Kite app code vs external TOTP vs SMS OTP: which second factor to use

Sat, 20 Jun 2026 00:00:00 +0000

Kite offers three ways to satisfy the second factor of a two-factor login: the in-app app code, an external authenticator TOTP, and SMS OTP. An external authenticator TOTP is the most secure and most reliable of the three, because it computes codes offline, removes the SIM and the telecom network from the attack surface, and lets you log in to Kite web without opening the Kite mobile app. The in-app app code is a solid default; SMS OTP is the weakest link and is best treated as a fallback only.
