Run two Claude Code accounts simultaneously on your computer without re-authenticating by using separate configuration directories.

Notes

Requires separate Anthropic accounts (different emails).
Update Claude Code: npm install -g @anthropic-ai/claude-code.
If re-authentication occurs, verify CLAUDE_CONFIG_DIR with echo $CLAUDE_CONFIG_DIR.

mkdir ~/.claude-personal
mkdir ~/.claude-work

Add Aliases to Shell Config

Open ~/.zshrc (or ~/.bashrc for Bash) in an editor:
```
nano ~/.zshrc
```

Add:

alias claude-personal="CLAUDE_CONFIG_DIR=~/.claude-personal claude"
alias claude-work="CLAUDE_CONFIG_DIR=~/.claude-work claude"

Save and reload:
```
source ~/.zshrc
```

Authenticate Each Account
- For account 1:
```
claude-personal
```
  After authentication, the credentials are saves to ~/.claude-personal.
- For account 2:
```
claude-work
```
  After authentication, the credentials are saves to ~/.claude-work.
