What The Module Does
Required Email Verification is the email-only HERZA addon for WHMCS. It uses an emailed, six-digit, single-use OTP with a five-minute lifetime. The source includes resend limits, expiry checks, owner/session checks and CSRF protection. Existing native WHMCS owner verification can be recognized.
Who Verifies
The main account owner verifies their login email. Billing contacts are not independently required to complete this verification flow. This edition does not include telephone or SMS verification.
Current Edition
This guide describes the commercial development snapshot 0.1.0-dev. It is not a public Stable release or the Free Edition. The internal HERZA addon is a separate installation; do not treat this package as an in-place update.
Administrator onboarding, commercial licensing and full customer upgrade/rollback qualification remain release work. Third-party API, mobile and purchase integrations need their own compatibility validation.
Next Steps
