To see what devices are logged into your Google account, go to myaccount.google.com, open the Security section, and select "Your devices," or on Android open Settings, tap Google, then Manage your Google Account. You will see every phone, tablet, and computer signed in. From there you can review each one and sign out any device you do not recognize.
Why this happens
Your Google account stays signed in on every device where you logged in and did not sign out, which is convenient but worth checking. You might see extra devices because:
- Old phones or computers you no longer use are still signed in.
- You logged in on someone else's device or a public computer and forgot to sign out.
- A browser or app kept a session active after an update or reinstall.
- In rare cases, someone else has your password and is signed in without your knowledge.
Is this normal?
Seeing several of your own devices is completely normal, including ones listed more than once for different browsers or apps. What is not normal is a device, location, or browser you do not recognize.
Does it cause any problems?
Your own signed-in devices are fine. An unknown signed-in device is a problem, because that person could read your email, reset other passwords, and access your files. If you see one, treat it as a possible account breach.
How to fix or check it
- On any browser, go to myaccount.google.com and sign in, then open Security from the left menu.
- Scroll to "Your devices" and click "Manage all devices" to see the full list.
- On Android, open Settings, tap Google, then "Manage your Google Account," swipe to Security, and find "Your devices."
- On iPhone, open the Gmail or Google app, tap your profile picture, choose "Manage your Google Account," then Security, then "Your devices."
- Tap any device to see the last activity, browser, and approximate location. If you do not recognize it, select "Sign out."
- If you signed out an unknown device, immediately change your Google password and turn on two-factor authentication, also called 2-Step Verification.
- For extra safety, review "Third-party apps with account access" in the Security section and remove anything you no longer use.
Frequently asked questions
Why does the same device appear twice?
Google often lists separate sessions for different apps and browsers on one device, such as Chrome and the Gmail app. This is normal. The details screen shows which app or browser each entry belongs to.
What happens when I sign out a device remotely?
That device is logged out of your Google account and must enter your password to sign back in. If it is your own device you still use, you will simply log in again.
Does signing out a device stop a hacker?
It ends their current session, but if they know your password they can log back in. Always follow up by changing your password and enabling two-factor authentication.
