By default, Learning accounts sit on a Learning subdomain:

This subdomain can be customized to something like Read on to learn how.

How to Secure a Custom Domain

To secure a custom domain, contact the Support team at Support will request an AWS certificate on the customer's behalf. The customer then has 72 hours to validate the request.

📝 Important Note: It's vital that customers have a technical specialist who can validate the AWS certificate within the 72-hour timeframe.

After Learning provides the AWS certificate, the customer creates two CNAME DNS records. These records validate the requested AWS certificate.

Securing a CNAME

Point the new subdomain to Learning

Once Learning has started the 72-hour clock, the custom subdomain must be secured.

Follow the steps below to secure a custom domain.

  1. Locate the CNAME records for the custom domain within the domain registrar’s control panel.

  2. A CNAME record, or Canonical Name record, is a type of alias used by the Domain Name System (DNS). Among other things, a CNAME record can be used to make a subdomain an alias of an external website.

  3. If a CNAME record already exists, look for the option to edit this record. If a CNAME record doesn't exist for the subdomain yet, look for an option to add a new record.

  4. Point the CNAME record from the subdomain to the [Learning subdomain] For example, if the subdomain is, then point the CNAME to

Some providers may have slightly different naming conventions for certain items, but the above steps should generally be a similar process to retrieve the needed CNAME.

📝 Note: This change may take up to 48 hours to propagate but it typically happens sooner. Some users may see the update in as few as 4 hours.

Important Considerations

Notify users 48 hours in advance to mitigate questions or concerns. After securing your custom domain, the previous domain will be disabled. While users should be redirected from the previous domain, bookmarks, assignment links, and shared links containing the default subdomain may be corrupted by the change, causing users to encounter an error if they visit the defunct domain.

Update affected integrations. Any software that integrates with Learning via subdomain, such as Zendesk, must be updated with the new custom domain.

💡 Note: the Skills app does support custom domains.
