Short answer
Can I check if my password is leaked without telling the AI the password?
Yes. The tool uses a k-anonymity model, meaning your AI only sends a partial hash to the service. You'll find out if your password was in a leak while your real password stays local to your machine. Here is what you'll get.
The outcomes
What you get from this check
The AI processes the safety check and delivers these specific results.
SECURITY
Breach status report
The AI identifies if your password matches any known leaked credentials. You'll see exactly which breaches your password was found in.
PRIVACY
Zero-knowledge verification
The tool ensures your plain-text password never leaves your local environment. Your AI only handles the necessary mathematical fragments.
ACTION
Risk assessment
Your agent evaluates the severity of the leak. It tells you if the compromise is critical enough to require an immediate change.
HUMAN
Manual remediation
The AI cannot change your passwords for you. You must manually update your credentials on the affected websites once a leak is confirmed.
The workflow
What your AI does when the check arrives.
Your AI handles the hashing and querying so you don't have to handle sensitive strings manually.
Hash the password
The AI takes your password and creates a partial hash. This ensures the full string is never transmitted over the internet.
check_password_safetyQuery the database
The agent sends the partial hash to the service to see if any matches exist in the leak database.
check_password_safetyAnalyze results
The AI looks at the returned data to determine if your password is part of a known breach.
check_password_safetyReport findings
Your agent summarizes the risk level and lists the specific breaches found.

How this task behaves
- 01
Does the AI see my actual password?
No. The tool uses k-anonymity to ensure only a partial hash is sent for comparison. Your full password stays private.
- 02
Can the AI change my passwords if they are leaked?
No. The AI can only report if a password is unsafe. You must go to the specific website and change the password yourself.
- 03
How does it protect my privacy during the check?
It uses a secure model where the service only receives a prefix of the hash, making it impossible to reverse-engineer your password.
- 04
Can I check an entire list of passwords at once?
No. The tool is designed to check specific passwords you provide in the prompt. It does not bulk-scan files or databases.
- 05
Will this tool tell me which website was breached?
Yes, if the password was part of a known leak, the AI will identify the source of the breach.
