Syntax

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

codex logout
This removes:
  • ChatGPT OAuth tokens
  • API keys
  • Any other stored credentials

​
Examples

​

# Remove credentials

# Output:
# Logged out successfully

​

# Log out
codex logout

# Check status
codex login status

# Output:
# Authenticated: No

​
CI/CD Cleanup

# GitHub Actions - cleanup after job

  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: 
# 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
