Sign in with your Choice account

Your Choice credentials are the login — there is no separate password for this app to store. They are used once to open a broker session and are never written to disk.

Declare this IP against your API key
202.179.94.58
This is the engine's outbound address — the one Choice sees. Your own browser IP is irrelevant, and a VPN on this machine will break it.

Sent once over HTTPS to your engine, exchanged for a broker session, and held in memory only. Never stored in this app, never placed in browser storage, and never returned to the page.

How this works
  1. Generate an API key at finx.choiceindia.com → Profile → Settings → Generate API Key.
  2. Declare the engine server's static IP against that key — not your laptop's. Choice rejects requests from any other address, and VPNs always fail.
  3. Sign in here. We call LoginTOTP → GetClientLoginTOTP → ValidateTOTP; Choice returns the OTP itself, so there is no authenticator app.

Sessions are day-scoped, matching Choice's own — you will be signed out at end of day. Each user gets an isolated broker session; nobody sees anyone else's positions.
