Additional info on Google Accounts
A Google Account is made up of an email address and password of your choosing. The Google Account acts as a secure authentication method to keep your online accounts private while also allowing you to access numerous Google services with a single sign-in. If you already have a Gmail account, it comes with built-in Google Apps, such as Google Drive. Google Drive is an online digital file storage. Once you have a Google Account, just go to Google Drive and sign in.
