When you have domain aliasing enabled, you have the option of setting up a custom domain n your platform. This means you can set up a domain that affiliates can log in through. Instead of the standard 'https://yourdomain.tapfiliate.com', you can set up 'https://affiliates.yourdomain.com' or change the top-level domain (TLD) to one of your choice.
We arrange a dedicated SSL certificate to secure this domain for you.
To set up a custom domain, please follow our guide: How to use a CNAME to setup domain aliasing.
