Generate the Domain Verification TXT Record.
Sign in to your Google Admin Console at admin.google.com
Navigate to Account > Domains
Click on Manage domains
If your domain is showing as "Verified," you may not see an option to regenerate the record immediately. You would typically need to enter the Domain Setup Wizard again or navigate to the area where the domain was verified. If Google Workspace detects your domain is no longer verified after a transfer, you will see an option like "Start verification" or "Verify ownership". Follow the prompts and choose the TXT record method. The Admin Console will then display a new, unique verification code and the Name usually @ or blank. Once you have this record, you must add it to your DNS host's settings to re-verify the domain.
