1. Login to Admin Console.
  2. From the Admin console dashboard, go to Users.
  3. Select the organizational unit to which you want to add the user. (You might need to click filter to see organizational units.)
  4. Click Add and select Add user.
  5. Enter the new user's First Name, Last Name, and Primary email address.
  6. Tip: Before assigning an email address, check if a user has an existing account with a Google service such as Gmail or Google Hangouts.
  7. If your account has multiple domains associated with it, select the domain you want to add the user to.
  8. The field to the right of the @ sign is a drop-down list with available domains. The domain you select will be the portion of the user's email address that appears after the @ sign.
  9. Create a new user
  10. (Optional) Set the user's initial password.
  11. The Admin console generates a temporary password for the new user, using a mixed pattern of symbols, upper and lower case letters, and numbers. The length of the password will be the greater of the required minimum (eight), or the minimum password length you've set for your domain.
  12. To set a different initial password, click Set password and enter the password twice. Google requires the password to be at least eight characters. See Password help for tips on creating a strong password.
  13. Set user password
  14. (Optional) Click Additional info to add contact information (like the user's mobile phone number or work address) and employee details (like the user's employee ID or cost center) to the user's profile. If you want to add even more information to a user's profile, you can create custom attributes. User profile information is visible in the Admin console and Gmail contacts.
  15. Click Create.
  16. Click Email instructions or Print instructions to deliver the account information to the new user.
  17. If you email the instructions, be sure to send the message to an email address that is currently accessible to the user, not to the new email address.
  18. Click Done.
  19. (Optional) Edit additional user settings.
  20. To set other user settings, such as adding the new user to groups or omitting the user's information from your G Suite Directory, click the user's name in the list. See Manage user accounts for instructions.
