Breach Check Password

by NetIntel in Security & trust

x402 APIPassing, checked 50 min ago

Check if a password has appeared in known data breaches using the HaveIBeenPwned Pwned Passwords API with k-anonymity — the full password is never transmitted, only a 5-character SHA-1 hash prefix — returns breach count and a risk classification so agents can enforce password policies without storing or exposing credentials.
