# Fix Google Sheets Connection Issues

> Learn how to fix Google Sheets authentication errors in LanderLab by removing the linked app from your Google account and reconnecting.

##

Some users may see a warning that the Google Sheets integration is not safe, or run into errors during authentication. This usually happens when a previous connection between LanderLab and your Google account was not completed properly or became stale.

The fix is to remove LanderLab from your Google account's linked apps and then reconnect it from scratch.

<Steps>
  <Step title="Open Your Google Account Settings">
    Go to [myaccount.google.com](https://myaccount.google.com/) and sign in with the same Google account you use for the integration.
  </Step>

  <Step title="Go to Linked Apps">
    In the left sidebar, click **Security**, then scroll down to the **Your connections to third-party apps & services** section. Click **See all connections** to view the full list.
  </Step>

  <Step title="Find and Remove LanderLab">
    Search for **LanderLab** (or **landerlab.io**) in the list. Click on it, then click **Delete all connections** to remove all permissions. Confirm the removal when prompted.
  </Step>

  <Step title="Reconnect in LanderLab">
    Go back to your landing page in LanderLab, open the integrations panel, and add the Google Sheets integration again. You will go through the authentication and permissions flow as if connecting for the first time. This creates a fresh, clean connection.
  </Step>
</Steps>

After reconnecting, the warning should no longer appear and the integration will work as expected.
