What Gets Removed

The logout command removes:

1. OAuth Tokens: ChatGPT authentication tokens
2. API Keys: Stored OpenAI API keys
3. Session Data: Any active session information

Credential Storage

Credentials are stored in your system’s secure storage:

• macOS: Keychain Access
• Linux: Secret Service API (gnome-keyring, KWallet)
• Windows: Windows Credential Manager

The logout command removes entries from these secure stores.

After Logout

To use Codex again, you must re-authenticate:

# Log out
codex logout

# Log back in
codex login

# Or use API key
echo "$OPENAI_API_KEY" | codex login --with-api-key

Troubleshooting

Credentials Still Present

If credentials persist after logout:

1. Check login status:

   codex login status
   

2. Manually remove from keychain (macOS):

   security delete-generic-password -s "codex-cli" -a "oauth"
   

3. Or remove config file:

   rm ~/.codex/auth.json
   

Permission Errors

If you see permission errors:

# macOS - may need to allow terminal access to keychain
# Go to: System Preferences > Privacy & Security > Privacy > Keychain
