to prevent unauthorized access to Bluetooth speakers including using a security code, turning Bluetooth off when not in use, setting Bluetooth to undiscoverable, pairing in private, using an audio jack, or installing security updates. 

Bluetooth speakers are quite useful – the size, quality of sound, and wireless connectivity make these speakers portable, convenient to use, and efficient.

So, security concerns can often limit your experience. Here are reliable ways to prevent unauthorized access to Bluetooth speakers:

1. Use A Security Code

Modern Bluetooth speakers have advanced security features, including security codes that limit Bluetooth pairing.

For anyone to be able to access your speaker, they must have your code. If you keep the code secured, you can prevent unauthorized access without spending any money.

If your device uses a security code and others have access to it, in some cases the security pin can be changed, check the manual. However, most Bluetooth speakers I’ve seen use a default code like “0000” or “1234”, and don’t allow it to be changed.

2. Turn Off Bluetooth 

Please remember that keeping Bluetooth active allows hackers and criminals to discover other devices you paired it with before. If they successfully spoof the devices, they can find your login details and access your speaker. 

Turning Bluetooth off when you are not using the speaker can solve this security issue. If someone gets unauthorized access to your speaker, turning Bluetooth off is an easy way to kick someone off your Bluetooth speaker.  However, some hackers can access your Bluetooth speakers even when it is not connected to another device.

Others can also access a speaker that has been turned off (not active). So, after turning it off, you need to set the speaker to undiscoverable. 

In fact, for initial pairing, some Bluetooth speakers require a physical button to be pressed to switch to discovery mode. In this case, the speaker will not allow just anyone to pair with it without physical access which is great for security. 

3. Set Your Bluetooth Speaker to Undiscoverable

This is another great way to kick someone off your Bluetooth speaker. Some Bluetooth speakers automatically enter pairing mode and become discoverable by other devices when turned on, and have no discrete Bluetooth button.

Set Your Bluetooth Speaker to Undiscoverable

This will increase the time you require for pairing with other devices. Nonetheless, it is effective at protecting your Bluetooth speaker from strangers with ill motives.

Other Bluetooth speakers allow you to toggle their visibility in the settings. Check the Bluetooth settings, and make sure the Bluetooth of your device is invisible. This ensures that nobody sees your device’s Bluetooth to connect to it even though the device is on.

In addition, whenever there are notifications of new devices trying to connect with your speaker, make sure you decline the request.

4. Unpair Bluetooth Speakers from Others People’s Devices

This is a quick way to kick someone off your Bluetooth speaker without turning it off. Once you pair your speaker with a device, you give hackers access to some of your private data.

For example, if you connect your speaker to a rental car, its data may be shared with the vehicle.

To be safe, you should unpair the speaker and clear any personal data before returning the car. If you are selling a car that has Bluetooth, you should follow the same procedure.

5. Keep Bluetooth Off When Not In Use

When your speakers are not in use, turn them off. It is that simple, common sense, yet many people keep Bluetooth on, exposed to hackers. 

Remember, once someone pairs with your device, that can last for days. many Bluetooth speakers will store a Bluetooth profile indefinitely.

You can either try to erase the Bluetooth profiles or if you are using a small portable Bluetooth speaker, just bring it with you on the road and when it is out of range of the hacker’s device, delete the profiles. 

6. Pair in Private

Your Bluetooth speaker is most vulnerable when it is in pairing mode. This is the moment it is actively searching for other compatible devices. Eavesdroppers understand the risk and can gain access at these moments. 

The perfect remedy is to avoid pairing your Bluetooth speaker in crowded places such as train stations and coffee shops.

Besides moving away from public settings, you should keep track of all your connections and reject all unknown pairing requests.

7. Install Software Updates

Bluetooth speaker’s security issues sometimes originate from loopholes in the application. The manufacturers continuously evaluate the security of their products and release advanced versions to mitigate potential risks. 

Continuously check for updates to your Bluetooth app and be sure to install it as soon as possible. This way, your app may have advanced features that protect your speaker. 

You can achieve more if you can pair your speaker with secure devices using a secure application and a more secure Bluetooth connection. 

8. Use an Audio Jack

This is a simple option that is worth a try. It doesn’t involve a lot of work. Many Bluetooth speakers are designed to prioritize wired connection over wireless.

They will not allow any device to pair with them when they are connected with an audio jack through AUX. There are many Bluetooth speakers that use AUX or audio jack connections. 

Use an Audio Jack to prevent unauthorized access to bluetooth speaker

You can find an old headphone that you no longer use and cut the audio jack. You can even use a microphone splitter as well. Stick into the speaker, and that should be enough to stop wireless connectivity. 

Before you try this method, test it with a friend to ensure your Bluetooth speaker prioritizes wired connectivity.
