I received this email from a coworker just a bit ago.

How goes life in your area?

Would you have any idea whether we can assign users to the ‘guest’ security group for SQL Server databases? When to go to Security…Users in SSMS I see a guest account. I’d like to use the account whereby I assign read-only privileges and when someone from outside our department needs some kind of read-only access, I could have Security Services assign them to this group. I realize I could create a new security group as well, but thought using an established group might save some time (and this group’s name aptly describes the role!).

Thanks, and hope you’re well!
