How to Know if Your Android Phone Is Linked to Another Device

Your Android phone isn't just a standalone device; it's a hub that interacts with a whole bunch of other devices. So, when you take pictures and back them up to Google Photos, you can view them in an album on your TV using the Google Photos app. Or your Nest Smart Display may be tracking your sleep on your nightstand and sharing that information with Google Fit on your phone and your smartwatch.

The convenience of this interconnected ecosystem is clear. However, from a security perspective, it’s a liability if you lose track of a device that has access to your Google account. That's why it's critical to keep tabs on what may be connected so that the old tablet, phone, or Chromebook you sold or gave away won't come back to haunt you.

How to view and manage your connected devices

1. Navigate to your Google Account management

On any web browser

Go to myaccount.google.com.

2. View connected devices to see if any don't belong

Once you have accessed Google Account management, select ‘Security’ from the navigation bar. Then, scroll down to the ‘Your devices’ section. You’ll see a list of the devices where you’re logged into your Google account. Click on the ‘Manage all devices’ link to see more details.

On the ‘Your devices’ page, you’ll see your logins grouped by type of device. For example, I have Windows computers, Android devices, iPhones, a Chrome device, and a ‘helpful home device.’ Selecting any individual login, which Google calls a session, will reveal more details regarding the app or service and the type of information it has access to via your Google account.

3. Get rid of unnecessary connected devices

If you spot something odd, don't panic. You can select the option to ‘Sign out’ that device remotely. This severs the connection between that device or app and your Google account.

If you realize that you did, in fact, want to be signed into that app or device, reconnecting is as simple as signing in again. So, it’s better to err on the side of caution.

What to do if you have multiple Google Accounts

Your phone and other devices might be using more than one Google account. Maybe you have one account for personal use and another for work. It's convenient, sure, but it also means there are more accounts you need to keep an eye on.

On your Google Account webpage, click on your profile picture. Select another account, if you see it, or select 'Add another account' to log into your additional account(s).

This is a good time to check your password, too

Now that you have your linked devices under control, the next step is to make sure your passwords are secure. With the latest advances in GPU processing power for cracking passwords, that ‘strong’ password you crafted a few years ago may be much easier to hack than you think. Check out my story on NIST's current guidance for creating strong passwords, with a chart to evaluate your current password effectiveness.

Final thoughts

There you have it – a simple guide to keeping track of what’s linked to your Android phone. Make this a regular check-up, just like you would with your car or health, to ensure your personal information stays protected.
