Management

Anti-Fraud & Email Verification For WHMCS lets you control when clients must confirm their email addresses and provides tools to manage the complete verification lifecycle. In this guide, we will walk you through every section and option of the module in detail.

Dashboard

The dashboard provides an overview of recent verification and anti-fraud activity. The 'Anti-Fraud Activity Summary' shows the numbers of failed verification attempts, rate-limited requests, automatic blocklist entries, failed CAPTCHA challenges and resent verification emails recorded today, during the last 7 days and during the last 30 days. The 'Verifications Over Time' chart compares verified and unverified records from the last 30 days, helping you identify recent activity and trends.

Verifications

The 'Verifications' section contains all email verification records created by the module. Five counters provide a quick overview: Pending - verification has been initiated but not yet completed. Verified - the email address has been successfully verified. Rejected - the verification attempt has been rejected. Expired - the verification link or code is no longer valid. Total - the total number of verification records. Press 'Show' on a counter to filter the table by the selected status.

The table lists: Email - the email address used for verification. Status - 'Pending', 'Verified', 'Rejected' or 'Expired'. Created At - when the verification was initiated. Verified At - when the email address was verified; 'Never' is shown if verification has not been completed. Expires At - when the verification link or code expires. Use the search field to find a record. The row actions allow you to mark it as unverified or delete it.

Mark As Unverified

Press the 'Mark As Unverified' icon to return a record to 'Pending', then confirm the action. Important: This changes the verification status only. It does not undo any order or account action already taken while the address was considered verified.

Delete Verification Record

Press the trash bin icon to permanently remove the selected verification record. The related WHMCS client account and order, if any, remain unaffected. This action cannot be undone.

Blocklist

The 'Blocklist' prevents selected email addresses, IP addresses and complete email domains from using the verification process. Entries may be added manually or created automatically after the configured number of failed attempts is reached.

The table includes: Type - email address, IP address or email domain. Value - the blocked value. Source - 'Manual' or 'Automatic'. Reason - an optional internal explanation. Expires At - the expiration date; 'Never' indicates a permanent block. Created At - when the entry was created. Press the eye icon to view the complete reason when it is shortened in the table. Use the trash bin icon to delete an entry.

Add Blocked Entry

Press 'Add Blocked Entry' and configure: Type - select 'Email', 'IP Address' or 'Email Domain'. Value - enter a value matching the selected type. Reason (Optional) - enter an internal note explaining the entry. Expires At (Optional) - select an expiration date or leave the field empty to create a permanent block. Press 'Confirm' to add the entry.

Settings

The 'Settings' section controls the verification workflow, reminders, account lifecycle and anti-fraud protection. The options are divided into four panels. Press 'Submit' to save the configuration.

Verification Mode

Verification Mode - choose where verification is required: All Pages - locks the entire client area until verification is completed. Checkout - prevents an unverified client from placing an order. Verification Delivery - choose 'Clickable Link' or 'Code To Type In'. Token Validity (Days) - define how long the generated verification link or code remains valid.

Reminders

Reminder After (Days) - send a reminder email after the client has remained unverified for the specified number of days. Enter 0 to disable reminders. Resend Cooldown (Minutes) - the minimum wait before another verification email can be requested.

Account Lifecycle

These options automate actions against client accounts that remain unverified: Auto-Inactivate After (Days) - set the client account to 'Inactive' after it has remained unverified for the specified number of days. Enter 0 to disable this action. Auto-Terminate After (Days) - permanently and irreversibly delete the client account and all of its WHMCS data after the specified number of unverified days. Enter 0 to disable this action. Auto-Delete Unverified Accounts - enable automatic cleanup of unverified accounts without active orders. Auto-Delete After (Days) - define the delay after Auto-Terminate before an eligible account is closed. Important: Auto-Terminate actions are permanent and irreversible and may remove the client account together with all related WHMCS data. Review these settings carefully before enabling them in production.

