Start with central accounts
Fictional example: after leaving a club, Sofia finds an old shared folder in her private cloud account. She first checks ownership and whether the club still needs the documents. She arranges a handover rather than deleting the whole folder without consultation.
Begin with primary email, device-platform accounts, cloud storage and important payment services. Add others as necessary. A private overview needs service, purpose, responsible person and next action, not a collection of every password. Investigate unfamiliar entries instead of assuming they are irrelevant.
Secure recovery before making changes
Check that registered phone numbers and email addresses still work for you. An old work email is not a reliable permanent alternative when you no longer control it. Update information through official processes and confirm new contact routes where required.
Review supported extra sign-in methods and protected storage of recovery options. Do not remove an old device before establishing whether it is your only usable access route. Make changes gradually so you can identify a problem and obtain assistance before losing more access.
Distinguish devices from permissions
A device session, shared file and connected application represent different forms of access. Check who owns each permission and why it remains necessary. An unfamiliar name on your own renamed device should not be treated as confirmed access by a stranger.
Google distinguishes app sign-in, linked accounts and access to account data, for example. Read the individual description. Removing a sign-in connection may affect entry into another app. Establish a supported alternative with that provider before revoking the connection you currently use.
Coordinate closure with data and obligations
Before closing an account, examine needed documents, shared content, subscriptions and recovery dependencies at other services. Export required information using the provided process and check readability. Downloading a file does not automatically preserve every item or recreate the original sharing arrangements.
Revoking an app’s permission does not necessarily remove information the other provider already holds. Account deletion and contract termination have separate processes. Read current guidance and ask about unclear consequences. This article does not replace individual advice about legal retention or contractual obligations.
Keep a small change log
Sofia records which sharing ended, which contact details changed and which handover remains open. After important changes she confirms that her own access still works. A short follow-up appointment covers unresolved items rather than repeating every completed step.
Confirmed unauthorised activity requires the appropriate security and recovery process, not ordinary annual housekeeping. Otherwise, aim for deliberate, checkable changes. A fully ticked account list does not prove absolute security; it records which questions you actually examined at a particular time.

Common questions
Must I replace every password each year?
This plan does not require blanket changes without a reason. Use strong unique passwords and replace affected credentials when exposed, reused or indicated by provider guidance.
Does disconnecting an app delete my information there?
Not automatically. Google distinguishes removing connections from deleting account data. Review the other provider’s own privacy and deletion controls.
Can I simply turn off an old email address?
First update important sign-ins, contact routes and recovery arrangements. Otherwise, confirmations or account recovery messages may continue going to an address you cannot reach.
