Audit Linked Apps on a Shared Household Account
Inventory linked apps, preserve essential automations, revoke unnecessary access, and leave every household integration with an owner and fallback.
Audit Linked Apps on a Shared Household Account
Review and remove linked apps before changing a shared household account, retiring an automation, or asking a resident to leave. A password change alone may not answer which outside services can still read or modify calendars, files, contacts, or other account data. Inventory each connection first, identify the household function it supports, then remove access that no longer has a named owner.
Separate three kinds of connection
Start by identifying what the outside service actually uses. “Connected app” can describe several different relationships:
- Federated sign-in: the household uses a provider button, such as Sign in with Google, to enter another service.
- Account linking: two services exchange information to provide a feature, such as playing a linked music service through a home assistant.
- Data access: an app has permission to view or manage a product such as Calendar, Drive, Photos, or Contacts.
These are not interchangeable. Google's linked-app management guide explains that removing a sign-in link stops automatic sign-in but does not delete data held by the outside app. It also warns that removing data access may make features unavailable. That is why a blind “remove everything” sweep can lock the household out of an appliance dashboard or silently stop a calendar automation.
Write down the connection name, access type, household purpose, current owner, and what should happen if it is removed. Do not copy tokens, passwords, or private data into the inventory.
Remove access in a safe order
Handle one connection at a time. First sign in directly to the outside service and make sure its recovery email, administrator, and payment owner are current. Export household data if the service provides a useful export. If the app controls a lock, alarm, thermostat, or accessibility routine, arrange a manual fallback before touching permissions.
Next, remove the connection from the identity provider's security or linked-app page. Then open the outside service and verify the result. It might remain as a separate account, require a new sign-in method, lose synchronization, or stop working entirely. Google's official explanation of third-party data access notes that revoking access prevents future account access, but the developer may retain data already copied. Contact the developer or use its deletion controls when existing data also needs to be erased.
Finally, record the outcome and test the household function. If a grocery list no longer appears on a kitchen display, that is a failed handoff even if the security page says access was removed.
Use least access for any reconnection
Reconnect only after deciding who owns the integration and what minimum permission it needs. A calendar display may need to read one household calendar, not every resident's mail and contacts. A photo frame should use a curated album, not a person's entire library. Avoid linking an individual's primary personal account when a purpose-built household account or delegated role is available.
Review the permission screen rather than treating it as a routine consent box. Google says linked apps can receive levels of access ranging from basic profile information to permission to view, copy, create, edit, or delete account data. If the request is broader than the household job, choose a narrower setup or leave the app disconnected.
HomeCo can carry the non-secret parts of this work: the integration name, owner, renewal date, and test result. Keep credentials in personal password managers or approved shared vaults. HomeCo's roommate digital privacy checklist can help residents review the surrounding devices and account boundaries.
Make departures and failures survivable
A connected-app register passes the Island Test when another resident can understand and safely operate the household after the original installer is unavailable. For every essential connection, answer four questions:
1. What stops working if access is revoked?
2. Who can administer the outside service?
3. Is there a manual way to operate the device or complete the task?
4. Where is the setup or recovery procedure stored?
Run the audit when a resident moves out, an automation is abandoned, a vendor reports a breach, or an app has not been used for several months. Also review it before deleting the identity account at the center of the setup. The goal is not maximum integration. It is a household where every active connection has a purpose, an owner, and a clean exit.
Frequently asked questions
Does removing a linked app delete its account and data?
Usually not. Removing the link stops or changes access between services. Use the outside app's own deletion process if you also want its stored account or copied data deleted.
Is changing the household account password enough?
Do not treat it as a complete linked-app review. Open the provider's connection or permission page and inspect active third-party relationships directly.
What should we record in HomeCo?
Record the app name, purpose, owner, review date, fallback, and test result. Never paste access tokens, recovery codes, or passwords into a general household task.
