Authentication Flow Details

  1. Local server: Sher starts a temporary HTTP server on localhost to receive the OAuth callback
  2. GitHub OAuth: You’re redirected to GitHub to authorize Sher
  3. Token exchange: GitHub sends an auth token to the local server
  4. Token verification: Sher verifies the token with the API server
  5. Storage: The token and username are saved locally
Your authentication token is stored in ~/.sher/auth.json. Keep this file secure.

​
Timeout

The login flow times out after 2 minutes. If you don’t complete authentication within that window: 
  Login timed out — no response within 2 minutes.
Simply run sher login again.

​
Security

  • Authentication uses GitHub OAuth
  • No passwords are stored
  • The token is used for API requests
  • Token is stored locally in ~/.sher/auth.json
  • You can revoke access anytime via GitHub settings
