Captcha Form Protection

Also known as image verification; shows an image containing letters and numbers that only humans can read on the ticket submission, registration and domain checker pages to help prevents automated submissions and spam. You can select whether the image verification is never displayed, always displayed or only displayed to visitors.

Captcha Type

Default Requires GD2 on your server. Shows an image containing 5 characters on a blue stripped background, no further configuration is required. reCAPTCHA Uses Google's reCAPTCHA[1] service. You will need to register for a set of keys to use this service, this can be done here. Once you have your keys, you can enter them in the appropriate boxes on this tab. There are some additional configurations that can be done using the reCAPTCHA option, please see reCAPTCHA for more details.

Required Password Strength

Set to 0 to disable the password strength checker on the order form. Ensure your clients enter strong passwords by setting this to 50; use a higher number to force even more secure client area passwords.

For a password strength of 90 the user would be required to enter at least 3 numbers, 2 lowercase & 3 uppercase letters and 3 special characters. More detailed information can be found by reviewing the includes/jscript/pwstrength.js file.

Failed Admin Login Ban Time

Set to 0 to disable the login ban feature. If someone makes 3 incorrect attempts to login to your WHMCS admin, this is the time in minutes before they can try to login again (dictionary attack protection). How to unban your IP if it becomes blocked.

Whitelisted IPs

The IP addresses listed here will never be banned from accessing the admin area due to login failures. For example you may wish to add your office IP address.

Admin Force SSL Access

When unticked the administration area can be access via both http and https connections. Ticking this option forces all connections to use https for increased security.

Disable Admin Password Reset

When checked, this will disable the Forgotten Password link on your Admin Login page. This replaces any previous method of disabling this option.
How to reset the admin password with this option disabled.

Disable Credit Card Storage

By default a client's credit card number is encrypted and stored in your database. Enabling this option means the number will not be stored and clients will need to re-enter their number for each invoice they pay.

Note: When using a tokanisation payment gateway type this option should remain unticked so the card details are stored on the remote server. The full card details will not be stored on your server.

Note: If credit card information is currently stored inside your WHMCS database, ticking this option will clear all existing credit card details from the system, including the gateway id (used by tokanisation gateways).

Allow Customers CC Delete

When unticked only admins can remove credit card details from a client's account. When ticked, an option will appear in the client area for the same.

Disable MD5 Clients Password

For security client area passwords are irreversibly encrypted and cannot be viewed by admins, enabling this option will switch to reversible encryption allowing admins to view the password. When switching from irreversible to reversible clients will all be assigned a new password and will need to use password recovery. This will change the way the "Reset & Resend Password" links behave in the client's profile; instead of generating a new password, the existing password will be emailed to the client.

Disable Session IP Check

This is used to protect against cookie/session hijacking and ideally should remain unticked. However it can cause problems for users with dynamic IPs or using mobile devices (iPhones etc) so can be disabled by ticking the checkbox.

Trusted Proxy Settings

The Trusted Proxies setting allows you to itemize IP addresses or IP ranges for proxies or other forwarding services so that WHMCS can accurately determine the IP address of inbound traffic.

You may find it necessary to utilize the Trusted Proxy settings if your WHMCS installation:

• is behind a proxy you control
• is behind a load balancer or firewall that modifies HTTP requests
• receives HTTP requests from a proxy or DDOS protection service, such as CloudFlare, BlackLotus, etc
• is behind most any infrastructure which has the responsibility of modifying the information the link layer of a request.

These types of deployment setups will alter the value from the originating IP address to their own IP. This is expected behaviour as it is part of standard network specifications. Unfortunately there’s a side effect; it makes it look as if your client logins, admin logins, and orders are all coming from the proxy instead of the real location. When this happens, the location is masked from your inspection, be it for logging, access authorization, fraud detection, or any other IP related purposes. To counteract this, the details of your proxy service can be entered into these fields. Further Reading >>

Proxy IP Header

The Proxy Header field allows you to configure the HTTP header WHMCS will use to figure out which IP address is the authoritative IP address for the request.

Most proxies use "X_FORWARDED_FOR" and so the field can be left blank. Only change this value if you are sure your proxy uses a different header, as putting the wrong header into this field can cause improper recording of IP addresses.

Trusted Proxies

Use this field to add and remove IP Addresses and IP Address CIDR ranges of trusted proxies. WHMCS will check the header configured to discover the actual canonical request IP address.

API IP Access Restriction

Advanced. If using the WHMCS API from an off-server location, you must specify the IP address here, otherwise access will be denied.

Log API Authentication

By default successful authentications made via the API are not recorded, but ticking this option will record them with admin area authentications under Utilities > Logs > Admin Log. This might be useful for recording logins from your staff using our mobile apps.

CSRF Tokens

This additional security feature prevents malicious visitors to your website forging form posts to try and access parts of the software they should not. This option is set to "Enabled" by default and we recommend keeping it on, unless specifically advised otherwise my a member of WHMCS staff.

CSRF Tokens: Domain Checker

By default CSRF tokens are disabled for the domain checker. This allows you to send domain information to WHMCS from an external page. Eg. using the Domain Checker Integration Code on your website.

However if you are not using the integration code, you can enable this option and visitors will only be able to use the built-in domain checker pages.
