How Do You Find All The Sites My Email Is Registered To?

If your inbox is overflowing with forgotten sign-ups or you’re concerned about old linked accounts, here’s how to tidy things up quickly.

Quick Fix Summary
Head to myaccount.google.com → Security → Third-party access → Manage access. Pull the plug on anything sketchy. For Outlook, try Settings → Mail → Accounts → Connected accounts. In Gmail’s mobile app, tap your profile icon → “Manage your Google Account” → Security → Third-party access.

What’s really going on here?

Over the years, your email address ends up attached to apps, services, and websites—often without you noticing. Those “linked” accounts can be risky if they’re old or unfamiliar. Google and Microsoft keep beefing up their security dashboards, so auditing these connections gets easier straight from your account settings Google Support.

Let’s fix this step by step

For Google (Gmail) accounts

  1. Fire up a browser and head to myaccount.google.com.
  2. Sign in when asked.
  3. On the left sidebar, click Security.
  4. Scroll down to Third-party access and hit Manage access.
  5. Look through the list under “Apps and services connected to your account.”
  6. Click Remove next to anything you no longer use or trust.

For Microsoft Outlook accounts

  1. Log in to outlook.com.
  2. Click the gear icon (top right) → Settings.
  3. Under Mail, pick AccountsConnected accounts.
  4. Scan the list. If something looks off, click Remove.

For Gmail on your phone

  1. Open the Gmail app and tap your profile picture (top right).
  2. Tap Manage your Google Account.
  3. Go to SecurityThird-party access.
  4. Hit Manage access and shut down any apps you don’t want.

What if nothing changes after I revoke access?

  • Try a privacy-first helper: justdeleteme.xyz lists direct deletion links for services tied to your email. It’s manual, but the list stays current as of 2026 JustDeleteMe.
  • Dig through your inbox: Run Gmail’s advanced search: has:link OR has:account. Scan the results for account-confirmation emails.
  • Peek at your browser’s password vault: Open Chrome, Edge, or Firefox → Settings → Passwords → Saved passwords. Hunt for sites where your email is the login.

How can I keep this from happening again?

  • Never reuse passwords: Each site should get its own unique password. A password manager like Bitwarden or 1Password can generate and store rock-solid passwords Bitwarden Help.
  • Turn on two-factor authentication (2FA): Enable 2FA for your email and any important accounts. Google and Microsoft support authenticator apps and hardware keys Google 2FA.
  • Schedule a monthly cleanup: Set a calendar reminder to review connected apps every 30 days. Most breaches start with forgotten third-party integrations CISA.
  • Skip social logins for sensitive sites: Sure, it’s quick, but signing in with Google or Facebook adds another account to your email trail. Use a direct email/password combo for banking or medical portals.

Cleaning up your digital footprint isn’t a one-and-done chore—it’s ongoing upkeep. Start in the security dashboard, clear out what you can, then build habits to stay on top of it.
