Name and password guidelines

When choosing usernames and passwords for users and groups you add to your Google for Work account, consider the following:

  • Usernames can contain letters (a-z), numbers (0-9), dashes (-), underscores (_), apostrophes ('}, and periods (.).
  • Usernames can't contain an equal sign (=), brackets (<,>), plus sign (+), or more than one period (.) in a row.
  • Passwords can contain any combination of ASCII characters and must contain a minimum of 8 characters.
  • First and last names support unicode/UTF-8 characters, with a maximum of 60 characters.
  • Periods (.) are not ignored as they are in a account. If you create a user account called username, this user will not be able to receive messages addressed to, or, or any other combination of periods. To let a user receive mail with these variations, create an email alias for them.
Because abuse and postmaster are reserved aliases, you cannot use them as usernames or aliases. (Learn more)
