BreachAlert Intelligence

Detect compromised credentials and exposed identities across global data breaches.

Cryptographic Password Scanner

Securely check if a password has been compromised in a known data breach. We use K-Anonymity logic—meaning your actual password is never transmitted over the network.

Identity Exposure Portal

Check if your email address or phone number has been exposed in a major data breach (e.g., LinkedIn, Adobe, Canva leaks).

Due to strict privacy regulations, email lookup requires a verified API key. Layerbit guides you directly to the official Have I Been Pwned registry for a secure, ad-free verification.

How does the Password Scanner work without stealing your password?

Local Hashing: When you type a password, Layerbit uses the Web Crypto API to convert it into a SHA-1 cryptographic hash directly inside your browser.
Prefix Transmission: We extract only the first 5 characters of that hash and send it to the Have I Been Pwned API. It is mathematically impossible to reverse-engineer your password from just 5 characters of a hash.
Client-Side Matching: The API returns a list of hundreds of breached hash suffixes. Layerbit checks that list locally against the remainder of your hash. Your full password never leaves your device.
