The average person has dozens, sometimes hundreds, of online accounts: shops used once, apps tried and abandoned, forums, loyalty schemes. Each holds some personal data and often an old, reused password. You cannot stop companies being breached, but you can reduce how many hold your data. Closing old accounts is one of the simplest ways.

How to find old accounts

  • Search your email for "welcome", "confirm your email", "verify your account", "your order" and "unsubscribe".
  • Check saved passwords in your password manager and browser.
  • Review "Sign in with" connections in your Google, Apple and Facebook settings. See connected apps.
  • Check breach services: breaches listed for your email often reveal forgotten accounts. See checking breaches.
  • Look through old phones and app store purchase histories.

Decide: keep, secure or delete

Keep and secureDelete
Accounts you use regularlyShops you used once
Accounts with records you need (tax, health, purchases)Apps and games you abandoned
Accounts linked to important servicesOld forums and social networks
Duplicate accounts you made by mistake

How to delete properly

  1. Log in, using a password reset if needed.
  2. Download anything you want to keep.
  3. Remove saved cards and addresses.
  4. Find the delete or close option, usually under account, privacy or settings. If you cannot find it, search the service's help pages for "delete account".
  5. Request data deletion if your country's privacy law gives you that right.
  6. Remove the saved password from your password manager, or note it as closed.

Cannot delete it? At least change the password to a unique one, remove payment details, and turn off marketing.

Be careful with deletion emails

Scammers send fake "your account will be deleted" messages to get you to log in on fake pages. Always go to the site yourself.

Frequently asked questions

How do I find accounts I have forgotten?

Search your email for words like 'welcome', 'verify your email' and 'your account', check saved passwords in your password manager and browser, and review apps connected to your Google, Apple or Facebook sign-in.

Does deleting an account remove my data?

It should start deletion, but some companies keep certain data for a time for legal reasons. In many countries you can also request deletion under privacy law.

What if I cannot log in to an old account?

Use the password reset option. If the email or phone is no longer yours, contact the service's support, or at least remove any payment details if you can.
