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.

Why You’d Want a Full List

• Security: Find old accounts with weak or reused passwords.
• Privacy: See who still stores your personal data.
• Control: Clean up accounts you don’t use anymore.
• Life events: Easier to manage when changing jobs, emails, or going through big transitions.

Method 1: Search Your Inbox for Clues

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

Try searching Gmail for:

• "welcome to"
• "verify your email"
• "confirm your account"
• "you've successfully signed up"

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

• You only search for what you can think of.
• Old emails are buried or archived.
• Some services rebrand and change names.
• Many registrations use generic subjects and senders.

Method 4: Automatically Discover All Websites Using Your Email

This is what WhoHasMyEmail is built for.

Our scanner:

1. Connects to your Gmail via secure Google OAuth (no password sharing).
2. Reads only email headers (From, Subject, Date) — never the message body.
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.

You receive:

• A professional PDF overview.
• An Excel file you can sort, filter and use as a cleanup checklist.

Turn the List into Action

Once you have the full list of websites you’ve created accounts on, you can:

• Close accounts you don’t need.
• Update passwords on important services.
• Remove saved cards and billing info on old stores.
• Reduce your digital footprint and risk exposure.
