Hi I'd like to ensure that no individual in a group email could see other individual's contact information for privacy purposes. What is the correct method to do this? Much appreciated!
Then you need to on the 2fa then google authenticator so that your gmail will not easily open to those strangers or let say hacker on your account. Creating second password also makes it advantage of yours so that you will recover your account in case of emergency.
That's not an answer to the question he was asking.
The correct answer is to use
BCC - which is a general email feature not specific to Gmail.
