macOS 15 - Sequoia

The macOS system must disable unattended or automatic login to the system

STIG ID: APPL-15-002066 | SRG: SRG-OS-000104-GPOS-00051 | Severity: High | CCI: CCI-000764,CCI-000366 | Vulnerability ID: V-268512

Description

Automatic login must be disabled.When automatic logins are enabled, the default user account is automatically logged on at boot time without prompting the user for a password. Even if the screen is later locked, a malicious user would be able to reboot the computer and find it already logged in. Disabling automatic logins mitigates this risk.Satisfies: SRG-OS-000104-GPOS-00051, SRG-OS-000480-GPOS-00229
