2727To log out and re-authenticate, type `/logout` at the Claude Code prompt. Logging out also resets your first-launch setup state, so the next time you run `claude` it walks you through login and setup again.

29To stay signed in to multiple accounts at once, such as work and personal accounts, give each account its own configuration directory. When you start `claude`, set the [`CLAUDE_CONFIG_DIR`](/docs/en/env-vars#variables) environment variable to the directory for the account you want to use. Each directory has its own settings, session history, and claude.ai login or API key. For example, in Bash or Zsh, add this alias to `~/.bashrc` or `~/.zshrc` so that `claude-work` uses your work account while `claude` keeps your personal one:
30
31```bash theme={null}
32alias claude-work='CLAUDE_CONFIG_DIR=~/.claude-work claude'
33```
34
35After you open a new terminal and run `claude-work` for the first time, Claude Code walks you through login and setup for the new directory. Separate directories don't keep two Claude Console sign-ins [without an API key](#sign-in-without-an-api-key) apart, because Claude Code stores that kind of sign-in outside the configuration directory.
