The phone user will not be able to use Google services that require an account (such as Gmail, Drive, Calendar, or Google Play).
You will lose access to subscriptions and content purchased through this account on Google Play and YouTube (for example, applications, games, music, TV series).

After that, select the menu item Accounts and backup.
