Guide outlines methods to run multiple separate Claude AI accounts simultaneously

A developer details methods to run multiple Claude accounts on desktop and terminal simultaneously. The core issue is that the official apps store login data in a single directory per system, forcing users to sign out and in to switch accounts.

This can be done manually via shell commands or automated with scripts and aliases for convenience. The article explains why simpler workarounds fail and emphasizes the need for complete application separation.
