How ChatGPT Authentication Works

Unlike Claude Desktop and Claude Code which use JWT tokens, ChatGPT connects via OAuth authentication. This means you authenticate directly with your Wallet email and a verification code — no need to manually copy API tokens.

ChatGPT (OAuth)

  • Login with Wallet email
  • Verify with email code
  • Automatic token management

Claude (JWT Token)

  • Generate token in Wallet settings
  • Paste into config file
  • Manual token rotation
