Create Your Google Tag Manager Account Easily Simple-Guide
To begin the process, we recommend creating a Google Tag Manager (GTM) account. Please visit Google Tag Manager's official page. Step 1: If you are presently signed into your Gmail account, you will be automatically authenticated into GTM. If you don't already have a Gmail account, we recommend that you create one and log in to your favorite browser before visiting Google Tag Manager's main page. Step 2: After logging in, create a GTM account. Simply click the "Create Account" button. Step 3: When creating a GTM account, fill out the form fields with the required information. It is worth noting that you can manage many containers under the same GTM account. Source: https://www.enthuons.com/a-simple-guide-to-setting-up-your-gtm-account-and-installing-the-script/
