Advanced: Custom Domain mapping

With OptiSigns Pro and Enterprise plans, elevate your branding by mapping your custom domain for the OptiSigns Management Portal.

For example: you can map your sub-domain: so that your users can log in and use the portal from and use the app like the screenshot below


Let's jump in and get started!

1) Activate your OptiSigns sub-domain (in this example:

Go to the Branding page of your Account Management Settings:

Type in your desired sub-domain for In this case, we type in "abcmedia".
Don't worry about, you will map your own domain in the next step.

2) Map CNAME alias for your domain/sub-domain:

Refer to your domain host documentation for more specific details.

Here are the generic steps:

  1. Go to your domain’s DNS records.
  2. Add a record to your DNS settings, selecting CNAME as the record type.
  3. Return to the first window or tab and copy the contents of the Label/Host field.
  4. Paste the copied contents into the Label or Host field with your DNS records.
  5. Return to the first window or tab and copy the contents of the Destination/Target field.
  6. Paste the copied contents into the Destination or Target field with your DNS records.

    Your record should look similar to one of the tables below:

    CNAME Record

    Record type Label/Host field Time To Live (TTL) Destination/Target field
    CNAME login 3600 or leave the default
  7. Save your record.
    CNAME record changes can take up to 72 hours to go into effect, but typically they happen much sooner.
