Review Google Account Third-Party App Connections

How do you review third-party access to a Google Account?

Review each app's connection type, exact permissions and current purpose before changing anything. Google distinguishes sign-in, Google access to another service, and that service's access to Google data. Disconnecting is not proof of data deletion or subscription cancellation. Preserve access to accounts you still need; ask the provider or authorized administrator about uncertain dependencies. This review does not certify an app's privacy or security.

This is a desk-researched guide to Google's documented controls, checked in September 2026. No account was inspected or changed. Google's overview of linked apps establishes the different relationships. The worksheet below is an editorial planning tool, not an automated scanner.

Which connection are you actually reviewing?

Begin with the official Google connection-management guide, which links to the account's linked-apps page. Confirm that you are reviewing the intended account. Use its filters and details view to identify each relationship; an app can have more than one.

Google documents separate removal controls for these relationships. Do not assume one removed connection settles every relationship with the same app. Read the current details instead of treating the app's name as a complete permission description.

The direction matters. Google Account Linking lets Google use features of another service on your behalf. Google's example is playing music from a linked streaming account. That is different from a productivity app receiving access to your Google Calendar. Removing an account link can disable features that depend on it.

Does signing in give an app access to all your files?

No. Google describes Sign in with Google as sharing your name, email address and profile picture with permission, not your Google password. Additional Google-data access is a separate request.

That distinction belongs in the review record. “Uses Google” is too vague: it leaves unanswered whether the app merely uses that identity or also reads or modifies a Google service. Record the actual permission wording rather than guessing from a familiar logo.

For data access, Google distinguishes basic profile information, viewing or copying data, and managing data. Managing permission can include creating, editing or deleting information. Check the specific authorization: permission for one Google product is not automatically permission for every product. Never give an app your Google Account password to complete this review. Google's access-types explanation describes these boundaries.

What should go into a connection-review worksheet?

Start with a record you can fill without changing settings. Keep it private and follow workplace information-handling rules. Do not place passwords, recovery codes, access tokens, customer records or screenshots of sensitive account information in a shared planning document.

Use one row per relationship, not necessarily one row per app. The following fields are this publication's proposed review method:

Separate observation from inference. “The details display Calendar access” is an observation. “The team still uses this integration” requires confirmation from the responsible person. “Probably harmless” is neither a permission description nor evidence of a current need.

An empty purpose field is a reason to investigate, not a diagnosis of malicious behavior. An unresolved dependency is a reason to seek clarification, not a reason to grant more access. Keep those two decisions separate.

What does a completed example look like?

These are fictional records, not observations of real apps, permissions or user accounts.

Do not combine these into a single “three apps to delete” list. Each record asks a different question. The task planner has an account-entry dependency; the calendar board has a shared-workflow uncertainty; the audio service has a linked-feature dependency.

For the fictional calendar board, a useful handoff note would be: “Please confirm whether the shared planning view still depends on this connection. The review has not changed access. If it is still used, identify its owner and current purpose.” This asks for operational evidence without copying calendar contents into the note.

A reply such as “we stopped using it” resolves the purpose question only. It does not establish what data the provider retained, who pays for the subscription, or whether another connection exists. Keep those as separate fields.

What needs checking before any consequential change?

First, establish how you will access an app account you still need. Google's linked-app troubleshooting guidance warns that some apps do not support multiple sign-in methods for the same account. Contact the developer when that is unclear. Do not assume adding a password or choosing another button will reach the same records.

Second, identify who is authorized to change the connection. For work or school accounts, ask the responsible administrator about organizational requirements and shared dependencies. This guide is not permission to alter another person's account or bypass an administrative restriction.

Third, separate a routine review from a suspected compromise. If you suspect account intrusion, use Google's official compromised-account guidance, and notify your organization's security team where relevant. A worksheet is not an incident-response procedure.

For broader preparation, the App Trials collection covers evaluating tools before commitment. Use the Data Control collection for the separate tasks of preserving records and planning an exit. This connection review does not replace either task.

What remains unresolved after a connection is removed?

A removed permission and a deleted copy are different outcomes. Google's data-access guidance says an app may already hold copied information and that you may need to request its deletion from the developer. Google's data-sharing safety explanation also identifies provider retention policies as controlling how long information is stored. Review the provider's current privacy terms and deletion process rather than treating a disappeared connection as proof of erasure.

Keep billing in its own workstream: find the subscription's actual billing provider and its cancellation instructions. Do not mark a subscription cancelled because an account connection changed. Likewise, do not delete an app account merely to see whether the connection list updates; account deletion can destroy information you still need.

Close your review with an evidence note: what relationship you examined, what remains uncertain, who owns the next decision, and which provider documentation applies. If an authorized change is later made, record its observed result separately. A shorter connection list is not a privacy guarantee; the useful outcome is a clear account of access and unresolved obligations.
