Show HN: Run multiple instances of Codex(GUI) each with their own auth (github.com)

A new local workaround has been announced for macOS users that allows running multiple instances of the Codex application, enabling separate OAuth accounts for each instance. This solution, while unsupported, creates isolated environments for each account, including separate directories for profiles and project data. Users can execute a simple script—`codex-multi-account.sh`—to launch additional Codex windows with unique settings, facilitating the management of different accounts without cross-contamination of data. This development is significant for the AI/ML community as it enhances workflow flexibility for individuals and teams using Codex for various projects or clients. By allowing multiple authenticated sessions simultaneously, users can better compartmentalize their work. The script provides options to share specific project histories selectively while maintaining distinct authentication credentials. This capability not only streamlines productivity but also enhances user control over personal and professional data, reflecting an increasing need for adaptability in the growing landscape of AI tools.
