Kite Connect authentication errors: invalid app code and incorrect api_key or access_token

Sun, 21 Jun 2026 00:00:00 +0000

Kite Connect authentication errors fall into two layers that are often confused: the human Kite login, where “Invalid app code” means the second-factor code failed, and the Kite Connect API , where “Incorrect api_key or access_token” means a programmatic session is invalid or expired. The first is almost always a device-clock problem on the time-based login code; the second is almost always the daily 6 a.m. expiry of a Kite Connect access token, returned to your program as an HTTP 403 with a TokenException. They look similar because both involve a token and both block access, but they sit at different layers and have different fixes.
