You may also access Castlight via your iPhone or Android phone, by downloading the free Castlight mobile app through your app store, or by visiting www.mycastlight.com/mobile.

Yes. Each Castlight user must have a separate email address. Your email address serves as your username when logging in and must be unique within the Castlight system. Your own email address also allows you to receive personalized alerts and updates.

Often this means your information is not up to date in your Human Resources system. Did you move recently? You may be entering your current zip code in Castlight, but your company or HR team may still have your old address on file. Contact your HR department to update the information in your medical plan and benefits. Also, be sure to double check that you’re entering your personal information correctly.

First, you need to make sure you are on a plan that is Castlight-eligible. Castlight does not support all plans. If your plan is eligible for Castlight, your plan and benefits may not activate until the first of January of the coming year. Once your plan and benefits activate, you will be able to register. Keep in mind that Castlight is not available to dependents under the age of 18.

We encourage you to submit your personal information as soon as you become eligible for Castlight. You will be able to access your account when your plan and benefits are active. You will receive an email from Castlight when your account is ready.

accessing castlight

Castlight will alert you whenever we update your claims history, and we'll occasionally send you personalized health recommendations and product updates. We also use email to communicate with you when you make changes to your account (e.g., to confirm a password change). If you feel like you’re hearing from us too often, you can easily change your Castlight email preferences on your account page.

Castlight’s mobile app works on most devices. An application is available for iOS and Android devices. Download the app for free from the Apple App Store or Google Play. For other devices, you can access Castlight through your phone’s web browser. Start using the mobile app today by visiting www.mycastlight.com/mobile.

Castlight is compatible with all major browsers, including Chrome, Mozilla, Safari, Internet Explorer11 and Edge. We recommend always using the latest version of your browser. Please note that Internet Explorer, versions 10 or earlier, may experience issues loading Castlight.

Since Castlight is personalized for your health plan and benefits information, we need to create a new account for you when you change employers. This means that you’ll have to register for Castlight with a new email address.

privacy and security

Your employer has partnered with Castlight Health to keep your healthcare information private and secure. Your personal activities in Castlight are not shared with your employer. Castlight has partnered with VeriSign to ensure adherence to some of the industry’s strictest security standards. We also keep your data safe in accordance with federal HIPAA guidelines. For more information, please read the Castlight privacy policy.

Castlight Health has partnered with your employer to help you get the most out of your health plan and benefits. Everything you see in Castlight—including perks and resources you’re eligible for, prices for doctors and procedures, or recommendations for care—is personalized for you and your plan.

We take your privacy seriously, and we want to protect your Castlight account so only you and family members on your plan can access it. In order to personalize your account, we first need to confirm that your personal information matches the information we’ve received from your medical plan. Therefore, for security reasons, if your information does not "match," you won’t be able to access your account. What information can I see about my family members? And what information can my family members see about me?
