To manage apps by mobile device operating system, go here.
You can control which third-party and domain-owned apps can access sensitive Google Workspace data. App access control governs access to Google Workspace services using OAuth 2.0. To facilitate app access, modern, more secure apps use OAuth 2.0 scopes—a mechanism to limit an application's access to a user's account. These scopes help provide access to limited user data from most Google Workspace services, such as Gmail, Google Drive, Calendar, and Contacts. Use app access control to:
- Restrict access to most Google Workspace services or leave them unrestricted.
- Trust specific apps so they can access restricted Google Workspace services.
- Trust all domain-owned apps.
To control which third-party and internal apps can access Google Workspace data, and to find details about any third-party apps already in use, follow the instructions below. You can also customize the error message users see when they try to install an unauthorized app.
Use app access control
Before implementing controls, review the list of apps that have been authorized to access Google Workspace data.
Note: Details about third-party apps typically appear in results within 24–48 hours.

- Verified status—Verified apps have been reviewed by Google to ensure compliance with certain policies. Note that many well-known apps might not be verified in this way. For more details, see What is a verified third-party app?
- Users—Number of users accessing the app.
- Requested services—Google service APIs (OAuth2 scopes) that each app is using (for example, Gmail, Calendar, or Drive). Services not shown in the GOOGLE SERVICES tab are listed as Other.
- Access—Specifies Trusted, Limited, or Blocked.
- Click the table row of an app to open the app details page. From this page you can do the following:
- View or change whether or not your app can access Google services—Review whether the app is marked as Trusted, Limited, or Blocked. If you change the access configuration, click SAVE.
- View information about the app—This includes the full OAuth2 client ID of the app, number of users, privacy policy, and support information.
- View the Google service APIs (OAuth scopes) that the app is requesting—From the Requested Services section of the app details page, you can view a list of OAuth scopes that each app is requesting. To see each of the OAuth scopes, be sure to expand the table row, or click EXPAND ALL.
- (Optional) Download app information.
You can download all of the information in the app table by clicking Download app info. This downloads app metadata that's listed in all pages in the table to a CSV file.
App verification is Google’s program to ensure that third-party apps accessing sensitive customer data pass security and privacy checks. Users may be blocked from activating unverified apps that you don’t trust (see details on trusting apps below). For more information on app verification, see Authorize unverified third-party apps.
You can restrict (or leave unrestricted) access to most Google Workspace services, including Google Cloud services such as Machine Learning. For Gmail and Google Drive, you can specifically restrict access to high-risk scopes (for example, sending Gmail or deleting files in Drive). While users are prompted to consent to apps, if an app uses restricted scopes and you haven’t specifically trusted it, users can’t add it.

From the App Access Control page, you can manage access to certain apps by blocking those apps, marking them as trusted, or providing access only to unrestricted Google services.
Trust specific apps that you want accessing all Google Workspace services (OAuth scopes), or you can decide to trust all domain-owned apps. Trusting apps also ensures that users can install apps that are unverified by our counter-abuse team. Apps that you don’t trust have limited access to Google Workspace APIs—they can only access unrestricted services. You also have the option to block apps so they can't access any Google Workspace service.
Tip: Users are prompted to consent to add web apps, but on Google Workspace Marketplace, for approved apps only, you can bypass the consent screen through domain installation.

From the API controls page, you can block all third-party API access. By using this powerful control, requests by third-party apps and websites are denied access to user data. This setting blocks all OAuth scopes, including sign-in scopes, meaning that users will no longer be able to sign in with Google to third-party apps and websites.
Important: Users will have access to explicitly trusted apps and trusted domain-owned apps even when you enable the Block all third-party API access setting. For more details about trusted apps, see Manage access to apps: Trusted, Limited, or Blocked and Let internal apps access restricted Google Workspace APIs.
