Check if my password has been leaked?
The fastest and easiest way to check if your password(s) have been leaked is to check on haveibeenpwned.
Simply enter your email(s) and it will instantly tell you if it has been found in any data breaches.
LeakCheck lets you search for emails and usernames.
This one lets you search by password to see if your password itself is leaked.
Of course I'm sure there are better options out there, and if you know one feel free to tell me about it in a chat!
If your password is leaked, please change it to something secure. Its better to use a different password on each account.
