Here's the definitive 2025 guide—"Master Your Domains on Squarespace: Google Domains Edition"—detailing everything you need to know about managing your domain now that Google Domains has evolved into Squarespace Domains.

1. The Migration Is Complete — What This Means for You

On September 7, 2023, Squarespace acquired Google Domains—along with all customer accounts and registered domains.

By July 10, 2024, every domain had been fully migrated to Squarespace Domains.

3. How to Access and Manage Your Migrated Domain
1. Logging Into Your Squarespace Account

If you already had a Squarespace account linked to the email used for Google Domains, just log in. Your domains will appear in the Domains Dashboard.

If you did not have a Squarespace account, one was automatically created using your Google Domains email. Log in at squarespace.com/login → Continue with Google, then verify your email and set a password.

2. Manage Your Domain Settings

From your Squarespace Domains Dashboard, you now have control over:

Billing and auto-renew settings

Contact information (Registrant, Admin, Tech, Billing)

DNS Records, Nameservers, DNSSEC, WHOIS privacy, etc.
Squarespace Help

3. Billing and Renewal Notes

Domains keep any remaining prepaid term from Google. Renewal happens according to Squarespace's pricing.

You'll receive renewal reminders 15 days prior to billing. Auto-renewal can be disabled in settings.

4. Forwarding Rules Copied Over—But Sometimes Needs Reconfiguration

Your original domain and email forwarding rules should work, provided you're using Google's default nameservers.

If you used custom nameservers or third-party services, you may need to manually re-add DNS and forwarding rules via the dashboard.

4. Domains Registered via Google Workspace (Resold Domains)

If you purchased the domain at the same time as setting up Google Workspace:

These are considered resold domains, where billing is managed via Google Workspace, while DNS and most settings are controlled through Squarespace.

To fully consolidate billing and management under Squarespace, you can cancel via Google Workspace and claim the domain entirely through Squarespace.
