July 11th, 2025

Set Up Custom Domain and SSL in Power Pages with GoDaddy

Adding a custom domain and SSL certificate to your Microsoft Power Pages site creates a secure, professional, and brand-aligned experience.

In this step-by-step guide, you’ll learn how to:

  • Configure CNAME and TXT records in GoDaddy DNS

  • Add and verify a custom domain in Power Pages

  • Bind an SSL certificate – either auto-generated or manual

Whether you’re an admin or a Power Platform developer, this tutorial helps you ensure your Power Pages portal is live, secure, and ready for public access.

Prerequisites

Before starting, make sure you have the following:

  • GoDaddy account access with DNS management privileges

  • An active and provisioned Microsoft Power Pages portal

  • An SSL certificate (.pfx file) – or plan to use the auto-generated certificate provided by Power Pages

💡 Tip: If your SSL certificate is in a different format, you can convert it using a tool like InterSSL PFX Converter.

Step 1: Add or Verify a CNAME Record in GoDaddy DNS

To map your custom domain to Microsoft Power Pages, begin by adding a CNAME record in your GoDaddy DNS settings.

Follow these steps:

  1. Log in to your GoDaddy account

  2. Navigate to My Products > Domains, then select your domain (e.g., yourdomain.com)

  3. Click Manage DNS

  4. Under Records, click “Add” (or “Edit” if the record already exists)

  5. Fill in the CNAME details:

    • Type: CNAME

    • Host: portal

    • Points to: yourportal.powerappsportals.com

    • TTL: 1 Hour

  6. Click Save

📌 Note: Replace yourportal.powerappsportals.com with the actual URL of your Power Pages portal.

Step 2: Check CNAME Propagation Globally

After setting up the CNAME record in GoDaddy, it’s important to confirm that the change has propagated across DNS servers worldwide.

Here’s how to check:
  1. Visit whatsmydns.net
  2. In the search box, enter your subdomain – for example:
    portal.yourdomain.com
  3. From the dropdown, select CNAME
  4. Click Search
  5. You should see multiple green checks and the value pointing to your Power Pages portal

 ⚠️ Note: If your domain is not resolving correctly, wait 15-30 minutes and check again. DNS propagation can take up to 24 hours.

Why this matters:

Verifying propagation ensures that your domain correctly maps to the Power Pages environment before applying SSL or proceeding with TXT verification.

Step 3: Add Your Custom Domain in Microsoft Power Pages

Once your DNS records are set up and propagating, it’s time to add the domain to your Power Pages site.

Follow these steps:

  1. Go to the Power Platform Admin Center

  2. Navigate to:
    Environments → Select your environment → Power Pages site → Custom Domains

  3. Click + Add Custom Domain

  4. In the domain field, enter your mapped subdomain:
    Example: portal.yourdomain.com

  5. Upload your SSL certificate (.pfx) and provide the associated password

Troubleshooting Tips:

If the custom domain doesn’t register or validate:

  • Refresh the Power Platform Admin Center

  • Clear your browser cache or open in Incognito Mode

  • Try a different browser (Chrome, Edge, Firefox)

Once saved, your domain will appear under the Custom Domains list with a “Pending Validation” status.

Step 4: SSL Binding for Your Custom Domain

Once your domain is successfully added and validated, Power Pages will automatically attempt to bind an SSL certificate to secure your custom domain.

Here’s what to expect:

  • If successful, an SSL certificate will be auto-generated and bound to your domain

  • It may take a few minutes for binding to complete – refresh the page to check status

What if SSL binding fails?

If the SSL certificate doesn’t bind automatically:

  1. Wait a few minutes and refresh your browser

  2. If it still fails, manually upload a .pfx certificate from your SSL provider (e.g., GoDaddy)

  3. Return to the Custom Domains panel and retry the validation

🔐 SSL ensures your Power Pages site is accessed securely via HTTPS – essential for data protection and SEO.

Step 5: Add a TXT Record in GoDaddy for Domain Verification

To verify domain ownership, Microsoft Power Pages requires a TXT record in your GoDaddy DNS settings.

Steps to Add the TXT Record:

  1. Sign in to your GoDaddy account

  2. Go to My Products → Domains → Manage DNS

  3. Click “Add Record”

  4. Select the following details:

    • Type: TXT

    • Host: _dnsauth.portal

      (Use the exact host value provided by Power Pages if different)

    • TXT Value: (Copy this from your Power Pages domain setup page)

    • TTL: 1 Hour

  5. Click Save

This TXT record helps Microsoft validate that you own the domain before enabling secure binding.

Step 6: Verify TXT Record Propagation Globally

Once your TXT record is added in GoDaddy, the next step is to confirm that it has propagated across global DNS servers.

How to check TXT propagation:

  1. Visit whatsmydns.net

  2. In the search field, enter your full TXT record host, like:
    _dnsauth.portal.yourdomain.com

  3. From the dropdown, select TXT

  4. Click Search

  5. Check that the expected TXT value is visible from most (or all) DNS nodes

DNS propagation can take from a few minutes to 24 hours. If you don’t see the value right away, wait and retry later.

Why this matters:

Verifying TXT propagation ensures Microsoft Power Pages can confirm domain ownership – a critical step before final SSL binding and public launch.

Step 7: Final Domain Validation in Power Pages

Once the TXT record has propagated successfully, it’s time to complete the process by validating your domain in Microsoft Power Pages.

Final Validation Steps:

  1. Go back to the Power Platform Admin Center

  2. Navigate to:
    Your environment → Power Pages site → Custom Domains

  3. Find your domain in the list (e.g., portal.yourdomain.com)

  4. Click the “Validate” button next to it

What happens next?

  • If the TXT record is found and correct, Power Pages will confirm ownership

  • SSL will be automatically applied to your custom domain

  • Your site will now be live at https://portal.yourdomain.com – secured and ready to go!

🔐 Note: You can re-check the SSL certificate status by revisiting the Custom Domains panel or viewing your site in a browser with HTTPS.

FAQs

How can I connect a custom domain to Microsoft Power Pages using GoDaddy DNS?

You can connect a custom domain to Microsoft Power Pages by configuring a CNAME record in your GoDaddy DNS settings and validating it through the Power Platform admin center. Once validated, upload an SSL certificate and complete the domain binding steps - no code required. This blog provides a step-by-step guide using a real GoDaddy DNS example.

Do I need to write code to enable SSL for a custom domain in Power Pages?

No, you don't need to write any code. Microsoft Power Pages offers a no-code interface to upload your SSL certificate (in PFX format), choose a hostname, and complete domain validation. The SSL binding process is handled entirely through the Power Platform admin portal.

What type of SSL certificate is required for Microsoft Power Pages?

Power Pages requires a PFX (Personal Information Exchange) SSL certificate file with a private key. This certificate must be password protected and match the custom domain you're binding. You can generate a PFX file using tools like OpenSSL or export it from a certificate authority.

Can I use Power Pages without buying a custom domain?

Yes, Power Pages provides a default Microsoft subdomain (e.g., yourorg.powerappsportals.com). However, for branding and trust, using your own domain with SSL is recommended. This guide walks you through securing a custom domain via GoDaddy DNS.

How does this differ from adding a file upload to Power Apps Portals?

Custom domain + SSL setup focuses on domain branding and security, whereas file uploads relate to form submissions. If you want to securely upload documents via a Power Apps portal, refer to our step-by-step guide:
