Checking breaches for 'test@example.com'... I found 3 breaches: Adobe (2013), LinkedIn (2016), and Canva (2019). Leaked data includes: Email addresses, Passwords, Usernames.

Is the password 'P@ssword123' safe to use?

⚠️ **DANGER!** This password has appeared in **45,210** data breaches. You should **NEVER** use this password as it is easily guessable and publicly known.

Yes. This agent uses the K-Anonymity model. Only the first 5 characters of your password's SHA-1 hash are sent to the HIBP server. The full password or full hash never leaves your local environment, making it cryptographically safe.
