How to see every app connected to your Google account
"Sign in with Google" is convenient: one click and you have a new account. After a few years, dozens of apps and websites can be connected to your Google account, some with access to your profile, some with access to your Gmail, Drive or contacts. Here is how to see all of them, remove the ones you no longer use, and find the accounts Google does not list.
Step 1: open your Google connections page
Go to myaccount.google.com, open the Security tab and scroll to Your connections to third-party apps & services. Click See all connections. On a phone, the same page is in the Google app under Manage your Google Account, then Security.
The list shows every app or site that you signed in to with Google, or that you gave access to some of your Google data. Click any entry to see when the connection was made and exactly what it can access.
Step 2: read what each app can access
Each connection falls into one of two groups:
- Sign in with Google only: the site knows your name, your email address and your profile picture. Low risk, but it is still an account holding your data.
- Access to your Google data: the app can read or change things in Gmail, Drive, Calendar, Contacts or Photos. These deserve a close look, especially if the access includes Gmail.
Be most careful with apps that can read, send or delete your email. Some free email tools have historically sold insights from their users' inboxes. If you do not recognise an app or no longer use it, remove it.
Step 3: remove the access you no longer need
Open the connection and click Delete all connections you have with the app, or Stop using Sign in with Google. The app immediately loses access to your Google data.
Removing the connection does not delete your account on that service, and it does not delete the data it already collected. If you want that gone too, log in to the service and delete your account there, or send a GDPR erasure request. Our guide on deleting old online accounts has a ready-to-paste template.
Step 4: find the accounts Google does not list
The connections page only covers apps that used Google sign-in. Every account you created with your email address and a password is missing from it, and that is usually the majority: online shops, newsletters, forums, travel sites, utilities.
Those accounts left a trace in your inbox instead. In Gmail, search for subject:(welcome OR "confirm your email" OR "verify your email") to find sign-up confirmations, and subject:("reset your password") to find the accounts you logged in to again later. Our guide to finding all accounts linked to your email covers more searches.
How often should you check?
Once or twice a year is enough for most people. Do it right away if you get a security alert from Google, if an app you connected is in the news for a data breach, or if you stop using a service that had access to your Gmail.
Google only shows half the picture. HealthInbox lists every service tied to your Gmail address, including the ones you signed up for with a password, privately and on your device.
