Breach Monitor
Check which accounts may have appeared in data breaches and close the ones you no longer use.
Check Your Email Addresses for Breaches
Data from breaches can end up in broker databases, scam lists, or be reused by attackers. A leaked email and password from an old breach can still create risk today. Check every address you use.
- Add your email addresses above to keep track
- Click CHECK ON HIBP next to each one: opens HaveIBeenPwned.com
- HIBP shows every breach your address appears in
- For each breach: change that account's password, use a unique one via Bitwarden
- If you don't use the account anymore: delete it (see Account Graveyard below)
