Alternatives to Have I been leaked?

Send your own email address and it tells you whether that address has surfaced in a known data breach — a simple, unofficial Telegram front-end for the "have I been pwned" checking model. Never enter your actual password into it.

The Telegram bot of LeakCheck.io, a commercial breach-data search company operating since 2018 — check your own email or phone for free against their database. Its parent company also sells broader paid lookups, so treat the free bot strictly as a self-check tool.

A password-only breach checker that never sends your full password anywhere: it uses k-Anonymity (only a truncated SHA-1 hash prefix) against the Have I Been Pwned "Pwned Passwords" API, with open-source code so you can verify the claim yourself.

A Russian-language password checker: send it a password and it rates the strength, flags weak patterns like birthdays or keyboard walks, and checks it against 14+ billion breached passwords via k-Anonymity — the full password never leaves your device.
