Has your password already leaked?
Attackers don't guess passwords — they reuse ones already leaked in breaches. If your password is on a public list, every account using it is one automated attempt from takeover.
DARKSHARE checks the password against billions of leaked credentials using a privacy-preserving method, so you learn if it's exposed without ever revealing it.

- ✓Breach exposure — whether this exact password appears in known credential dumps.
- ✓Exposure frequency — how often it has been seen (common passwords are tried first).
- ✓Strength signals — patterns that make it trivial to crack.
- ✓Reuse guidance — why a leaked password must be retired everywhere.
Data sources we cross-reference
We cross-reference 10+ specialised sources (of 176+ total).
How the 0–100 risk score works
Any appearance in a breach is high risk regardless of complexity — known passwords are the first thing attackers try. Frequency and weakness push it higher.
Frequently asked questions
Do you see my actual password?
No. We use a k-anonymity range check: only a short hash prefix leaves your device, never the password itself.
My password leaked — what now?
Stop using it everywhere immediately, set a unique strong password per account, and turn on two-factor authentication.
Is a complex password safe if it leaked?
No. Once a password is in a public dump, complexity is irrelevant — attackers just look it up.
