How can I add or update TXT Records in my Wix account?
You can add or update your TXT records from the Domains page of your Wix account.
To add or update a TXT record: Sign in to your Wix account > from the top menu, hover over Subscriptions > click Domains > under My Domains, next to the relevant domain, click Manage.
Under Domain Summary, select the Advanced tab > next to DNS Records, click Manage > next to TXT(Text), click Add a new TXT record to add, or click the pencil icon to edit > enter the information in the pop-up window > click Save.
Note: If your domain is connected to your Wix site via Pointing, your domain host is in control of your TXT records.
