# codex logout

> Remove stored authentication credentials

## Syntax

```bash theme={null}
codex logout
```

## Description

The `logout` command removes your stored authentication credentials from Codex. After logging out, you'll need to run `codex login` again to authenticate.

## Usage

```bash theme={null}
codex logout
```

This removes:

* ChatGPT OAuth tokens
* API keys
* Any other stored credentials

## Examples

### Standard Logout

```bash theme={null}
# Remove credentials
codex logout

# Output:
# Logged out successfully
```

### Verify Logout

```bash theme={null}
# Log out
codex logout

# Check status
codex login status

# Output:
# Authenticated: No
```

### Switch Accounts

```bash theme={null}
# Log out of current account
codex logout

# Log in with different account
codex login
```

### CI/CD Cleanup

```yaml theme={null}
# GitHub Actions - cleanup after job
- name: Cleanup Credentials
  if: always()
  run: codex logout
```

## 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:

```bash theme={null}
# 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:
   ```bash theme={null}
   codex login status
   ```

2. Manually remove from keychain (macOS):
   ```bash theme={null}
   security delete-generic-password -s "codex-cli" -a "oauth"
   ```

3. Or remove config file:
   ```bash theme={null}
   rm ~/.codex/auth.json
   ```

### Permission Errors

If you see permission errors:

```bash theme={null}
# macOS - may need to allow terminal access to keychain
# Go to: System Preferences > Privacy & Security > Privacy > Keychain
```
