# Breach Monitoring by User

Breach Monitoring by User allows you to subscribe specific email addresses (provided to Enzoic as SHA-256 hashes) for breach notifications.  Whenever login credentials for a monitored email address are found in an exposure, Enzoic will call a webhook on your end and/or send a notification email with the details.
