Open your Google Account → Security and look for Your connections to third-party apps and services. Pick one app to see how it is connected. An app you use to sign in with Google and an app that can access your Google Drive data are different cases, even if both appear on the same page.
Review the connections on the right account
- Open Google’s third-party connections page and check the profile icon to confirm the Google account.
- Choose a service and read each connection or permission type. Check whether it uses Google for login, has access to account data, or is linked to another Google feature.
- For data access you no longer need, choose the option to remove access and confirm. For a sign-in or account link, choose the matching option only after reading what it will change.
Consult Google’s connection management guide if an app has multiple connections. Removing one type doesn’t necessarily remove the others. Repeat the review for other Google accounts you use.
Keep a way back into an app you still need
If Sign in with Google is your only route into a service, check whether the service supports a password, passkey or another login method before disconnecting it. Set up and verify that alternative in the service itself. For work accounts, a managed integration might be required; ask your administrator if you aren’t sure.
Know what revoking access does
Removing permission stops the app from using that connection going forward. It doesn’t automatically delete your separate account with the app, cancel a subscription or erase data the company already copied. Use the app’s own privacy or account controls for those actions. Some syncing workflows may stop, so check the service after the change if you still need it.
If the app looks unfamiliar, review your Google Account security activity as well. Start from Google’s own account page instead of a link in an unexpected message about a security problem.
