If you sign in to Google+ for the first time and a basic profile appears with your name and date of birth (your date of birth is only visible to you), the G Suite administrator for your organization might have created it for you. You can include additional information, such as a profile photo, contact information, and posts. Learn more about setting up your profile.
Your name, profile photo, and cover photo are visible to the public. Your administrator can limit the rest of your profile information to your organization. They can also hide your profile in web search results. Your admin can also restrict your posts to people in your organization, but you can choose to override this. Learn about sharing posts outside of your organization.
Your G Suite administrator sets your account's Google+ access setting, which determines what you can see or interact with. To view a list of options your administrator may have chosen, see Manage Google+ content sharing.
