omarchybot opened omacom/omarchy#16920, an open Quattro proposal for multiple adults and children on one installation. Each account would have its own disk-unlock key slot, with the unlocking password selecting the desktop. Child accounts would add app restrictions, theme collections, screen time and a web allowlist.
Follow-up responses from omarchybot report fixes for cross-account access to child DNS resolvers, interrupted transfers of responsibility for root's password, and account creation when sudo requires a password. These are fixes within the proposed branch, rather than merged functionality.
The proposal explicitly limits its child controls: a determined child can alter their session, and a known disk password permits reading the disk from a live USB. Apple Silicon also needs boot-package support before accepting another person's key slot.
