LeakCheck vs Password Audit Bot
For most people, LeakCheck (@LeakCheck1_Bot) is the better first check: it tells you for free whether your own email address or phone number appears in the breach database of LeakCheck.io, a commercial company that has run breach searches since 2018. The company also sells broader paid lookups, so use the free bot for your own data only. Password Audit Bot (@passwordaudit_bot) answers a different question: whether a specific password is already on Have I Been Pwned's Pwned Passwords list, and per its open-source code it sends that API only the first five characters of the password's SHA-1 hash. Pick Password Audit Bot when you want to know whether a password you reuse is already exposed.
