Login Command

The login command authenticates you with Codegen’s services, enabling access to AI features and private codemods.

​

Usage

codegen login [--token <token>]

​

Options

• --token <token>: Directly provide an authentication token instead of using browser-based authentication

​

Authentication Flow

1. Browser Authentication (Default):

   codegen login
   

   This will:

   • Open your default browser
   • Direct you to the Codegen authentication page
   • Automatically complete authentication when you log in

2. Token Authentication:

   codegen login --token your-token-here
   

   Useful for:

   • CI/CD environments
   • Machines without browsers
   • Automated scripts

​

Validation

After logging in, Codegen will:

1. Validate your credentials
2. Store the authentication token securely
3. Configure your environment for subsequent commands

​

Environment Variables

• CODEGEN_TOKEN: Alternative way to provide authentication token
• ENV: Set to prod or staging to specify environment

​

Examples

# Standard login with browser
codegen login

# Login with specific token
codegen login --token abc123

# Login to production
ENV=prod codegen login

​

Common Issues

1. Browser doesn’t open:

   • Use the --token option instead
   • Check your default browser settings

2. Token expired:

   • Simply run codegen login again
   • New token will replace the old one

3. Permission issues:

   • Ensure you have the correct permissions
   • Contact support if problems persist
