DeHashed
Search engine over billions of breached credentials and personal records.
DeHashed is a search engine that indexes billions of breached credentials and personal records from data leaks. It allows researchers to verify if specific email addresses or usernames have been compromised in known security incidents. This tool is typically used for legitimate threat intelligence and monitoring purposes to assess exposure risks.
Dual-use tool. This is capable of legitimate research (journalism, security, due diligence) and of harassment or stalking. Listing it here is not an endorsement of either use.
Privacy note. Assume any password in a past breach is public — check and rotate yours.