Rate Limiting & Anti-Fraud

Rate Limit: Max Attempts - the maximum attempts allowed within the configured window. Rate Limit: Window (Minutes) - the rolling period used to count verification attempts. Auto-Ban After Failed Attempts - automatically block the related email address and IP address after this many failures. Enter 0 to disable it. Auto-Ban Window (Minutes) - the rolling period used to count failed attempts for automatic bans. Enable Captcha Verification - require a CAPTCHA challenge during email verification. The module uses the CAPTCHA type and credentials configured in WHMCS. Before enabling this option, go to 'System Settings' → 'General Settings' → 'Security' in WHMCS and configure CAPTCHA. Important: If CAPTCHA verification is enabled in the module but CAPTCHA has not been configured correctly in WHMCS, clients will encounter an error when attempting to complete verification.

Client Area

When verification is required, the client sees the 'Email Verification' page with the account email address. The exact verification flow depends on the selected delivery method. The client can press 'Resend' to request another verification email after the configured cooldown period.

The available flows are: Clickable Link - open the link received in the verification email and complete any required CAPTCHA challenge. Code To Type In - enter the code received in the verification email in the form and press 'Verify'. If 'Enable Captcha Verification' is active, the CAPTCHA configured in WHMCS is also displayed. After successful verification, the client can continue to the restricted page or complete checkout.

The verification email contains either a clickable verification link or a one-time code, depending on the selected delivery method.

If an unverified client attempts to place an order while 'Checkout' mode is enabled, WHMCS prevents the order from being completed and asks the client to verify the email address first.

Access Control

The 'Access Control' tool allows you to restrict administrator access to individual module sections and actions. Create rules and assign them to selected administrators or administrator roles. For each rule, define the resources that should be available or restricted.

The 'Resources' tab lists the module resources available for access rules. Use the switches in the 'Log' column to decide which resource actions should be recorded in the access control logs. For detailed instructions, see the dedicated Access Control documentation.

Logs

The "Logs" tool makes monitoring and managing module activity records simple and efficient. It provides options to categorize, filter and view detailed entries, giving you control over the logs. For detailed guidance, check its dedicated article, available here.

Themes

The 'Themes' tool allows you to customize the appearance of the module interface in the admin and client areas. Create a new theme or activate an existing one separately for each area. The module includes the officially supported 'Default' and 'Dark' themes.

The following screen presents the module dashboard with the officially supported 'Dark' theme enabled.

Tips

1. Test every verification flow before applying restrictions to all clients. Use a test account to check the selected delivery method, email content, CAPTCHA challenge and redirect behavior.

2. Use reminders and account inactivation before enabling permanent account removal. This gives legitimate clients additional time to complete verification and reduces the risk of unintended data loss.

3. Set a resend cooldown and reasonable rate limits. These measures reduce repeated email requests while allowing legitimate clients to try again after a short wait.

4. Review the blocklist and logs regularly. Check automatically created entries and repeated failures before removing a block or changing the anti-fraud thresholds.

Update Instructions

An essential guide to updating the module is available here. Follow every step carefully to prevent data loss or other unexpected issues.

Common Problems

1. The client does not receive the verification email. Check the module and WHMCS mail logs, verify the mail configuration and ask the client to check the spam folder. Wait until the 'Resend Cooldown' ends before trying again.

2. The verification link or code is rejected. The verification details may have expired, already been used or may not match the pending record. Request a new message and use the newest link or code within its validity period.

3. The client cannot request another verification email. The resend cooldown or rate limit may have been reached. Wait until the relevant window ends or review the limits under 'Settings'.

4. A legitimate client cannot complete verification. The client's email address, domain or IP address may be on the blocklist. Review 'Blocklist' and 'Logs', then remove the entry only after confirming the request is legitimate.

5. CAPTCHA verification fails. Go to 'System Settings' → 'General Settings' → 'Security' and confirm that CAPTCHA has been configured correctly in WHMCS before enabling it in the module.
