Google Password Checkup vs an email breach checker: what each one covers
2 min read · Updated November 8, 2026
Google Password Checkup tells you whether passwords saved in your Google account are known to be compromised. An email breach checker tells you whether your email address appears in known breaches. They answer different questions, so using both gives a fuller picture.
What Google Password Checkup does
It compares the passwords saved in your Google password manager against lists of known leaked credentials and flags passwords that are compromised, reused or weak. It only covers credentials you have saved there.
What an email breach checker does
It looks up your email address in breach records and shows which incidents included it and what kinds of data were exposed. It does not need your passwords and covers accounts you never saved in a password manager.

Where each one falls short
- ✓Password checkups miss accounts whose passwords are not saved with that tool.
- ✓Email checkers do not tell you which of your current passwords are weak.
- ✓Neither can see breaches that were never published as searchable data.
Using them together
- ✓Run the email check to learn which services leaked your address.
- ✓Open your password manager’s security report and fix compromised or reused passwords.
- ✓Turn on two-factor authentication for important accounts, starting with email.
Frequently asked questions
Does Google Password Checkup show if my email was in a breach?+
Not directly. It checks saved passwords, not your email address against breach records.
Do I need both?+
They overlap partly but not fully. The email check shows where you were exposed, and the password checkup shows which saved passwords to change.
Is either one a guarantee?+
No. Both rely on known data, so a clean result is useful but not proof that nothing leaked.
Stop guessing. Check your email in seconds.
The Leakill scan looks for your email address in known breach records and delivers a detailed report: the incidents, dates, sources, the kinds of data involved and practical next steps. It is a one-time $1.99 payment, not a subscription.
A breach match is a warning signal, not proof that someone has access to your account today. No public database covers every breach, so a clean result lowers risk without guaranteeing safety.
