You can embed public forms on your website, but the guest login page is not embeddable.
If you’d like guests to access secure forms or tasks, you can either embed individual public forms that require guest login or share a direct link to your organization at https://www.cognitoforms.com/yourorganizationname. Make sure to replace ‘yourorganizationname’ with your organization’s Cognito Forms URL – you can find this in your browser’s address bar when logged in to your organization.
