Breached Password Exposure Check
Verify whether a password has been compromised in breach datasets using a privacy-friendly k-anonymity query.
Reusing passwords across sites is common, but users rarely know if a specific password is in a public breach.
By hashing passwords locally and only querying a prefix, this tool tells you exposure risk without sending full credentials.
