How to See All Websites You’ve Created Accounts On

Over the years you’ve signed up for dozens of sites: stores, apps, forums, newsletters, tools, games. Each one created an account tied to your email address — and most of them are still out there.

The problem: You only remember a small fraction of them. The rest quietly store your data, reused passwords, and sometimes even payment details.

Why You’d Want a Full List

Method 1: Search Your Inbox for Clues

Your inbox is the most reliable list of where you’ve created accounts.

Try searching Gmail for:

This will surface many account registrations. But it’s still manual work, and you’ll miss a lot of services with generic subjects like “Notification” or “Security alert”.

Method 2: Check Your Password Manager

If you use a password manager or your browser’s saved passwords, you can see a list of sites you’ve logged in to.

Limitations: this only covers accounts where you actually saved the password.

Method 3: Use Google Account Permissions

For sites where you used “Continue with Google”, visit:

https://myaccount.google.com/permissions

This shows apps and websites connected to your Google Account, but it won’t include classic “email + password” accounts.

Why Manual Methods Miss So Much

Even after hours of manual searching, you’ll only find part of the picture. To see everything, you need automation.

Method 4: Automatically Discover All Websites Using Your Email

  3. Detects domains and services that have emailed you about accounts and logins.
  4. Groups them into a clean list of websites where you have an account.
